2. Why is open pit mining so devastating to the environment?
A. It exposes dangerous chemicals buried in the earth's crust.
B. It releases a lot of carbon dioxide into the air.
C. It causes massive erosion of sand.
D. It completely removes any available topsoil.​

Answers

Answer 1

Answer:

D. It completely removes any available topsoil.​

Explanation:

Open pit mining strips off the top layer of the soil in order to access near surface mineral deposits. Most near surface deposits are usually rock aggregates, coal, copper etc.

In order, to access these minerals, large amount of earth must be removed by earth moving machines.

Open pit mining greatly unsettles the ecosystem in mining regions and it leaves the surface bare and not suitable for agricultural activities.

Answer 2

Open pit mining so devastating to the environment completely removes any available topsoil.​ Thus, option D is correct.

Large volumes of heavy metal-containing dust will be produced by an open pit mine, and the disposal of toxic waste in pursuing ponds will have an effect on the ecosystem and drinking water supplies when they appear on the topsoil.

Forest loss, sedimentation, contamination of adjacent wetlands and stream systems, alteration of soil profiles, and a boost in noise level are just a few of the environmental effects that may result from the exploration, building, operation, and cost of living. Therefore, option D is correct.

What are the disadvantages of wind power

Answers

Answer:

The two major disadvantages of wind power include initial cost and technology immaturity. Firstly, constructing turbines and wind facilities is extremely expensive. The second disadvantage is technology immaturity. [1] High cost of energy can, in part, be addressed directly with technology innovations that increase reliability and energy output and lower system capital expenses. Offshore wind energy produces more energy than onshore wind energy, but costs much more to establish. The primary costs of wind turbines include construction and maintenance. [1] New technology is needed to lower costs, increase reliability and energy production, solve regional deployment issues, expand the resource area, develop infrastructure and manufacturing facilities, and mitigate known environmental impacts.

Hope This Helps!  Have A Nice Day!!

Answer:

The advantages of wind energy are more apparent than the disadvantages. The main advantages include an unlimited, free, renewable resource (the wind itself), economic value, maintenance cost, and placement of wind harvesting facilities. First and foremost, wind is an unlimited, free, renewable resource.

Which statement describes a wave's wavelength?

Answers

Answer:  The distance between two crests

Explanation:

The wavelength [tex]\lambda[/tex] is equivalent to the actual distance that the disturbance (wave) travels over a certain time. It is also defined as the distance traveled by a periodic disturbance that propagates through a medium in a given time interval, for example the distance beteween two crests of the wave.

It should be noted that the wavelength, also known as the spatial period is the inverse of the frequency [tex]f[/tex]:

The number of women in high-tech professions continues to lag. C. The pay gap is closing in the developed world. D. Women are as likely as men to hold senior management positions. Please select the best answer from the choices provided. A B C D

Answers

Answer:

D. Women are as likely as men to hold senior management positions

Explanation:

There has been a lot of talk and improvements when it comes to the equality between the men and women, be it in the rights they have, or with the wages they earn. The developed countries have sorted those problems out, as all men and women are equal in front of the law, they have the same rights, the discrimination is punishable and forbidden, and the wages have equalized when it comes to the same amount of working hours for the same job. The women though are still not as likely to hold senior managerial positions despite of this. The main reasons behind this is that the women tend to prefer the family, especially when it comes to having and raising children, which of course is a big obstacle for the career, and the other reason is that the women tend to be less ambitions on average than the men, thus they are more often satisfied with what they got, and do not want to put additional pressure in their lives.

Answer:

The answer is D (Women are as likely as men to hold senior management positions.)

how does carbon tax encourage less use of fossil fuels?

Answers

Answer:

Explanation:

The carbon tax is a tax, which is to say it is an expense. It takes about 50 liters to fill our car. Before the Carbon tax was passed, a liter fuel cost between 0.90 and 1.10. Now with the carbon tax firmly in place, a liter costs between 1.15 and a 1.24. That may not sound like much of an increase, but on 50 liters it increases by 12.50 cents. We fill our car once a week. So that means we are spending 50 dollars a month on a tax which is 600 dollars a year.

We are on a fixed income. (Retired). Don't think we don't give that some thought. It certainly does encourage us to cut back on our fuel costs.

Taxation is the kind of expense we all have that we try and avoid if we can. The way to avoid it is to use less of the commodity being taxed.

Specifically, how were the scablands of eastern Washington created?

Answers

Massive erosion was caused due to the Age floods acceleration across the tilted surface of the Palouse slope that resulted in the creation of channelled scablands.

Explanation:

Massive erosion was caused because of the Age floods acceleration that occurs across the Palouse slope’s surface that resulted in the creation of channelled scablands. The eroded sediments were carried to the Pacific Ocean.  

A huge lake known as Lake Missoula was formed during the Pleistocene Ice Ages and the lobes of ice that melt water from the glacier. Mostly the water over flowed the ice dam, forcing it to rise and break thereby creating a huge flood, that carved out both the channelled scablands as well as the Columbia River Gorge.

The Mid-Atlantic Ridge is an example of ______.

a) a convergent boundary.
b) a divergent boundary.
c) a collision boundary.
d) a subduction boundary.

Answers

ANSWER:

The "Mid-Atlantic Ridge" is an example of divergent boundary.

EXPLANATION:

Divergent boundary can be understood as the tectonic plates, the "divergent boundary" or "divergent plate boundary" is known as a linear feature and are moving apart from one another. If you were to look around and search for the "most active divergent plate", then the occurrence can be witnessed between oceanic plates and exists as mid-oceanic ridges.
Final answer:

The Mid-Atlantic Ridge illustrates a divergent boundary, where two tectonic plates move apart, forming new crust from the mantle's upwelling and cooling.

Explanation:

The Mid-Atlantic Ridge is an example of option b) a divergent boundary. In plate tectonics, a divergent boundary is a linear feature where two tectonic plates move apart from each other, resulting in the formation of new oceanic crust from the mantle's upwelling and subsequent cooling. The Mid-Atlantic Ridge, which runs down the center of the Atlantic Ocean, is a prime example of this. As the tectonic plates on either side diverge or move away from the ridge, magma rises from the mantle, hardens, and forms new seafloor and the distinctive rift valley associated with this type of boundary.

What are the following best describes the republic?
-every citizen has a direct flight or say in the government
-citizens elect representatives to be there voice in the government
-The idea of republic originated in Ancient Greece
-republicans are a type of totalitarian Government

Answers

Answer:

-citizens elect representatives to be there voice in the government

Explanation:

Final answer:

A republic is best described as a form of government where citizens elect representatives to govern on their behalf, as opposed to a direct democracy where citizens vote on all issues. The correct answer is b.

Explanation:

The term that best describes a republic is that citizens elect representatives to be their voice in the government. In a republic, individuals do not directly participate in the passing of laws or the day-to-day running of the government but instead choose officials to represent their interests.

This system contrasts with a direct democracy, in which citizens vote directly on legislative issues. The United States is a prime example of a representative democracy or federal republic, where the power rests with the people who participate in the governmental process through elected representatives who serve fixed terms in office.

In the historical context, although the idea of democratic practices can be traced back to Ancient Greece, the modern concept of a republic as experienced in the United States and other democratic countries was developed with the aim of protecting both the voice of the masses and the rights of the minority. Elections, an elected legislature, and mechanisms for the protection of minority rights are all essential features of a republican government.

Explanation:

Answer:

The statement that shows the correct definition of a type of tectonic plate boundary is included in two answers : letter "B" and "C", taking into account that in the two response options the same statement is repeated.

"At a divergent boundary, plates separate".

Explanation:

Divergent boundaries

It occurs when two tectonic plates move away from each other. When these types of boundaries occur, earthquakes are likely to occur and magma (molten rock) leaves the Earth's mantle to the surface. Then it hardens or solidifies and thus a new oceanic crust is created.

Convergent boundaries:

When two plates meet or collide, the impact of collision can cause different reactions: a) cause the edges of one or both plates to buckle into the mountain ranges; or that b) one of the plates bends towards the bottom of the ocean. This type of limits generates chains of volcanoes and earthquakes.

Transformation boundaries:

When two plates that slide together form a limit. The two plates that are found are compensated, divided and transported in opposite directions. The rocks that are in the limit are pulverized. Also, this type of boundary between plates generates earthquakes.

A scientist observes that over several decades, fence posts placed in soil on a slope became tilted. Have erosion, deposition or both occurred in this area? Use evidence to explain gow you know.​

Answers

Answer:

Erosion

Explanation:

At first the fence posts were straight up, but over time that became tilted. The reason fro this is erosion. The erosion managed to remove part of the ground in whist he fence posts have been placed, thus their basis has been weakened, and they have tilted. If the process continues they will soon fall on the ground. Deposition has occurred for sure somewhere, but from this information it is not clear where. There has not been deposition on one side and erosion on other as the fence posts would have been standing straight if that happened. The deposition always occurs as a result of the erosion, but the material can be deposited anywhere from few cm away to several thousands of km away., depending on the transferring medium.

" Both erosion and deposition have occurred in this area. The tilting of fence posts over time in soil on a slope suggests that both erosion and deposition have taken place. Here's the evidence and reasoning:

1. Erosion: If the fence posts are tilting downslope, it indicates that the soil beneath and around the posts has been removed. This process of soil removal is known as erosion. Erosion can be caused by various agents such as water, wind, or gravity. As the soil is eroded from the upslope side of the posts, the posts would begin to lean downhill because the support on the upslope side is gradually lost.

2. Deposition: The presence of tilted fence posts also suggests that deposition has occurred. As erosion takes place on the upslope side, the eroded soil must be transported and deposited elsewhere. The downslope side of the fence posts could be a site of deposition where the transported soil accumulates. This accumulation of soil around the lower part of the posts would cause them to tilt upslope, as the base of the posts becomes buried or embedded in the newly deposited soil.

3. Evidence: The physical evidence of the fence posts' tilt provides a record of the changes in the landscape over time. The angle of tilt can give clues about the direction and possibly the magnitude of the erosional forces at work. If the posts are tilted such that they are leaning downslope, this indicates that erosion has outpaced deposition on the upslope side. Conversely, if the posts are leaning slightly upslope, it suggests that deposition has been significant enough to bury the base of the posts, counteracting the effect of downslope erosion.

In conclusion, the tilting of fence posts on a slope is evidence of both erosion, which removes soil from one area, and deposition, which involves the accumulation of soil in another area. The interplay between these two processes shapes the landscape and can lead to the observed changes in the alignment of the fence posts over time."

Final answer:

Population growth is determined by the birth rate and death rate, as well as migration patterns. While some countries have a negative growth rate, the world population is approximately 7 billion. Population change is also influenced by migration alongside natural changes in the birth and death rates.

Explanation:

The factors typically most responsible for determining population growth are the birth rate and the death rate. While new births certainly contribute to population increases, they are not solely responsible for it. Other factors, such as migration patterns, also play a crucial role in understanding population dynamics.

True or False: Some countries do have a negative growth rate, indicating that their populations are shrinking due to factors such as low birth rates, high death rates, or net emigration. As of the latest data, the current population of the Earth is around 7 billion, marking a significant increase over the past few decades, largely attributed to high fertility rates in developing countries despite a global trend of declining fertility rates.

Population demographics is a complex field that considers the natural population change rate, which is determined by subtracting the death rate from the birth rate. Additionally, immigration and emigration can significantly affect the annual rate of population change for a given area.

an ingenious rock like granite can change into a very different sedimentary rock like sandstone. What processes must have acted on the granite over the years to change this igneous material into sedimentary rock?

Answers

Answer:

very very high heat and pressure

Explanation:

Answer:

Granite is an igneous rock that is composed of four minerals. These minerals include quartz, feldspar, mica, and hornblende. Granite is formed from the solidified silicic magma. This happens within the Earth’s crust. It can be exhumed, i.e. it is brought closer to the surface. This is done via extensive erosion of the rock layers that are present above the granite through the process of faulting. Once the granite is exposed, it is subjected to the usual weathering and erosion, and this links it to the sedimentary part of the rock cycle.
