What are convection currents and how do they promote cycling of matter?

Answers

Answer 1
Convection currents is the movement of a fluid or a gas from one particular location to another location. This motion is created by the difference in the density or the temperature of the fluid or gas in the two locations. It could also be used in the movement of energy from one location to another due to the temperature gradient. For convection current in the atmosphere, it could be describe in the rising of warm air towards the upper portion of the atmosphere while the colder air goes under it. This happens because warmer air would have less density as compared to the colder air.

Which of the following physical characteristics can be found in the southern grassland countries? a. large rivers c. tropical lowlands b. mountains d. all of the above

Answers

I believe its, D. All of the above.

Answer:

d. all of the above

Explanation:

    The countries that have this bioma are Paraguay, Uruguay, Brazil, and Argentina.

    The main feature of the southern grassland is its vegetation, which has a herbaceous composition, that is, basically formed by grasses and small plant species, not exceeding 50 cm in height. This landscape type has two well-defined types: so-called clean fields and dirty fields.

    The clear fields occur when the vegetation has no shrubs, gaining a more homogeneous, that is, more regular landscape, without very large differences between one part and the other. Dirty fields, on the other hand, occur when there is a greater presence of these shrubs, which “blend” with the landscape.

A point charge Q is located a short distance from a point charge 3Q, and no other charges are present, then...? A point charge Q is located a short distance from a point charge 3Q, and no other charges are present. If the electrical force on Q is F, the electrical force on 3Q is? b.) F/3 d.)sqrt of 3F

Answers

The relationship between two charges and the electrical force they are experiencing is described using the Coulomb’s law. The Coulomb's law states that: “The degree of the electrostatic force of attraction between 2 point charges is directly proportional to the product of the magnitudes of the 2 charges and inversely proportional to the square of the distance between them.” Where the force is along the straight line joining them. Therefore this is expressed mathematically as:

F = k q1 q2 / d^2

This also means that the electrical force experienced by 2 charges is equal. Therefore if charge Q experiences an electrical force of F, therefore the electrical force on 3Q is also F.


Answer:

F

A piston above a liquid in a closed container had a area of 1m 2squared. The piston carried a load of 350 kg. What will be the external pressure on the upper surface of the liquid?

Answers

In physical science, pressure quantifies the amount of force that is applied at a certain area. Mathematically, this can be transformed as,
                    Pressure = Force / Area

It is also to be noted that force is the product of mass and acceleration due to gravity. 
                 Force = mass x acceleration due to gravity
Substituting,
                Force = (350 kg) x (9.8 m/s²)
                Force = 3430 N

Then, substitute this to the first equation,
                 Pressure = 3430 N / 1m²

ANSWER: Pressure = 3430 N/m² = 3430 Pa

What is the climate of the selva in south america?

Answers

The selva, or the Amazon Basin, has a Tropical Wet climate with year-round warmth and heavy rainfall supporting a rich, biodiverse tropical rainforest.

The climate of the selva, commonly referred to as the Amazon Basin, is classified as a type A climate, also known as Tropical Wet climate. This biome experiences warm temperatures year-round and a high level of rainfall, typically between 175 and 250 cm (65 and 100 inches) annually. Such climatic conditions support a tropical rainforest biome, which is known for its dense, broadleaf evergreen forests with a high degree of biodiversity. The high levels of precipitation and warmth contribute to the lush and diverse ecosystems found within the selva, making it one of the richest habitats on Earth in terms of flora and fauna.

Although development through deforestation, mining, and cattle ranching has posed significant threats to the selva, these regions still house isolated Amerindian groups and a vast array of plant and animal species, some of which are endemic to this specific climate. The selva's future is threatened by these destructive development patterns, and ongoing conflicts may arise over land claims and the autonomy of indigenous peoples.

The Selva in South America, particularly the Amazon Basin, has a tropical wet climate with high rainfall and constant temperatures, creating conditions for dense rainforests and high biodiversity, but is also under threat from deforestation and development.

The climate of the selva, specifically the Amazon Basin in South America, is characterized by a tropical wet climate or type A climate.

This region experiences minimal annual temperature variation and high levels of rainfall, ranging between 175 and 250 cm (65 and 100 inches) annually.

Such conditions are ideal for sustaining the tropical rainforest biome, which is known for its dense canopies of broadleaf evergreen trees and unparalleled biodiversity.

However, the development activities such as deforestation, mining, and cattle ranching have led to ecological pressures in the Amazon Basin. This has also given rise to conflicts over land claims and the livelihood of isolated Amerindian groups who inhabit the region.

Which of the following boundaries is not one of the three types of plate boundaries?
A. divergent
B. transform
C. convergent
D. tectonic

Final answer:

The type of plate boundary not listed among the three types is 'tectonic'. The primary types of plate boundaries are divergent, convergent, and transform.

Explanation:

The correct answer to which type of boundary is not one of the three types of plate boundaries is D. tectonic. The three main types of plate boundaries are:

Divergent boundaries: These are areas where plates are moving apart from each other. An example of a divergent boundary is the mid-ocean ridge system like the one in the Atlantic Ocean.Convergent boundaries: These occur where plates are moving towards each other, which can result in one plate sliding beneath the other in a process called subduction, or by uplifting to form mountain ranges if the plates have similar densities.Transform boundaries: At these boundaries, plates slide past each other horizontally. The San Andreas Fault is a well-known example of a transform boundary.

Rank the gases in the atmosphere in order from most abundant to least abundant

Answers

Final answer:

The atmospheric gases can be ranked from most to least abundant as Nitrogen, Oxygen, Argon, Carbon Dioxide, Neon, Helium, with Ozone and Carbon Monoxide having variable concentrations. Nitrogen is essential for life, while Oxygen is crucial for combustion and respiration. Minor gases like Carbon Dioxide play significant roles in regulating Earth's climate.

Explanation:

The gases in Earth's atmosphere are comprised of a mix of elements and compounds, each varying in abundance. When ranking these gases from most abundant to least abundant, ignoring the variable component of water vapor, we focus on the major gases that make up the vast majority of the atmosphere. The order of abundance is as follows:

Nitrogen (N₂) - Makes up about 78% of the atmosphere. Its presence is essential for life, dilutes oxygen, and is used by living things to make proteins.Oxygen (O₂) - The second most abundant gas, essential for combustion, aerobic respiration, and life processes.Argon (Ar) - A noble gas making up about 0.93% of the atmosphere.Carbon Dioxide (CO₂) - Though it ranks as a minor component, it is the most abundant of minor gases and plays a critical role in regulating Earth's temperature.Neon (Ne) and Helium (He) - Following carbon dioxide in abundance, these noble gases have been present since Earth's formation.Ozone (O₃) and Carbon Monoxide (CO) - These gases have variable abundances due to their active cycles in the atmosphere.

The gases above represent a basic overview, understanding that the concentration of some of these gases can vary based on geographic location, human activity, and environmental factors.

Answers

I'm sure it c....hopefully this helps

Answer:

C. transportation routes

Explanation:

Hoyt’s model was proposed in 1939 and it states that cities grow in sectors and they radiate along travel routes. Also, it considerates that a sector will remain the same because of the function it has and land will be used for the same.

This model gives a big importance to transportation routes which affect the arrengement of the city. Because of this, the answer is that factories and upper-class residential areas radiate from the center of the city along transportation routes.

Which of these materials will decay the fastest to one-fourth of its original amount?

Bismuth-212 half-lives 60.5 seconds

Sodium-24 half-lives 15 hours

Iodine-131 half-lives 8.07 days

Radium-226 half-lives 1600 years

Answers

The elements listed in the choices are radioactive materials. These materials are very unstable because of the high neutron-to-proton ratio in the nucleus. Because of this, they spontaneously undergo nuclear reactions by giving off sub-particles in order to lower the ratio. They emit radiation in the form of alpha, beta or gamma. 

Half-life is the length of time it needs to completely react half of the original amount. For example, it would take Bismuth 60.5 seconds to use up half of its amount. Therefore, the lower the half-life the faster the reaction is and the lesser the residual amount will be. With that being said, the answer would be Bismuth because it only takes seconds.
Final answer:

Bismuth-212 will decay the fastest to one-fourth of its original amount because it has the shortest half-life of 60.5 seconds, requiring only 121 seconds to reach that point.

Explanation:

To determine which material will decay the fastest to one-fourth of its original amount, we need to consider the half-live of each isotope mentioned. The half-life is the time required for half of the isotope to decay. To reach one-fourth (or 25%) of its original amount, an isotope needs to go through two half-lives. Here's a comparison of how quickly each provided material reaches one-fourth of its original amount:

Bismuth-212: Half-life of 60.5 seconds. Two half-lives will take 121 seconds.Sodium-24: Half-life of 15 hours. Two half-lives will take 30 hours.Iodine-131: Half-life of 8.07 days. Two half-lives will take 16.14 days.Radium-226: Half-life is 1600 years. Two half-lives will take 3200 years.

As seen from the comparison, Bismuth-212 will decay the fastest to one-fourth of its original amount as it has the shortest half-life.
