Which of these are the two major sources of nitrate pollution in rivers? the burning of fossil fuels by factories and cars animal wastes and the burning of fossil fuels by cars animal wastes and fertilizers fertilizer runoff and the burning of fossil fuels by cars animal wastes and the burning of fossil fuels by factories

Answers

Answer 1

Answer:

animal wastes and fertilizers

Explanation:

The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.

Compare and contrast the earth and sun centered theories of the universe

Answers

The Earth centered theory about the universe (geocentric theory) is the oldest one recorded. This theory suggested that the Earth is the largest object in the universe. It is the center of the universe, and all of the other objects, like the Sun, Moon, planets, stars, are orbiting around it.

The Sun centered theory about the universe (heliocentric theory) has been developed in the late Middle Ages. This theory suggested that the Sun is actually the center of the universe, not the Earth. That the Sun is the largest object in the universe, and the Earth, Moon, planets, stars, were all orbiting around the Sun.

In reality both of these theories are wrong, with the heliocentric theory being closer to the reality, or rather to how our solar system works, not the universe. Neither the Earth nor the Sun are centers of the universe. They are both just small parts of a much larger picture, where the Sun is the center of the solar system, with the objects in the solar system orbiting around it, while the moons orbit both around the Sun and around their planets. The Sun though is part of a galaxy that has its own center, so the Sun together with all the other objects that orbit around it, orbit around the center of the galaxy.

What are three examples of destructive forces?

Answers

Answer:

- weathering

- earthquakes

- volcanoes

Explanation:

The destructive forces are the natural forces that manage to cause destruction of the preexisting landscape. Some of these forces are the weathering, earthquakes, and volcanoes. The weathering is the process that manages to break apart the rocks, be it in a chemical, mechanical, or biological manner. This process has the tendency to destroy the rocks and level up the landscape. The earthquakes are sudden occurrences that are a result of the adjustments in the crust. Through their strong vibrations, the earthquakes can cause enormous damage to pretty much everything in just seconds and leave ruins behind them. The volcanoes are a destructive force that causes destruction with its lava flows, gases, and pyroclastic material. The volcanic activity can literary reshape the whole surrounding area and maybe even much more if it is a supervolcano in question.

what can you say about differences between men and women in the two population pyramids?

Answers

Answer:

woman's population is greater than men

In 1965, there seemed to be slightly more women than men in Germany, especially above the age of 35. By 2015, this trend had evened out somewhat, and there were slightly more men than women in a few age-groups. By and large, when you look at either 1965 or 2015 alone, there appears to be little difference between genders.

These mountains are covered with very old, dense temperate forests. Even though this range is one of the largest by area in Europe and with length of around 1,500 km, it is not one of the highest, with the highest elevation being 2,655 meters. These mountains are still not very affected by the human activity, and large portion of them remain untouched, and the fact that there's very little population on them helps a lot in their preservation. These mountains are famous for their beautiful nature, rich flora and fauna, numerous castles including the one of Dracula (Vlad the Impaler)

What drives the movement of tectonic plates?

Answers

Answer:

Convection currents

Explanation:

The tectonic plates on Earth have been formed, and have been moving ever since their formation because of the convection currents. These currents are present in the mantle layer, which is the second layer from top to bottom. The radioactive decay of elements that are found deep inside the interior of the Earth manage to melt the rocks and metals, thus creating the magma. With its slow and constant movement, the convection currents manage to bring the heat and magma to the surface. As they have already broken the Earth's surface into multiple pieces, the magma is pushed up through the cracks, or occasionally forms new ones. That causes the creation of new crust, a crust that pushes the old crust aside, resulting in plate collision and subduction in other part of the surface, so the old crust gets into the mantle gradually and gets molten. This process is responsible for all the geological activity on the planet.

Which of the following accurately describes rill erosion? A. Fast-moving water from heavy rainfall forms deep channels. B. Runoff from heavy rainfall forms narrow, shallow channels. C. Runoff removes soil and loose sediment in thin layers. D. A raindrop hits the ground and displaces the surrounding soil

Answers

Answer:

B. Runoff from heavy rainfall forms narrow, shallow channels

Explanation:

The rill erosion occurs at places that are stripped of vegetation, or do not have it naturally. The area in which this erosion occurs also has to be at a certain angle, thus it has to be a slope. When a heavy rainfall occurs, it manages to create runoff. The runoff over-saturates parts of the soil, and starts moving it downwards. As it moves it downwards, narrow, shallow channels are being formed. The water runs through this streamlets, or headcuts, moving the soil down with it, thus causing an extensive erosion of the area.

What military formation did the greek city states invent

Answers

Answer:

formation

Explanation:

The phalanx, invented by the Greek city-states, was a military formation involving hoplites armed with spears, swords, and shields standing in a tight formation. This military tactic significantly impacted Greek politics and underwent several evolutions such as Theban military reforms.

Military Formation Invented by Greek City-States

The Greek city-states are renowned for inventing a particular type of military formation known as the phalanx. This formation was a highly organized way of combat where heavily armed foot soldiers, called hoplites, stood in dense formation with each hoplite covering the man to his left with a shield. The hoplites equipped themselves with roughly seventy pounds of gear, including an eight- to ten-foot thrusting spear with an iron tip and butt, an iron sword, and bronze armor such as a helmet, cuirass, greaves, and the hoplon shield.

Hoplites were required to be free Greek citizens of their polis, able to afford their own weapons, and needed to train regularly. The effectiveness of the phalanx formation on the battlefield led to the hoplites gaining political influence, demanding better political representation which had significant impacts on Greek politics. After the Peloponnesian War, the Theban military reforms, such as longer spears and wedge formation, further evolved the phalanx with military groups like the Theban Sacred Band demonstrating notable success.

Marine terraces are landforms associated with:

a. An emergent coastline
b. A submergent coastline
c. A bay
d. An estuary
e. None of the above

Answers

Answer:

a. An emergent coastline

Explanation:

The marine terraces are landforms that are associated with emergent coastlines. These landforms can be formed in two ways, either by falling of the sea levels, or by isostatic rebound. Whichever way it is, it manages to get the landform further above and further away from the sea. The marine terraces have once been on level with the sea waters, which is why they have sharp slopes. As the sea level drops, or the land lifts up, or maybe both, the marine terrace emerges above the sea, having very steep slope from the side of the sea, but being relatively flat on top, giving rise to a beautiful and interesting geographical feature.

The indian subcontinent was partitioned into _____.

Answers

Answer:

two countries, India and Pakistan

Explanation:

After the World War II, the British Empire was economically and military exhausted, and on top of it the country had lot of repairing to do on its own soil. This made them to start granting independence to their colonies as they were no longer powerful enough to keep them and control them. India was one of those colonies. The British though decided to partition the Indian subcontinent into two countries in order to avoid conflicts if it was only one country because of the tensions between the two major religious groups, Hindus and Muslims. This resulted into the creation of two countries eventually, India and Pakistan. India was the Hindu dominated territory, Pakistan was the Muslim dominated territory. This didn't prevent the conflicts though, instead in sparked them, with lot of riots, violence, displacement, murdering of people because of their religion taking place, and the tensions are still there even in the present. As it was not enough that there were two countries formed out of one, a third one emerged later on, with Bangladesh fighting for its independence and getting it after a long and bloody conflict.

Which of the following is not a function of wetlands? A. They serve as sources of drinking water. B. They recharge groundwater supplies. C. They assist with flood control. D. They provide natural water filtration.

Answers

D. They provide natural water filtration

While wetlands can be clean, the water isn't naturally filtered.

The correct  answer is option (A). They serve as sources of drinking water is not a function of wetlands.

Wetlands are critical for a variety of ecological functions, including recharging groundwater supplies (Option B), assisting with flood control (Option C), and providing natural water filtration (Option D).

These functions are well-documented and essential for maintaining water quality and quantity, as well as for supporting biodiversity and ecosystem health.

However, wetlands themselves are not typically considered direct sources of drinking water (Option A).

While they can contribute to the overall water supply and can improve water quality through filtration, wetlands are not usually tapped directly for human drinking water supplies.

How does a convection cell in the mantle lead to volcanism at the mid-ocean ridge?

Answers

The convection cell is basically a self-contained in which there is a motion, where the hotter fluid is moving upward because of the lesser density, while the cooler fluid is moving downward because it is denser. This leads to constant circular movement of the magma in the mantle layer, and the one that moves upward is constantly creating big pressure on the crust above it, penetrating through the cracks in it or melting it and intruding. As the magma pushes upward, it manages to get through the thinner and cracked crust between the plates that move away from each other at the divergent boundary. The magma reaches the ocean floor and quickly cools off, creating new crust, and that continues constantly, with more and more magma coming out and more and more new crust pilling up, eventually creating an underwater mountain range of volcanic origin known as mid-ocean ridge.
