Earth Science A Unit 3 quiz

Part of the sun’s energy that strikes the surface is used by plants in the process of photosynthesis. Why is this process important to the earth’s systems?

• It is a heat-producing process whereby plants keep the earth warmer than normal.

• It increases the energy in the atmosphere to increase the power of storms, which bring rain and snow to water the land.

• It is a major greenhouse gas factor, since photosynthesis returns carbon dioxide back to the atmosphere.

• It is used to convert carbon dioxide and water into food for the biosphere, thereby removing carbon dioxide from the atmosphere

What must happen to plant and animal matter in order for it to be turned into fossil fuels like coal, oil, and natural gas?

• It must be altered by natural radioactivity from the earth’s core.

• It must be buried for millions of years under high heat and pressure.

• It has to completely decay into simple molecules and then be reformed by bacteria.

• It must undergo fossilization—turning into stone.

One kilogram of water will absorb about how many times the energy of one kilogram of soil?

• 4000

• 10

• 4

• 2

Which part of the earth experiences the most extreme (widest range in) temperature changes?

• oceans

• land-deserts

• ice caps

• coastal regions

The earth has had a stable temperature for a very long time. Why is this?

• The amount of energy the earth receives from the sun is greater than the amount of energy that escapes back into space.

• The amount of energy the earth receives from the sun is less than the amount of energy that escapes back into space.

  message

• The amount of energy the earth receives from the sun is equal to the amount of energy that escapes back into space.

What would happen to the temperature of a planet if the amount of energy escaping into space were less than the energy it received from the sun?

• The planet would cool down.

• The planet would not change.
