The Earth System

What will happen to the water in a reservoir if people use more water, so that the flow out becomes greater than the flow in?

• The amount of water in the reservoir will increase, and may overflow.

• The amount of water in the reservoir will decrease, and may eventually run out.

• equinox

• rotation

• solstice

An equinox occurs when

• the Earth's rotation axis is tilted directly toward or away from the Sun

• when the Earth spins around its axis.

• the Earth orbits around the Sun.

• when the Earth's rotation axis is tilted neither toward nor away from the Sun.

Climate researchers in Greenland can use ice core samples to tell them about methane in the atmosphere in the past. Researchers found a sample that showed a time period when methane in the atmosphere increased. What happened to amount of energy absorbed by Earth's surface during this time?

During this time, the amount of energy absorbed by Earth’s surface

• stayed at a constant level.

• changed unpredictably.

• increased.

• decreased.

Geologists have found rocks showing that about 700 million years ago, there was a time period when the amount of carbon dioxide in the atmosphere decreased. How did energy in the Earth system change during this time?

• There was more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy entered than exited.

• There was more energy in the Earth system and more energy absorbed by Earth’s surface, because lessenergy entered than exited.

• There was less energy in the Earth system and less energy absorbed by Earth’s surface, because moreenergy entered than exited.

• There was less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy entered than exited.

There are some bacteria that release methane into the atmosphere. Scientists think that if the number of these bacteria decreased, the amount of methane in the atmosphere would decrease. What would happen to energy in the Earth system if the atmosphere had less methane?Energy in the Earth system would

• decrease, because less energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.

• decrease, because more energy would enter than exit. This is because less exiting energy would beredirected (bounced) back toward Earth.

• decrease, because less energy would enter than exit. This is because less energy would be trapped by gases and held in the atmosphere.

• increase, because more energy would enter than exit. This is because less energy from the sun would beredirected (bounced) back toward outer space.
