Earth's Changing Climate Amplify

Ice core data from Greenland indicates there was a time period on Earth when the atmosphere changed so more energy entered the Earth system than exited. What change to the atmosphere could have caused this, and how would it have affected energy on Earth during that time?

• Carbon dioxide increased, leading to more energy in the Earth system because more exiting energy was redirected (bounced) back toward Earth.

• Carbon dioxide increased, leading to more energy in the Earth system because more energy was trapped by gases and held in the atmosphere.

• Carbon dioxide decreased, leading to less energy in the Earth system because less exiting energy was redirected (bounced) back toward Earth.

• Carbon dioxide decreased, leading to more energy in the Earth system because less energy from the sun was redirected (bounced) back toward outer space.

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 the 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 less energy entered than exited.

• There was less energy in the Earth system and less energy absorbed by Earth's surface, because more energy 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.

Scientists have tools that measure the amount of energy entering and exiting the Earth system. Recently, more energy entered the system than exited. What might scientists expect to see in the atmosphere, and what has changed about energy in the Earth system during this time?

• Methane decreased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.

• Methane decreased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

• Methane increased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.

• Methane increased, leading to less energy in the Earth system and less energy absorbed by Earth's surface.

A climatologist is creating a simulation for Earth's climate and is working on how to set it up. One of the options for the simulation is to increase methane in the atmosphere. How should the energy in the Earth system change when the amount of methane in the atmosphere increases?

There should be . .

• more energy in the Earth system and more energy absorbed by Earth’s surface, because less energy enters than exits

• more energy in the Earth system and more energy absorbed by Earth’s surface, because more energy enters than exits

• less energy in the Earth system and less energy absorbed by Earth’s surface, because more energy enters than exits

• less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy enters than exits

Scientists think that a large amount of carbon dioxide was released from rock on the ocean floor from 120 to 80 million years ago and that this led to increased carbon dioxide in the atmosphere. What happened to energy in the Earth system during this time?

• increased, because less energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more exiting energy was redirected (bounced) back toward Earth.

• increased, because more energy entered than exited. This is because more energy was trapped by gases and held in the atmosphere.

• decreased, because less energy entered than exited. This is because more energy from the sun was redirected (bounced) back toward outer space.
