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?
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.
Fossilized shells from the Pacific Ocean show that about 15 million years ago, there was a time period when carbon dioxide in the atmosphere increased. What would have happened to the energy absorbed by Earth’s surface during this time?
During this time, energy absorbed by Earth’s surface
stayed at a constant level.
changed unpredictably.
decreased.
increased.
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.
From about 120 to 80 million years ago, scientists think that a large amount of carbon dioxide was released from rock on the ocean floor, which 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 wasredirected (bounced) back toward outer space.
A climatologist was working with a computer simulation that models Earth’s climate and atmosphere. She set up the controls of the simulation to decrease the amount of methane in the atmosphere. What should happen to the amount of energy absorbed by Earth’s surface?
When methane decreases, the amount of energy absorbed by Earth’s surface should
change unpredictably.
stay at a constant level.
increase.
decrease.
Climate researchers are creating a computer simulation to help them understand changes In The earth system they want to use the simulation to see what happens when they increase the Carbon dioxide in the atmosphere. What should their stimulation show about energy absorbed by earths surface? When carbon dioxide in the atmosphere increases the amount of energy absorbed by Earths surface.
Increase
decrease
Stay it a constant level
Change
Which of the following gases does not trap heat?
Carbon Dioxide
Nitrogen
Water Vapor
Methane
As average global temperature rises
Average precipitation increases
Average precipitation decreases
Average precipitation is unchanged
Fossil evidence from the time of Tyrannosaurus rex (85–65 million years ago) shows less energy entered the Earth system than exited, even though energy from the sun didn’t change. How might the amount of carbon dioxide changed to cause this, and how would that have changed the energy absorbed by Earth’s surface??
Carbon dioxide decreased so there was less energy in the Earth system and less energy absorbed by Earth's surface.
Carbon dioxide decreased so there was more energy in the Earth system and more energy absorbed by Earth's surface.
Carbon dioxide increased so there was more energy in the Earth system and more energy absorbed by Earth's surface.
Carbon dioxide increased so there was less energy in the Earth system and less energy absorbed by Earth's surface.
Some kinds of pollution in the atmosphere can act to cool the planet by reducing the amount of solar radiation that reaches Earth's surface.
True
False
Earth has been warmer in the past than it is today.
True
False

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.
How does the increase in greenhouse gases like carbon dioxide and methane contribute to Earth's changing climate?
They trap more heat in the atmosphere, leading to global warming.
They reflect sunlight away from Earth, causing cooling.
They have no significant effect on Earth's climate.
They increase the Earth's albedo, reducing heat absorption.
Which of the following is a potential consequence of Earth's changing climate on global sea levels?
Sea levels will decrease due to increased evaporation.
Sea levels will remain constant as ice melts and refreezes.
Sea levels will rise due to the melting of polar ice caps and glaciers.
Sea levels will fluctuate unpredictably without any long-term trend.
What role do ocean currents play in Earth's changing climate?
They have no impact on climate change.
They distribute heat around the planet, affecting weather patterns.
They only affect marine life, not the climate.
They cause the Earth's axis to tilt, influencing climate.
