Imagine Grandpa owns a large piece of land. He decides to clear the entire area of trees to make space for a new farm. What is the likely impact of this action on climate change?

• It decreases the amount of carbon dioxide in the atmosphere

• It increases the Earth's albedo

• It increases the amount of carbon dioxide in the atmosphere

• It has no significant impact on climate change

What role do oceans play in climate change?

• Oceans store and distribute solar energy, affecting global climate patterns.

• Oceans produce greenhouse gases that contribute to climate change.

• Oceans reflect sunlight, significantly cooling the Earth.

• Oceans absorb all excess CO2, preventing climate change.

During a family discussion, Grandpa explains to Dad the role of oceans in climate change. What does he likely say?

• They produce the majority of greenhouse gases

• They absorb a significant amount of Earth's carbon dioxide

• They reflect sunlight back into space

• They are not affected by climate change

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.

How does climate change amplify the greenhouse effect?

• By increasing the concentration of greenhouse gases in the atmosphere

• By decreasing the concentration of greenhouse gases in the atmosphere

• By reducing the Earth's albedo

• By increasing the Earth's albedo

What is the impact of permafrost melting on climate change?

• It releases methane, a potent greenhouse gas, amplifying climate change

• It absorbs carbon dioxide, reducing climate change

• It increases the Earth's albedo, cooling the planet

• It has no impact on climate change
