Earth's Changing Climate Review

Front

What happens to Earth's energy absorption when greenhouse gases increase?

Back

The amount of energy the Earth absorbs increases.

Front

What is the effect on energy absorption if methane levels decrease?

Back

The amount of energy absorbed by Earth's surface would decrease.

Front

What occurs to energy in the Earth system if carbon dioxide levels decrease?

Back

Energy will decrease, because less energy entered than exited.

Front

How does an increase in carbon dioxide affect Earth's energy absorption?

Back

The amount of energy Earth absorbs increases.

Front

What is the primary cause of Earth's rising temperature?

Back

Climate change.

Front

Define greenhouse gases.

Back

Gases in the atmosphere that trap heat, contributing to the greenhouse effect.

Front

What is the greenhouse effect?

Back

The process by which greenhouse gases trap heat in the atmosphere, warming the Earth.

Front

Name a major greenhouse gas other than carbon dioxide.

Back

Methane.

Front

How do human activities contribute to climate change?

Back

By increasing greenhouse gas emissions through burning fossil fuels, deforestation, and industrial processes.

Front

What is the role of carbon dioxide in the atmosphere?

Back

It helps regulate Earth's temperature by trapping heat.
