Climate Change Flashcard

Front

What is the greenhouse effect?

Back

The warming effect that occurs when gases in the Earth's atmosphere trap heat from the sun.

Front

What human activity contributes most to the increase of greenhouse gases?

Back

Burning fossil fuels.

Front

What does the greenhouse effect cause?

Back

Earth to be warm enough to support life.

Front

What is the primary cause of the greenhouse effect?

Back

Emission of greenhouse gases by human activities.

Front

What gas is released into the atmosphere when gas, oil, and coal are burned?

Back

Carbon dioxide.

Front

Define greenhouse gases.

Back

Gases in the Earth's atmosphere that trap heat, including carbon dioxide, methane, and nitrous oxide.

Front

What is the role of carbon dioxide in climate change?

Back

Carbon dioxide traps heat in the atmosphere, contributing to the greenhouse effect and global warming.

Front

How do human activities affect the greenhouse effect?

Back

Human activities, such as burning fossil fuels and deforestation, increase the concentration of greenhouse gases in the atmosphere.

Front

What is albedo?

Back

Albedo is the measure of how much sunlight is reflected by a surface; higher albedo means more reflection and less heat absorption.

Front

What is the impact of deforestation on climate change?

Back

Deforestation reduces the number of trees that absorb carbon dioxide, increasing greenhouse gas levels in the atmosphere.
