Human Impact on Climate Review

Front

What happens to energy from the Sun when it reaches Earth?

Back

Some of the energy is absorbed by land and water.

Front

What is albedo?

Back

Albedo is a measure of how much solar energy is reflected by a surface.

Front

Does a dark color have a higher or lower albedo than a light color?

Back

A dark color has a lower albedo than a light color.

Front

What is the main greenhouse gas responsible for climate change?

Back

Carbon dioxide.

Front

What effect does melting land ice have on sea levels?

Back

Melting land ice causes sea levels to rise because it adds water to the ocean.

Front

What does a higher albedo indicate about a material's reflection of solar energy?

Back

The higher the albedo of a material, the more solar energy it will reflect.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth due to the trapping of heat by greenhouse gases.

Front

Name two greenhouse gases besides carbon dioxide.

Back

Methane and nitrogen.

Front

How does deforestation impact climate change?

Back

Deforestation increases carbon dioxide levels in the atmosphere, contributing to climate change.

Front

What role do oceans play in climate regulation?

Back

Oceans absorb carbon dioxide and heat, helping to regulate Earth's climate.
