What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Examples include carbon dioxide, methane, and water vapor.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns and averages of weather in a particular area.

Front

What can organisms that do not decompose become when buried?

Back

They can become fossil fuels, which are natural substances formed from the remains of ancient organisms.

Front

What happens to carbon when humans burn fossil fuels?

Back

Most of the carbon quickly enters the atmosphere as carbon dioxide.

Front

Is it true that all radiation from the Sun is absorbed by the Earth?

Back

False. Not all radiation from the Sun is absorbed; some is reflected back into space.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, keeping the planet warm enough to support life.

Front

Name three major greenhouse gases.

Back

Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What role do fossil fuels play in climate change?

Back

Fossil fuels release carbon dioxide and other greenhouse gases when burned, contributing to global warming and climate change.

Front

How does deforestation affect the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, increasing the amount of CO2 in the atmosphere.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate and supporting life by recycling carbon among the atmosphere, land, and oceans.
