Climate Change

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's atmosphere caused by the trapping of heat that is radiated from the Earth's surface. This occurs when greenhouse gases, such as carbon dioxide, methane, and water vapor, absorb and re-radiate heat.

Front

Is the amount of carbon dioxide (CO2) in the atmosphere increasing or decreasing?

Back

False. The amount of carbon dioxide (CO2) in the atmosphere is increasing due to human activities such as burning fossil fuels.

Front

Where is carbon stored in the environment?

Back

Carbon is stored in various places including trees and other living organisms, oceans, underground in soil, and fossil fuels.

Front

What is the main human activity that releases greenhouse gases?

Back

The main human activity that releases greenhouse gases is burning fossil fuels, such as coal, oil, and natural gas.

Front

Which of the following is NOT a way to decrease your ecological footprint?

Back

Using cars for short journeys is NOT a way to decrease your ecological footprint.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat. They include carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time. While climate change is a natural phenomenon, human activities have accelerated it.

Front

How does deforestation contribute to climate change?

Back

Deforestation contributes to climate change by reducing the number of trees that can absorb carbon dioxide (CO2), leading to higher levels of CO2 in the atmosphere.

Front

What is an ecological footprint?

Back

An ecological footprint measures the environmental impact of an individual or community, expressed as the amount of land and water area required to produce the resources consumed and absorb the waste generated.

Front

What role do oceans play in climate regulation?

Back

Oceans play a crucial role in climate regulation by absorbing carbon dioxide (CO2) from the atmosphere and storing heat, which helps to moderate global temperatures.
