Atmosphere & Climate Change

Front

What are trace gases?

Back

Trace gases are small amounts of gases in the atmosphere, such as water vapor, carbon dioxide, methane, nitrous oxide, and CFCs, making up only 0.1% of Earth's atmosphere.

Front

What is the effect of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat, contributing to the greenhouse effect and climate change.

Front

Which human activity would NOT decrease CO2 emissions?

Back

Cutting trees in a large area to create land for a shopping mall would NOT decrease CO2 emissions.

Front

What is the composition of Earth's atmosphere?

Back

Earth's atmosphere is primarily composed of nitrogen (78%), oxygen (21%), and trace gases (1%).

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, including carbon dioxide, methane, and water vapor.

Front

How do fossil fuels impact the atmosphere?

Back

Burning fossil fuels releases carbon dioxide and other greenhouse gases, increasing their concentration in the atmosphere.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the atmosphere trap heat, keeping the Earth warm.

Front

What role do trees play in reducing CO2 levels?

Back

Trees absorb carbon dioxide during photosynthesis, helping to reduce CO2 levels in the atmosphere.

Front

What is the significance of recycling in relation to climate change?

Back

Recycling reduces waste and the need for new materials, which can lower greenhouse gas emissions associated with production.

Front

What is the impact of public transportation on CO2 emissions?

Back

Using public transportation reduces the number of vehicles on the road, leading to lower CO2 emissions compared to individual car use.
