Atmosphere, Climate Change and Human Impact

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat. They include carbon dioxide, methane, nitrous oxide, and water vapor.

What is the most abundant gas in Earth's atmosphere?

Back

Nitrogen is the most abundant gas in Earth's atmosphere, making up about 78% of it.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases that surrounds the Earth, providing air for living organisms and protecting the planet from harmful solar radiation.

Front

How is carbon stored in the environment?

Back

Carbon is stored in trees and other living things, oceans, underground in soil, and fossil fuels.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the atmosphere trap heat from the sun, keeping the Earth's surface warm.

Front

What role do trees play in carbon storage?

Back

Trees absorb carbon dioxide from the atmosphere during photosynthesis, storing carbon in their biomass.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, largely driven by human activities.

Front

What human activities contribute to climate change?

Back

Human activities such as burning fossil fuels, deforestation, and industrial processes release greenhouse gases into the atmosphere.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.

Front

What is the ozone layer?

Back

The ozone layer is a region of Earth's stratosphere that contains a high concentration of ozone (O3) and protects the planet from harmful ultraviolet (UV) radiation.
