Greenhouse effect

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

How do greenhouse gases contribute to the greenhouse effect?

Back

Greenhouse gases absorb and emit infrared radiation, which leads to the warming of the Earth's surface and atmosphere.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What is the primary cause of global warming?

Back

The primary cause of global warming is the increase in greenhouse gases due to human activities, such as burning fossil fuels and deforestation.

Front

How does burning fossil fuels contribute to global warming?

Back

Burning fossil fuels releases carbon dioxide and other greenhouse gases into the atmosphere, which enhances the greenhouse effect and leads to global warming.

Front

What is the relationship between global warming and sea level rise?

Back

Global warming causes glaciers and ice caps to melt, contributing to rising sea levels.

Front

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

Back

Oxygen is the second most abundant gas in the Earth's atmosphere, after nitrogen.

Front

What role do glaciers and ice caps play in the Earth's climate system?

Back

Glaciers and ice caps reflect sunlight and help regulate the Earth's temperature; their melting due to global warming contributes to sea level rise.

Front

What are some effects of global warming on the environment?

Back

Effects of global warming include increased temperatures, rising sea levels, more extreme weather events, and changes in ecosystems.

Front

What is the significance of the carbon cycle in relation to greenhouse gases?

Back

The carbon cycle is crucial for regulating the amount of carbon dioxide in the atmosphere, which affects the greenhouse effect and global warming.
