What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases). Warm air rises, while cooler air sinks, creating a cycle.

Why are greenhouse gases important?

Back

Greenhouse gases trap heat in the atmosphere, which helps keep the Earth warm enough to support life. However, too many can lead to global warming.

Front

What gas has the highest percentage in our atmosphere?

Back

Nitrogen makes up about 78% of the Earth's atmosphere.

Front

Which month is typically the coldest in the Northern Hemisphere?

Back

January is usually the coldest month.

Front

What biome is characterized by very low rainfall and extreme temperatures?

Back

Desert biome is characterized by low rainfall and can have extreme temperature variations.

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.

Front

What is the role of trees in the environment?

Back

Trees absorb carbon dioxide and release oxygen, helping to regulate the atmosphere and combat climate change.

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 a climatograph?

Back

A climatograph is a graphical representation of the average temperature and precipitation in a specific area over a period of time.

Front

What is the significance of the ozone layer?

Back

The ozone layer protects the Earth from harmful ultraviolet (UV) radiation from the sun.
