Why do hurricanes weaken when they move from ocean to land?

Back

Hurricanes obtain their energy from warm ocean water, and when they move over land, they lose this energy source.

Front

What is the hydrosphere?

Back

Front

What role does carbon dioxide play in Earth's atmosphere?

Back

Carbon dioxide helps to trap heat in the atmosphere, keeping Earth's surface warm.

Front

What happens to Earth's average temperature if carbon dioxide levels decrease significantly?

Back

If carbon dioxide levels in the upper atmosphere decrease, the average temperature of Earth would likely decrease.

Front

What is the difference between observational and experimental investigations?

Back

Observational investigations involve watching and recording data without manipulation, while experimental investigations involve testing hypotheses through controlled experiments.

Front

What is the cryosphere?

Back

The cryosphere is the frozen water part of the Earth system, including ice caps, glaciers, and sea ice.
