What is one essential characteristic of Earth that supports life?

Back

Earth has abundant available water, which is essential for all known forms of life.

Front

How does Earth's rotation affect life?

Back

Earth rotates on its axis once every 24 hours, creating day and night cycles that influence climate and ecosystems.

Front

Front

What happens to surface water if a planet is too far from the Sun?

Back

If a planet is too far from the Sun, the surface water may freeze due to low temperatures.

Front

What is the significance of liquid water for life?

Back
