What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all the water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without passing through the liquid state.
