Hydrological cycle STUDY GUIDE

Front

What is the hydrological cycle?

Back

The hydrological cycle, also known as the water cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and infiltration.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants from the soil and then released as water vapor into the atmosphere through small openings in their leaves.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is converted into water vapor, usually due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is collection in the hydrological cycle?

Back

Collection refers to the process where water gathers in bodies of water such as rivers, lakes, and oceans after precipitation.

Front

What is sublimation?

Back

Sublimation is the process where ice or snow changes directly into water vapor without first melting into water.

Front

What is deposition in the hydrological cycle?

Back

Deposition is the process where water vapor changes directly into ice or snow, bypassing the liquid state, often seen in frost formation.

Front

What percentage of the world's water is freshwater?

Back

Less than 1% of the world's water is freshwater, which is available for human use.

Front

What percentage of the world's water is in the oceans?

Back

Approximately 97% of the world's water is found in the oceans.
