Water Cycle

Front

What is the water cycle?

Back

The water cycle, also known as the hydrologic cycle, is the continuous movement of water from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, precipitation, and infiltration.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) 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 infiltration?

Back

Infiltration is the process by which water on the ground surface enters the soil, replenishing groundwater supplies.

Front

What is a well?

Back

A well is a man-made hole drilled into the water table to obtain water for human use.

Front

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, serving as a source of groundwater.

Front

What is the largest reservoir of water on Earth?

Back

The largest reservoir of water on Earth is the ocean, which contains about 97% of the planet's water.

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.

Front

What is the role of human activities in water pollution?

Back

Most water pollution is the result of human activities, such as industrial discharge, agricultural runoff, and improper waste disposal.
