Hydrological Cycle

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 includes processes such as evaporation, condensation, precipitation, and runoff.

What is an aquifer?

Back

An aquifer is a layer of rock or sediment that holds water and can supply water to wells and springs.

What role does temperature play in the water cycle?

Back

Temperature affects the state of water, causing it to change between solid (ice), liquid (water), and gas (water vapor), which drives the processes of evaporation and condensation.

What is fresh water?

Back

Fresh water is the type of water that is safe for drinking and is found in sources like rain, lakes, rivers, and aquifers.

Front

What is runoff?

Back

Runoff occurs when water does not infiltrate the ground but flows across the land, contributing to surface water.

Front

What is non-point source pollution?

Back

Non-point source pollution is pollution that comes from many different places and is hard to identify its source, such as runoff from agricultural fields.

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 evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) due to heat.

Front

What is condensation?

Back

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