What is the hydrologic cycle?

Back

The hydrologic 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, infiltration, and runoff.

What is permeability?

Back

Permeability is the ability of a material, such as rock or sediment, to allow fluids (like water) to pass through it. It is a key factor in determining how water moves through the ground.

What is infiltration?

Back

Infiltration is the process by which water soaks into the ground after precipitation occurs. It is crucial for recharging groundwater supplies.

Front

What is condensation?

Back

Condensation is the process by which water vapor in the air cools and changes into liquid water, forming clouds. It is a key step in the hydrologic cycle.

Front

What is transpiration?

Back

Transpiration is the process by which plants release water vapor into the atmosphere as a waste product. It contributes to the water cycle by returning water to the air.

Front

What is evaporation?

Back

Evaporation is the process by which liquid water is transformed into water vapor, usually due to heat from the sun. It is the first step in the hydrologic cycle.

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 runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and eventually returns to rivers, lakes, and oceans. It is an important part of the water cycle.

Front

What is percolation?

Back

Percolation is the process by which water moves downward through soil and rock layers, filtering through the material and replenishing groundwater.

Front

What is the role of the sun in the hydrologic cycle?

Back

The sun provides the energy necessary for evaporation to occur, driving the entire hydrologic cycle by transforming liquid water into vapor.
