Hydrologic Cycle

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, and runoff.

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor, primarily occurring from bodies of water, soil, and plants.

Front

What is condensation?

Back

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

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 percentage of Earth's water is salt water?

Back

97% of the Earth's water is salt water, primarily found in oceans, making it undrinkable for humans.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water, such as rivers, lakes, and oceans.

Front

What is transpiration?

Back

Transpiration is the process by which water is absorbed by plants' roots, moves through plants, and is released as water vapor through pores in leaves.

Front

What is percolation?

Back

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

Front

What role do clouds play in the hydrologic cycle?

Back

Clouds are formed by condensation of water vapor and play a crucial role in the hydrologic cycle by storing and transporting water until it falls as precipitation.

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions in a specific place at a specific time, while climate refers to the long-term average of weather patterns in a region.
