U3L1 Hydrosphere (1st attempt)

Front

What is the hydrosphere?

Back

The hydrosphere is the combined mass of water found on, under, and above the surface of a planet, including oceans, rivers, lakes, groundwater, and water vapor in the atmosphere.

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes such as evaporation, condensation, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor, usually due to heat from the sun.

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.

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 a watershed?

Back

A watershed is an area of land that drains rainwater and snowmelt into a common water body, such as a river, lake, or ocean.

Front

What are aquifers?

Back

Aquifers are underground layers of water-bearing rock or sediment that store groundwater and can supply wells and springs.

Front

What is runoff?

Back

Runoff is the flow of water, from rain or melting snow, that moves across the ground and eventually enters rivers, lakes, and oceans.

Front

What is the difference between surface water and groundwater?

Back

Surface water is found in bodies of water like rivers and lakes, while groundwater is water that is stored underground in aquifers.

Front

What is the role of plants in the water cycle?

Back

Plants play a role in the water cycle through a process called transpiration, where they release water vapor into the atmosphere.
