Hydrosphere Review

Front

Where is the majority of Earth's freshwater located?

Back

The majority of Earth's freshwater is located in polar ice caps.

Front

How can the atmosphere be considered part of the hydrosphere?

Back

The atmosphere is considered part of the hydrosphere because it is a source of water.

Front

What property of water allows some insects to walk across the surface of a lake?

Back

Water is a polar molecule, and its cohesiveness causes high surface tension.

Front

What ocean condition is most responsible for an increase in shark population near the surface?

Back

Upwelling is the ocean condition most responsible for an increase in shark population near the surface.

Front

What is an estuary?

Back

An estuary is a semi-enclosed area where fresh water from a river meets salty water from the sea.

Front

What is the hydrosphere?

Back

The hydrosphere includes all the water on Earth, including oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the role of the polar ice caps in the hydrosphere?

Back

The polar ice caps store a significant amount of Earth's freshwater.

Front

How does water's polarity affect its properties?

Back

Water's polarity leads to its unique properties, such as high surface tension and the ability to dissolve many substances.

Front

What is upwelling in oceanography?

Back

Upwelling is the process where deep, cold water rises to the surface, bringing nutrients that support marine life.

Front

What is the significance of salinity in ocean water?

Back

Salinity affects the density of ocean water, which influences ocean currents and marine ecosystems.
