Hydrosphere Review Pt 2

Surface currents are a result of

• Global Wind Patterns

• Earth's Rotation

• Density

• All of the above

The Coriolis Effect is caused by

• Earth rotating around the sun

• Earth rotating on its axis

• The tides

• Gravity

Constantly moving system of deep-ocean circulation driven by temperature and salinity. It moves water around the globe.

• California Current

• Global Conveyor Belt

• Surface Currents

• Gulf Stream

The movement of deep, cold, nutrient filled water to the surface of the ocean is..

• Ocean Current

• Upwelling

• Deep Currents

• Surface Currents

What affects the density of water?

• Salt

• Temperature

• The seasons of the year

• Both A and B

Why is upwelling important?

• Upwelling regulates ocean temperature

• Upwelling provides nutrient rich water that sustains life

• Upwelling controls the tides

• Upwelling helps sailors to navigate the seas

The Gulf Stream carries warm water to the North Atlantic Ocean, which contributes to

• a mild climate for the British Isles.

• a harsh winter in the British Isles.

• a cold-water surface current that flows to the British Isles.

• a warm-water surface current that flows along the coast of California.

Ocean currents move energy in the form of

• Salt

• Water

• Heat

• Oxygen

Plants and animals that live on the ocean floor are...

• benthos

• nekton

• plankton

• diatoms

In what zone does approximately 90% of all ocean life live?

• sunlight

• twilight

• midnight
