True

False

1

Eastern boundary currents are

cold currents

warm currents

1

Western boundary currents are

cold currents

warm currents

1

Warm western boundary currents come from

the equator

the poles

1

Cold eastern boundary currents come from

the equator

the poles

1

Downwelling often occures at

Eastern boundary currents

Western boundary currents

1

Fisheries are often set up in areas where there is

upwelling

downwelling

1

Upwelling

brings nutrient rich water up to the surface

brings oxygen rich water to the surface

1

Warm surface waters are

nutrient rich because decaying organisms are found here.

oxygen rich due to an abundance of plant life and aeration from the waves

1

Areas where downwelling occurs are

good for fishing

bad for fishing

1

Upwelling occurs often in

Eastern boundary currents

Western boundary currents

1

It would be better to set up a fishing industry on the

Eastern side of an ocean basin

Western side of an ocean basin

1

Downwelling

brings oxygen rich water and decomposing materials to the ocean floor

Cold, nutrient rich water to the ocean floor.

1

Which of the folowing leads to upwelling

Surface ocean water diverges

Winds moving the water moving toward the land/ coastline

Surface ocean water converges

Winds moving the water moving away from the land/ coastline

1

Which of the folowing leads to downwelling

Winds moving the water moving away from the land/ coastline

Surface ocean water diverges

Winds moving the water moving toward the land/ coastline

Surface ocean water converges

Which of the following best describes how temperature affects the water density ?

Warmer water is more dense than cold water

Cold water is more dense than warm water

Warm and cold water have the same density

1

Which of the following best describes how salinity affects the water density ?

Lower the salinity higher the density of water

Salinity does not affect the density of water

higher the salinity higher the density of water

The Global conveyor belt

null

1

The cold salty water at the poles will ____________________

Sink to the bottom

Stay on the top

1

The warm water at the equator moves towards poles and the cold water at the poles moves toward the equator. Why is this important

Prevents overheating of the equatorial water and over freezing of the polar water

Moves water around so it is not stagnant

Prevents the movement of the magnetic fields at the pole

1

As the cold salty water sinks at the pole the warm oxygen rich water from the equator replaces the displacing water. This warm water cools down and sinks to the bottom. Why is this important?

The warm water has more oxygen and as it sinks at the pole it increases the oxygen available at the bottom of the ocean

The cold water has more oxygen as it rise to the surface it increases the amount of oxygen available closer to the ocean surface.

The warm water has more nutrients and as it sinks at the pole it increases the nutrients available at the bottom of the ocean

The cold water has more nutrients as it rise to the surface it increases the amount of nutrients available closer to the ocean surface.

1

The cold salty nutrient rich water water sinks at the pole and moves toward the equator. As it reaches the equator the cold water warms up and rise to the surface. Why is this important?

The cold water has more oxygen as it rise to the surface it increases the amount of oxygen available closer to the ocean surface.

The warm water has more nutrients and as it sinks at the pole it increases the nutrients available at the bottom of the ocean

The warm water has more oxygen and as it sinks at the pole it increases the oxygen available at the bottom of the ocean

The cold water has more nutrients as it rise to the surface it increases the amount of nutrients available closer to the ocean surface.

1

What will happen if the temperature differences between the poles and the equator decrease?

The global conveyor belt will keep moving as it is not affected by the temperature of the oceans

The global conveyor belt will slow down and eventually stop.

The global conveyor belt will stop half way

The global conveyor belt will keep moving but the direction of the curents will reverse
