How does the Coriolis effect influence moving objects?

• a) It causes objects to move in a straight line.

• b) It causes objects to move from east to west.

• c) It causes objects to move to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

• d) It causes objects to move to the left in the Northern Hemisphere and to the right in the Southern Hemisphere.

What global atmospheric circulation patterns exist?

• a) El Niño and La Niña

• b) Hadley, Ferrel, and Polar cells

How do ocean currents influence global weather phenomena and climate patterns?

• a) They have no impact on weather and climate.

• b) They only influence ocean temperatures.

• c) They redistribute heat and moisture, affecting weather and climate patterns.

• d) They cause hurricanes and typhoons.

Can power from wind be harnessed as a source of energy?

• a) True

• b) False

How are ocean currents measured?

• a) By using satellites only

• b) By using GPS devices only

• c) By using drifters and buoys

• d) By using submarines only

What creates ocean surface currents and how are they organized?

• a) Ocean tides create surface currents, which are organized based on water depth.

• b) Wind creates surface currents, which are organized based on water temperature.

• c) Earth's rotation creates surface currents, which are organized based on water density.

• d) Earth's rotation creates surface currents, which are organized based on wind patterns.

What causes upwelling and downwelling?

• a) Changes in Earth's magnetic field

• b) Ocean tides

• c) Changes in wind patterns

• d) Changes in water density

What are the main surface circulation patterns in each ocean?

• a) Polar and Equatorial currents

• b) North and South currents

• c) Western and Eastern boundary currents

• d) Deep and Shallow currents
