Ocean Currents and Climate Effects

The video tutorial covers ocean circulation, focusing on currents, El Nino, and La Nina events. It explains how currents influence climate and sea life, with examples like the Gulf Stream. The Coriolis effect's role in current movement is discussed, along with the impact of ocean currents on Norway's climate. The formation of deep ocean currents due to temperature and salinity changes is also explored.

What is one of the primary roles of ocean currents in the environment?

• They control the climate.

• They prevent earthquakes.

• They produce oxygen.

• They create new landforms.

Which current is responsible for bringing warm water from Mexico to the eastern side of North America?

• The Labrador Current

• The Gulf Stream

• The California Current

• The Canary Current

How often do El Nino events typically occur?

• Every 3 to 4 years

• Every year

• Every 20 years

• Every 10 years

Which ocean do El Nino and La Nina events primarily affect?

• The Indian Ocean

• The Atlantic Ocean

• The Pacific Ocean

• The Arctic Ocean

What is the primary effect of the Coriolis effect on ocean currents in the Northern Hemisphere?

• Currents curve to the right.

• Currents curve to the left.

• Currents move in a straight line.

• Currents stop moving.

Why do cities on the western coast of Norway have a milder climate compared to inland areas?

• Due to the North Atlantic Drift

• Because of the Gulf Stream

• Because of the California Current

• Due to the Canary Current

What is the effect of the Coriolis effect on ocean currents in the Southern Hemisphere?

• Currents curve to the right.

• Currents curve to the left.

• Currents stop moving.

• Currents move in a straight line.

What happens to ocean water as it moves towards the poles?

• It remains unchanged.

• It evaporates completely.

• It becomes colder and more salty.

• It becomes warmer and less salty.

What causes deep ocean currents to form?

• The movement of tectonic plates

• The presence of marine life

• The gravitational pull of the moon

• Variations in water temperature and salinity

What happens to cold, salty water in the ocean?

• It rises to the surface.

• It evaporates quickly.

• It sinks and forms deep water currents.

• It becomes less dense.
