Oceanography: Surface Currents

The video explains ocean currents, focusing on surface currents driven by wind. It describes how these currents move water horizontally and introduces gyres. The Gulf Stream is highlighted as a significant current affecting climate and aiding sailors.

What is the primary force that drives surface currents in the ocean?

• Sunlight

• Wind

• Tides

• Earth's rotation

How do surface currents generally move water?

• In a spiral motion

• In a zigzag pattern

• Horizontally, parallel to the Earth's surface

• Vertically, from the ocean floor to the surface

What are gyres?

• Deep-sea trenches

• Circular patterns of ocean currents

• Large oceanic whirlpools

• Underwater volcanoes

Which ocean current is known for flowing along the East Coast of North America?

• Kuroshio Current

• California Current

• Gulf Stream

• Benguela Current

How does the Gulf Stream affect the climate of northern countries like Ireland and England?

• It cools the climate significantly

• It causes frequent storms

• It has no impact on the climate

• It brings warm water and moderates the climate
