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
