Here are 10 one-word answer type questions on Ocean Currents, along with their answers and explanations:
1. What are the streams of water flowing constantly on the ocean surface in definite directions called?
Answer: Ocean currents
Explanation: Ocean currents are continuous movements of ocean water that flow in a particular direction due to various forces such as wind, Earth’s rotation, and temperature differences .
2. Which type of ocean currents originate near the equator and move towards the poles?
Answer: Warm currents
Explanation: Warm currents carry warm water from the equator toward higher latitudes, influencing climate and marine life .
3. Which type of ocean currents carry cold water from polar or higher latitudes to tropical or lower latitudes?
Answer: Cold currents
Explanation: Cold currents transport cooler waters from polar regions toward the equator, affecting the temperature and weather patterns of coastal areas .
4. Which ocean current is a warm current in the Atlantic Ocean?
Answer: Gulf Stream
Explanation: The Gulf Stream is a powerful warm current that originates in the Gulf of Mexico and moves toward the North Atlantic, moderating the climate of Western Europe .
5. Which cold ocean current flows near the eastern coast of Canada?
Answer: Labrador Current
Explanation: The Labrador Current is a cold current that brings icy waters from the Arctic, significantly impacting the weather and marine life in the North Atlantic .
6. What is the meeting point of warm and cold currents called?
Answer: Convergence
Explanation: When warm and cold currents meet, they create zones of high marine productivity, making them some of the world’s richest fishing grounds .
7. Which ocean region is known for frequent fog due to the meeting of warm and cold currents?
Answer: Grand Banks
Explanation: The Grand Banks off the coast of Newfoundland is a famous fishing ground where the warm Gulf Stream and cold Labrador Current meet, causing thick fog .
8. Which factor influences the direction of ocean currents due to Earth’s rotation?
Answer: Coriolis effect
Explanation: The Coriolis effect causes ocean currents to deflect to the right in the Northern Hemisphere and to the left in the Southern Hemisphere due to Earth’s rotation .
9. Which oceanic process transfers heat energy from the equator to the poles?
Answer: Thermohaline circulation
Explanation: Thermohaline circulation, also known as the global conveyor belt, moves warm and cold water across the world’s oceans, regulating climate patterns .
10. Which ocean current affects the Indian monsoon by changing sea surface temperatures in the Pacific Ocean?
Answer: El Niño
Explanation: El Niño is a climate phenomenon caused by changes in Pacific Ocean currents, leading to altered weather patterns, including weak monsoons in India .
These questions summarize key concepts of ocean currents, including their formation, movement, and effects on climate and marine life.
