Question

Study the map and answer the following questions.

1. What are the major types of ocean currents?
2. What do you call the currents flowing from the equator to the poles?
3. What do you call the currents flowing from the poles to the equator?
4. When the currents are moving in a circular manner, what difference is visible in their direction in Northern and Southern Hemisphere respectively?
5. What might happen at the places where these currents meet?
6. When two different types of currents meet along the coast then what type of human settlements and occupations are seen.

Answer 1

1. The major types of ocean currents are warm currents and cold currents. Warm currents flow from the equator towards the poles, while cold currents flow from the poles towards the equator.
2. They are called warm currents.
3. They are called cold currents.
4. They flow clockwise in the Northern Hemisphere and anticlockwise in the Southern Hemisphere.
5. Where warm and cold currents meet, plankton and other marine vegetation grow, attracting many fish. Dense fog may also form.
6. These areas often develop fishing settlements and fishing occupations because the abundant plankton attracts large numbers of fish and creates major fishing grounds.
