Ocean Currents and their Characteristics
The given question is related to ocean currents and their characteristics. Let us analyze each pair mentioned in the question and determine whether they are correctly matched or not.
1. Labrador Current: Cold
The Labrador Current is a cold ocean current that flows along the coast of Labrador and Newfoundland in Canada. It originates from the Arctic region and carries cold water southward towards the Gulf of St. Lawrence. This current is indeed characterized by its low temperature, making the first pair correctly matched.
2. Kuroshio Current: Warm
The Kuroshio Current is a warm ocean current that flows along the eastern coast of Japan. It is a continuation of the North Pacific Current and brings warm water from the tropics into the region. The Kuroshio Current is known for its high temperature, supporting diverse marine life and influencing the climate of the surrounding areas. Therefore, the second pair is also correctly matched.
3. Canaries Current: Warm
The Canaries Current, also known as the Canary Current, is a cold ocean current that flows southward along the northwest coast of Africa. It is a part of the Atlantic Meridional Overturning Circulation and is characterized by its lower temperature. Hence, the third pair is incorrectly matched.
Conclusion
Based on the analysis, we can conclude that pair 1 and 2 is correctly matched, while pair 3 is incorrectly matched. Therefore, the correct option is B) 1 and 2 only.

Consider the following pairs: Ocean Currents Characteristic1. Labrador...
The ocean currents may be classified based on their depth as surface currents and deep water currents :
- Surface currents constitute about 10 per cent of all the water in the ocean, these waters are the upper 400 m of the ocean.
- Deep water currents make up the other 90 per cent of the ocean water. These waters move around the ocean basins due to variations in the density and gravity. Deep waters sink into the deep ocean basins at high latitudes, where the temperatures are cold enough to cause the density to increase.
Ocean currents can also be classified based on temperature as cold currents and warm currents:
1. Cold current:
- It brings cold water into warm water areas. These currents are usually found on the west coast of the continents in the low and middle latitudes (true in both hemispheres) and on the east coast in the higher latitudes in the Northern Hemisphere.
2. Warm currents:
- It brings warm water into cold water areas and are usually observed on the east coast of continents in the low and middle latitudes (true in both hemispheres). In the northern hemisphere they are found on the west coasts of continents in high latitudes.
3. Labrador Current:
- This current drifts south-eastwards between West Greenland and Baffin Island of Canada. This current meets the warm Gulf Stream off Newfoundland of Canada.
- It is a cold current.
4. Canaries Current:
- It flows southwards along the coasts of Europe and Africa, to finally merge with the North Equatorial Current. Since it receives water from the polar regions, it is a cold current.
5. Kuroshio Current:
- The North Equatorial Current under the influence of the North-east Tradewinds flows off the coasts of Philippines and Formosa as the Kuroshio current in the East China Sea. This is also known as Kuru Siwo or Japan Current.
- Most of it lies in the subtropical high-pressure belt and is under the influence of the westerlies.
- Since it carries the equatorial waters, it is a Warm current.
Hence option (b) is the correct answer.
