Write short notes on given topics.

Question 12 Marks

Deep ocean currents.

Answer

Deep ocean currents leads to transfer of warm water to the bottom from the surface and cold water to the surface from the bottom.
Deep ocean currents thus leads to redistribution of sea water.

Question 22 Marks

The transportation capacity of ocean currents.

Answer

The transportation capacity of ocean currents alters the amount of precipitation and temperature in the coastal regions along with which they flow.
The transportation capacity of ocean currents leads to transfer of warm water to the bottom from the surface and cold water to the surface from the bottom.

Question 32 Marks

Meeting of warm and cold ocean currents.

Answer

Dense fog is found in the meeting point of warm and cold ocean currents. Algae, plankton, etc. fish food grow on a large scale in these areas.
Fish come in these areas on a large scale and breed. Therefore, extensive fishing grounds are found in the areas where warm and cold ocean currents meet.

Question 42 Marks

The shape of the coastline on ocean currents.

Answer

The extended parts of coastline acts as an obstacle for ocean currents.
The extended parts of coastline alters the direction and velocity of ocean currents.

Question 52 Marks

Cold ocean currents on the movement of icebergs.

Answer

Question 62 Marks

Warm ocean currents on climate.

Answer

The amount of precipitation increases in the coastal region along with which the warm ocean currents flow.
Similarly, the temperature increases in the coastal region along with which the warm ocean currents flow.

Question 72 Marks

Cold ocean currents on climate.

Answer

The amount of precipitation decreases in the coastal region along with which the cold ocean currents flow.
Similarly, the temperature decreases in the coastal region along with which the cold ocean currents flow.
