Surface currents greatly affect the climate in many parts of the world.

Yes, currents affect the climate and temperatures.

TRUE

Explanation:

The surface currents are generated either by the wind or due to the difference in their density. The tropical and equatorial region receives the maximum amount of heat as a result of which the water gets heated up and rises up to the atmosphere forming a low-pressure zone. This heat flows from the equator to the polar region and during its motion, it is influenced by factors such as Coriolis force, density, temperature and salinity of the water.

Thus, this surface current is responsible for the regulation of the earth's global climatic condition.

Hence, the above-given statement is true.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
