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.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
