Answer 1

Answer:

a) The Hydrologic Cycle (also called the Water Cycle) is the continuous movement of water in the air, on the surface of and below the Earth. ... When water condenses, it releases energy and warms the environment. When water evaporates it takes energy from the surrounding environment, dropping temperatures.

b)Characteristics of Atlantic Ocean :-

• The volume of Atlantic Ocean water in each bivariate class with potential-temperature range of 0·5 C and salinity range of 0·1 per mille has been estimated from 105 uniformly distributed hydrographic stations.

• The resulting statistics are presented on a pair of characteristic diagrams, each having potential temperature and salinity as co-ordinates, potential specific-volume anomaly being represented by isopleths.

c)The air we breathe: The ocean produces over half of the world's oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth's surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.

d)The marginal seas in geography and oceanography context include not only the marginal seas in geological context but also their continental margins, as well as other semi-enclosed seas such as the Arabian Sea, Baltic Sea, Bay of Bengal, Bering Sea, Beaufort Sea, Black Sea, Gulf of Mexico, the Mediterranean Sea, Red Sea ...

e)Here are the few major causes of water pollution: Sewage And Waste Water: Sewage, garbage and liquid waste of households, agricultural lands and factories are discharged into lakes and rivers. These wastes contain harmful chemicals and toxins which make the water poisonous for aquatic animals and plants.
