Question

What is the climate in coastal plains?
What is the climate in river plains?
What is the reason of the coldness in mountains?

Answer 1

Explanation:

The climate of the Coastal Plain is mild, with hot summers and cool winters with few hard freezes. Precipitation is high, particularly along the coast, and seasonal.

Answer 2

Here is your answer.

1. Coastal areas have moderate temperature because the land absorbs and radiates heat much faster than sea. So, during the day cool air from sea rush towards the land and during night cool air from the land rush towards sea.
2. The Ganges basin encompasses some 419,300 square miles (1,086,000 square km) and contains the largest river system on the subcontinent. The water supply depends partly on the rains brought by the southwesterly monsoon winds from July to October as well as on the flow from melting Himalayan snows in the hot season from April to June. Precipitation in the river basin accompanies the southwest monsoon winds, but it also comes with tropical cyclones that originate in the Bay of Bengal between June and October. Only a small amount of rainfall occurs in December and January. The average annual rainfall varies from 30 inches (760 mm) at the western end of the basin to more than 90 inches (2,290 mm) at the eastern end. (In the upper Gangetic Plain in Uttar Pradesh, rainfall averages about 30–40 inches [760–1,020 mm]; in the Middle Ganges Plain of Bihar, from 40 to 60 inches [1,020 to 1,520 mm]; and in the delta region, between 60 and 100 inches [1,520 and 2,540 mm].) The delta region experiences strong cyclonic storms both before the commencement of the monsoon season, from March to May, and at the end of it, from September to October. Some of those storms result in much loss of life and the destruction of homes, crops, and livestock. One such storm, which occurred in November 1970, was of catastrophic proportions, resulting in deaths of at least 200,000 and possibly as many as 500,000 people; another, in April 1991, killed some 140,000.
3. As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level.
