Long Answer type Questions:- 

Q1. Explain the factors responsible for the changes in atmospheric pressure on the earth's surface.

Ans. The factors responsible for the change in atmospheric pressure on the earth's surface are as follows:-

- Unequal heating of the earth- Different parts of the earth receives different level of insolation, which depends upon distance from the equator, when we move towards poles then the amount of radiation received by earth surface decreases in both hemisphere.

- Deflection of wind- due to earth rotation pressure belts are also affected and the earth is divided into seven pressure belts.

Q2. Describe the main features of planetary winds.

Ans. The main features of planetary winds are as follows:-

    - The amount of moisture is almost zero in the cold air of the polar region during the winter months.

Q4. Name and explain the various types of rainfall.

Ans. The various types of rainfall are as follows:-

        - Convectional Rainfall- Air gets heated after coming in contact with earth and becomes lighter. It rises up and become cooler with increase in height, which leads to condensation and formation of cumulus clouds, these clouds cause rainfall with thunder and lightning. Such type of rainfall is experienced every near the equator.

        - Orographic rainfall- When the moist air ascend along the slop of any mountain, then it leads to condensation and formation of clouds and cause rainfall. Such type of rainfall is experienced in areas near the mountains.

        - Cyclonic Rainfall- Cyclones are formed in warm sea, the air present here creates low pressure and cold wind blow towards these areas, when cold and warm wind comes in contact the lighter warm wind rides the cold wind, which increase the height of the warm air and condensation takes place in the warm air and rainfall takes place in along the path of cyclone.
