Answers
Explanation:
1 The factors responsible for the changes in atmosphere pressure on the earth's surface are: - Thus atmosphere pressure decreases with increase in temperature and increases with decrease in temperature.
2 The main features of planetary wind are polar winds, westerlies and trade winds. Explanation: Planetary wind refers to those wind that blows from one latitude to another and which are controlled by the factors such as changes in the temperature and pressure, Coriolis effect.
3 The amount of moisture present in the air varies from place to place and from time to time: ... The amount of moisture decrease with the increase in height above the mean sea level. The amount of moisture is almost zero in the cold air of the polar regions during the winter months
4The types of rainfall based on intensity can be classified as: Light rain – Rate of rain varies between 0 to 2.5 millimeters. Moderate rain – Rate of rain varies between 2.6 millimeters to 7.6 millimeters. Heavy rain – Rate of rain is beyond 7.6 millimeters.
