Answer:
Vapour in the atmosphere condenses into water droplets or snow particles, which shower on the earth. This is called as precipitation.

Question 2.
What is called air pressure?

Answer:
The atmosphere contains vapour. The air that has greater amount of vapour is called humid air.

Give geographical reasons for the following statements:

Question 1.
As we move upward from the sea-level, temperature of the air decreases.
Answer:

• The earth’s surface gets heat from the Sun.
• Thus, the surface gets heated.
• The air close to the earth surface starts becoming hot.
• Later, different layers of air at higher elevation receive heat.
• Therefore, as we move upward from sea-level, the temperature of air decreases.

Question 2.
Air pressure decreases with increasing height.
Answer:

• The lowermost layers of air are subjected to the pressure of the upper layers.
• So, the density of the lower layers of air increases.
• There is greater air pressure near the surface of the earth.
• Therefore, air pressure decreases with increasing height.

Answer the following questions:

Question 1.
What is known as precipitation?
Answer:
Vapour in the atmosphere condenses into water droplets or snow particles. Their showering on the earth is called precipitation.

Question 2.
What is called moisture?
Answer:
The humidity in the atmosphere is called moisture. The proportion of moisture in the atmosphere depends on the temperature. Air with higher temperature holds a greater amount of moisture.
