What causes movement in air?

biology physical resources air and winds wind energy air as a natural resource

  1. Difference in temperature

  2. Difference in pressure

  3. Difference in volume

  4. Both A and B

Show answer
Correct Option: D
Explanation:
Movements in the air are caused due to pressure and temperature gradient. The high temperature leads to the rising of air which creates a low-pressure region. The air from the surrounding high-pressure zone moves to low-pressure area to stabilise the pressure which creates a breeze
So, the correct answer is 'Both A and B'

The instrument which measures wind velocity is

  1. Lactometer

  2. Anemometer

  3. Hydrometer

  4. Barometer

Show answer
Correct Option: B
Explanation:

Anemometer is the instrument used to measure wind velocity. Hydrometer measures specific gravity (or relative density) of liquids. Barometer is used to measure atmospheric pressure. Lactometer measures cream content of milk.
