Question

3. What will happen if.....
(a) The amount of water vapour in the
air increases.
(b) Only one crop is grown repeatedly
in the soil.​

Answer 1

Answer:

a) If the amount of water vapor in the air increases, the relative humidity increases, and vice versa. ... If the water vapor content stays the same and the temperature drops, the relative humidity increases. If the water vapor content stays the same and the temperature rises, the relative humidity decreases.

b) If  only one crop is grown rapidly in a soil the soil will lose all its nutrients and we won't be able to grow more crops in it.. The soil will also get nitrogen deficiency and no crops will be able to get proper nutrients to grow.
