Solution

The correct option is A Convectional rainfall
Explanation:

Option (a) is correct because the convectional rainfall occurs due to the thermal convection currents caused due to the heating of the ground due to insolation. Convectional rainfall is prevalent in equatorial regions. In these, the warm air rises and expands then reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds.

Q. Q. In which of the following rainfall, the warm air rises up and expands then, reaches at a cooler layer and saturates, then condenses mainly in the form of cumulus or cumulonimbus clouds?

Q.  The air gets heated, becomes light, and rises up. As the air rises, it expands and temperature drops, and subsequently, cumulus clouds are formed. Heavy rainfall with lightning and thunder takes place which does not last long. Which of the following rainfall describes the above statements?

Q. Clouds are formed due to the condensation of the water vapour formed when warm air rises and cools down.

Q. In tropical rainforests, the heat carries moisture up to the atmosphere where it forms clouds which then condenses into rainfall in a process called Orographic rainfall.

Q. Choose the best option based on the four statements given below.

1. Saturation level is the point at which the relative humidity is 70%.

2. Orographic rainfall is more commonly seen in mountainous regions.

3. Cumulus clouds are formed at a height of 4,000 to 7,000 m.

4. Temperature does not affect the humidity of a place.
