4. Give a brief explanatory answer of the following (Alternative should be noted)
4.1 Explain why delta is formed at the mouth of a river.
Ans: In the lower course of the river the slope of the land decreases remarkably. This causes the river to become sluggish. The load carrying capacity of the river also reduces to a great extent near the sea. So, most of the load carried by river is ultimately deposited into the sea into which it flows. The deposition builds up a fan shaped alluvial-cone on it’s mouth and it is called delta.
or,Why does temperature decrease with increase of altitude in Troposphere?
Ans: In the troposphere, the temperature generally decreases with altitude. The reason is that the troposphere’s gases absorb very little of the incoming solar radiation. Instead, the ground absorbs this radiation and then heats the tropospheric air by conduction and convection.

Ans: Disposal of gaseous wastes are generally done through wet scrubber. Scrubber is a air-stream pollution control device which uses liquid spray to remove solid and liquid particulate matter and gaseous pollutants.
