Question

How does the failure of rainfall affect people on the earth?

Answer 1

Hint: Rain is the precipitation in liquid form that descends to the earth. When trees are chopped on the slopes, rainwater pours down the bare mountains, and low-lying areas flood. Most of the water used is obtained by rainfall.

Complete answer:
Water is the most essential thing for plants, animals, and humans for survival. Usually, we get water from rivers, lakes, ponds, groundwater, etc. This water is used by farmers in farming.
And whenever the water level drops in rivers, lakes, ponds, groundwater, etc it is regained by rainfall and rainfall also helps in farming.
So, if there is a failure in rainfall there can be many consequences. These are:
Drought (drying up of soil)
Fall in the level of water in rivers, lakes, ponds, groundwater, etc. Drying of ponds and canals.
Fall in the groundwater level
Drought is a natural cause that is caused when there is very little or no rainfall. This affects the farmers and plants of the area very badly.
In cities and rural areas, people get water from nearby rivers, lakes, and ponds. If the water level decreases then there will be scarcity of water which will affect human life.
In some rural areas where seasonal rainfall is less, people get water from groundwater, so a fall in the level of groundwater will affect them.

Note:
Deforestation and global warming affect seasonal rainfall. In the interior, there are more seasonal contradictions than in the coastal districts. The rainfall decreases gradually from east to west in the northern plains.
