Question

What are the advantages and disadvantages of rainfall?

Answer 1

Answer:

Plant Life

Simply put, vegetation needs water to survive. Rain may inconvenience some people, but it is the lifeblood of necessary plants. Extended lack of rain has devastating effects, as evidenced by the dust bowl during the Great Depression, a seven year drought from 1931 to 1938 occurring over the Great Plains region of the United States. Another area of the world more recently affected is Africa, when the 1984-1985 Horn of Africa drought killed over 750,000 people because of famine.

Water Quality

Rainwater is better than artificial methods of irrigation because it doesn't have any added chemicals that the latter often have, such as chlorine. There is one caveat, however; when a polluted environment leads to acid rain, which harms human health and the environment, it limits the benefits of rainwater.

Mudslides

In the event of excessive rain following a dry period, mudslides can occur, with devastating effects. Not only do they erode valuable soil, they also can destroy homes and can be life-threatening. Usually, they occur on hills, and even if there aren't homes on the hillside, there is the danger of potentially fatal carnage to roads, businesses and houses at the bottom of the hill.

Flooding

Flooding destroys homes, businesses, and, in worst case scenarios, lives. Sometimes the flooding is cumulative, as when its source is several days of steady rain. However, flash floods are perhaps even more dangerous because they can sneak up on people who are either unprepared for them or who have underestimated their danger. There is also an negative economic effect, as cities and towns are forced to rebuild.

Answer 2

here is your answer Rainwater is usually free from harmful chemicals, which makes it ideal for irrigation purposes. Another important advantage is that it reduces demand for potable water. It is important especially in areas with low water levels.

These are some of the significant advantages of harvesting rainwater
Rainwater fills reservoirs that supply drinking water, provide a habitat for fish to live, and nourishes the soil with water necessary for vegetation. Rain water, however, can also have a negative effect on the Earth when it causes erosion or when it has a high pH.

What are the Disadvantages of the Monsoon Season? Monsoons have the potential to be extremely violent weather systems. Drought-stricken land can be suddenly drenched with several inches of rain. ... Arroyos and canyons are prone to flooding as runoff from higher areas rush to carry excess rainfall through to lower areas.
disadvantages of acid rain. Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct. ...






















The buildings can be found with sulfuric acid. soil can be affected and can lead to deaths of good microbes.

The Importance of Rain. Rain is an important part of the water cycle. The water cycle is the process by which water on the Earth's surface heats up and evaporates, or changes to water vapor, condenses in the clouds, and returns to the land as a form of precipitation.
