With temperature, rainfall is perhaps the most important factor in defining climate. Excess rainfall can cause flooding and enormous property and crop damage. Still, a deficiency of rainfall can cause drought and crop failure. Rainfall is also the major source of energy that drives the circulation of the atmosphere.
Why rainfall is so important?
Rain and snow are key elements in the Earth’s water cycle, which is vital to all life on Earth. Rainfall is the main way that the water in the skies comes down to Earth, where it fills our lakes and rivers, recharges the underground aquifers, and provides drinks to plants and animals.
What is rainfall and why is it important?
Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides suitable conditions for many types of ecosystems, as well as water for hydroelectric power plants and crop irrigation.
Climate change can affect the intensity and frequency of precipitation. Warmer oceans increase the amount of water that evaporates into the air. When more moisture-laden air moves over land or converges into a storm system, it can produce more intense precipitation—for example, heavier rain and snow storms.
Why is water so important when it comes to the climate?
As temperatures rise, people and animals need more water to maintain their health and thrive. Many important economic activities, like producing energy at power plants, raising livestock, and growing food crops, also require water.
Why is rainwater important to us?
For the survival of plants and animals, rainfall is very important. It helps in bringing fresh water to the surface of the earth. … If it is less than water scarcity and drought are likely to occur. On the other hand, if it is more, then the floods can also take place.
How is rain water useful to us?
The rain provide us fresh water for drinking or for many other purposes. 1> Rain water keep cooling the environment. 2> Rain water very useful for agriculture. 3> Rain water very useful for groundwater storage.
Why is rainfall important short answer?
Rainfall is very important for the survival of plants and animals. It brings fresh water to the earth’s surface. If rainfall is less, there is water scarcity which sometimes causes drought like situation. If there is excess rain, floods take place which makes the life of the affected people miserable.
Why is rain good for the environment?
What are the good effects of rain? 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 happens when there is too much rainfall?
Heavy rainfall can lead to numerous hazards, for example: flooding, including risk to human life, damage to buildings and infrastructure, and loss of crops and livestock. landslides, which can threaten human life, disrupt transport and communications, and cause damage to buildings and infrastructure.
How does climate change affect hydrology?
Generally, an increase in temperature enhances the moisture holding capacity of the atmosphere and thus, leads to an intensification of the hydrological cycle. Key changes in the hydrological system include alterations in the seasonal distribution, magnitude and duration of precipitation and evapotranspiration.
How does rainfall affect water systems?
Warmer air can hold more water vapour, one consequence of which is an increased frequency of heavy rainfall events. … The warmer air that causes increased evaporation makes the soil dry out. When rain does come, much of the water runs off the hard ground into rivers and streams, and the soil remains dry.
