What is precipitation?

( Chapter 5: Water, Class 7- Our Environment ( GEOGRAPHY), SOCIAL SCIENCE)


Precipitation refers to any form of water, liquid or solid, that falls from the sky and reaches the Earth's surface. 

Precipitation is a vital part of the Earth's water cycle and includes various forms:


Liquid water droplets fall from the sky when the atmospheric conditions are above freezing temperature. It is called rainfall.


Ice crystals that fall when temperatures are below freezing, forming snowflakes.


Tiny ice pellets form when raindrops freeze before reaching the ground. So, this type of precipitation is known as sleet.


Larger ice pellets form in severe thunderstorms when strong updrafts carry raindrops into freezing upper layers of the atmosphere.


Drizzle is light rain which is characterized by very small water droplets.

Freezing Rain: 

Rain falls while the surface temperatures are below freezing, creating a layer of ice on surfaces.

Precipitation plays a critical role in replenishing the Earth's freshwater resources, providing moisture for plant growth, filling rivers and lakes, and maintaining the overall balance of the planet's ecosystems. 

Precipitation is also an essential component of weather patterns and climate.
