Where Rain Comes From

Where Rain Comes From?

Clouds are made of water droplets. Within a cloud water droplets condense onto one another causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud they fall to Earth as rain.

How is rain formed?

Does rain come from the sea?

A good bit of the rain that falls over land comes from the oceans. Eventually some of that water makes its way back to the oceans beginning the cycle all over again. Earth’s water cycle is complicated. Sun-warmed water evaporates from the oceans and lakes.

Where does most rainwater come from?


Rain is droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves as well as oceans lakes and rivers into water vapour (gas) which disappears into the air. This vapour rises cools and changes into tiny water droplets which form clouds.

Why does rain happen?

Clouds are made up of tiny water droplets. When these droplets grow they eventually become too heavy to stay suspended in the sky and fall to the ground as rain. Some droplets fall through the cloud and coalesce into raindrops on their way down.

Is rain water clean water?

Most rain is perfectly safe to drink and may be even cleaner than the public water supply. Rainwater is only as clean as its container. Only rain that has fallen directly from the sky should be collected for drinking. … Boiling and filtering rainwater will make it even safer to drink.

How old is the water on Earth?

3.8 billion years ago

Why is rain not salt water?

In the beginning the primeval seas were probably only slightly salty. But over time as rain fell to the Earth and ran over the land breaking up rocks and transporting their minerals to the ocean the ocean has become saltier. Rain replenishes freshwater in rivers and streams so they don’t taste salty.

How do clouds form rain?

Precipitation forms in the clouds when water vapor condenses into bigger and bigger droplets of water. When the drops are heavy enough they fall to the Earth. If a cloud is colder like it would be at higher altitudes the water droplets may freeze to form ice. … Most rain actually begins as snow high in the clouds.

Where does the rain water fall pouring?

When it rains where does it go? Once on the land rainfall either seeps into the ground or becomes runoff which flows into rivers and lakes.

Why does rain make you sleepy?

Decreased oxygen content in the air

Oxygen can stimulate the brain and make us feel refreshed. When it rains there is more water vapor in the air it results in lower air pressure and a relative decrease in oxygen content. In such a situation brain begin to slack off and people will feel sleepy.

Is rainwater good for skin?

Who invented water?

Who discovered the water? It was the chemist Henry Cavendish (1731 – 1810) who discovered the composition of water when he experimented with hydrogen and oxygen and mixed these elements together to create an explosion (oxyhydrogen effect).

Why is the ocean blue?

The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green red or other hues as light bounces off of floating sediments and particles in the water.

Can you drink rainwater?

Can it rain without clouds?

Because rain forms when droplets of condensed moisture grow large enough to descend quickly into the air their absence can make it impossible for rain to occur. That means if there are no clouds overhead rain cannot happen as well.

How heavy is a cloud?

A typical cloud has a volume of around 1km3 and a density of around 1.003kg per m3 – about 0.4 per cent lower than that of the surrounding air which is why they float. So cranking through the maths that means that a typical cloud weighs around a million tonnes.

Why are clouds white?

Clouds are white because light from the Sun is white. … But in a cloud sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.

What if it rained every day for a year?

Another consequence of the persistent rain would be a severe lack of oxygen for us to breathe. Healthy soil contains oxygen. But with so much water in it that there would be much less room for oxygen. Water erosion would expose roots and make trees and plants unstable.

How deep is rainwater in the ground?

An inch of rain will wet the soil to a depth of 1 foot if there is no runoff and the soil is a sandy loam. If your soil trends to more sand it will penetrate further and it will be more easily absorbed but it won’t be retained as long.
