Is rain a natural source of water?
There are a total of three natural sources of water.
They are categorized as: rain water, underground water and surface water.
The precipitation that falls to the Earth is a major part of the water cycle as it replenishes both surface and underground water sources..
Is rain water clean?
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 yearsThere is also geological evidence that helps constrain the time frame for liquid water existing on Earth. A sample of pillow basalt (a type of rock formed during an underwater eruption) was recovered from the Isua Greenstone Belt and provides evidence that water existed on Earth 3.8 billion years ago.
Does all rain come from the ocean?
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. … When the water droplets in the clouds get heavy enough, they fall back to the surface as rain, snow, or other forms of precipitation.
Where does all the water come from when it rains?
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.
What happens to the water that does not fall into oceans or other water sources when it rains?
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Ice and snow can sublimate directly into water vapor. … Most precipitation falls back into the oceans or onto land, where, due to gravity, the precipitation flows over the ground as surface runoff.
