Water

When we hear "water", images like rivers, rainfall, waterfalls come to our mind.

We use water to meet many of our daily needs.

This water undergoes a cycle before it meets our daily needs.

The cycle is known as the water cycle in which water circulates between the water bodies, air, and land in different forms.

Let us discuss the process of the water cycle.

In the water cycle, due to the Sun's heat, water evaporates to form the water vapors in the atmosphere.

Then these water vapors cool and form clouds in the atmosphere.

From clouds, they fall back to the ground as rain, snow or hail.

Again the process gets repeated when the rainwater evaporates from water bodies.

So the same water goes through the process of the water cycle on earth.

That means the water which existed a million years ago when the dinosaurs survived, still exists today.

Water is distributed in different water bodies.

We all know three-fourth of Earth is covered with water.

We can see this water in the form of freshwater and salty water.

The major resources of freshwater are the rivers, ponds, springs, and glaciers.

The major resources of saline water are seas and oceans. They contain a large number of dissolved salts.

The most famous one is sodium chloride or the salt that we eat.

Revision

The water cycle is the cycle in which water circulates between the water bodies, air, and land in different forms.

In the water cycle, water evaporates to form water vapours when it gets heated due to the Sun.

And then these water vapours when cooled form rain, snow or hail. Again the water evaporates and goes through a repeated cycle.

Water is distributed in the form of fresh water and saline water.

Fresh water resources are rivers, lakes, groundwater, and glaciers.

Salt water resources are seas and oceans. We get salt form these waters.
