Water Cycle Explained for Students

The diagram shows the four main stages of the water cycle: 1) evaporation of water from oceans and lakes into vapor, 2) condensation of vapor into clouds, 3) precipitation of water back to the Earth's surface as rain or snow, and 4) collection of precipitation in lakes and oceans where it evaporates again, completing the cycle. The cycle is a continuous process where water is recycled and redistributed around the planet.

Sample answer 1
The chart illustrates the circulation of water in nature.
Overall, it is clear that there are three primary stages in this process, beginning with water
evaporation and the formation of a cloud. The next step shows the water‘s journey after
falling to the ground, and the process ends with saltwater intrusion.
At the first step of the process, water evaporates into the air, as a result of the sun’s heat. It
is estimated that 80% of total water vapour is taken from the ocean. Following this, a cloud
is formed by the condensation of water vapour.
In the next stage, the heavy clouds cause rain or snow. Water from the precipitation partly
pours into the lakes or is absorbed into the ground. The surface runoff, which is made from
rainwater, creates the groundwater and then flows back to the ocean without reaching the
impervious layer. The final stage of the process is saltwater intrusion, where water from the
ocean moves to the freshwater aquifers.
Sample answer 2
The diagram below shows the water cycle, which is the continuous movement of water
on, above, and below the surface of the Earth.

The picture illustrates the process in which water moves from ocean to air and then to land
through a natural process called the water cycle.

Overall, the cycle has four main stages. Water evaporates, forms clouds, returns back on
earth’s surface, and eventually runs back into the oceans again.

During the first three stages, Surface water evaporates due to the heat from the sun.
Approximately 80% of this water vapor comes from the oceans, also known as saltwater. 
Next, this vapor is condensed in the sky and forms clouds, which may travel to different
locations. At the third stage, water in clouds falls down on Earth as rain or snow (the
phenomenon known as precipitation) and creates Lakes as well as snow caps on mountains.

Following precipitation, some of the water reaches the impervious layer of the ground, and
some run on the surface. Eventually, this water finds its way back into the ocean to complete
the cycle. However, just before entering the ocean, the surface runoff mixes with saltwater,
which has already moved into land, and pushes it back into the ocean.
