My report of a diagram about water cycle

My essay:

The flow chart illustrates the water cycle, which water goes through from ocean to air and then to land during the natural process.

It is clear from the chart that there are three principal steps which are registered on the process. Water from ocean evaporates, rains, and finally comes back into the oceans again.

Firstly, about 80% of total water vapour in air comes from the oceans on the evaporation stage. The sunlight causes water to evaporate, and water vapour condense to form clouds. Next steps, water in the clouds falls like a rain or snow.

At the last stage in the process, rainwater may take several ways. A number of it could fall into the lakes or comes back to the oceans as surface runoff. Moreover, rainwater undergoes through the ground, going to the impervious layer stage. Salt water intrusion is just a place that groundwater comes through to the oceans to complete the process.
