Question

What happens to rainwater that falls on land?

Answer 1

Several things can happen

Explanation:

Part of it will evaporate, part will soak into the soil, and part will flow off to lower regions, where it may gather into rivers and finally into the sea. Part of the soaked up water will also eventually follow one of the other routes.
All of these possibilities, and the ratio between them, are subject to the local conditions, such as temperature, type of soil, height gradient, and more.
