How do springs originate at the top of the hills and how do they acquire such volume of water?

Question

One explanation that I found was rainfall but it is not apparent that rainfall could contribute to such volume of water.

Answer 1

There is so much water in the ground that it’s crazy. Springs are just where the land goes below the water table and it bubbles out.

The water comes from meteor strikes, volcanic eruptions, rainfall, glacial melt, etc. On top of all this geomorphological forces change the shape of the land and the water table over time, which moves where the rivers and streams are.
