Why is the water in some wells much warmer than in others?
In wells where the water is warm, the streams flowing into them are near the surface of the earth, and are heated by the sun; but in the wells of cold water, the streams are much deeper in the earth.
When these streams flow out at the surface of the earth, what are they called?
They are called springs.
Where are springs found?
They are mostly found on hill-sides, or in valleys; but they are sometimes found on the top of the hills.
Why is the water in some springs warmer than in others?
In springs where the water is warm, the streams flowing into them are so near the surface of the earth as to be warmed by the sun, while in springs where the water is colder, the streams are much deeper in the earth.
What becomes of the water in the springs?
It runs away down the valleys, forming brooks and creeks.
