well because of the sufuce of the earth and it is closer to cold air i would say on the surface
When warmer air rises so when a localized surface is warmer than its surroundings, the air above that surface is warmer and will also rise. This also makes clouds.
Advantages of Underground Mining are: * It allows minerals to be extracted from deep underground * It doesn't create a mess like open cut or surface mining * Does not affect the physical environment as much as surface mining

I think it is because of the good insulation of earth surface to the under ground water
Almost always warmer at the surface.

Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
what is the upper surface of ground water
The earth surface is warmer in the northern hemisphere when it issummer there because of the angle of the sun. For the same reason,the Earth's surface is warmer in the southern hemisphere when it isSummer there.
When warmer air rises so when a localized surface is warmer than its surroundings, the air above that surface is warmer and will also rise. This also makes clouds.
simple- underground and surface water ,both are the water only
A rock at the surface will cool faster than a rock underground.
Underground is an adverb, as in beneath the surface of the ground. It is an adjective, as in an underground car park
Because it is safer for them. It is also cooler/warmer, depending.
The astronomers suppose that the water is frozen underground there. Long time ago Mars was warmer and water flows out. That's why the Curiosity car found peeblestones on the surface of Mars.
