well because of the sufuce of the earth and it is closer to cold air i would say on the surface
The Earth's core is much warmer than the surface due to the heat from its formation and radioactive decay of elements. As you go deeper into the Earth, this heat is trapped, causing the temperature to increase. This creates a geothermal gradient, where temperatures rise steadily as you go deeper underground.
The underground liquid rock is called magma when it is beneath the Earth's surface. When magma reaches the surface, it is then referred to as lava.
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
The two main types of mining are surface mining and underground mining. Surface mining involves extracting minerals or resources from the Earth's surface, while underground mining involves extracting resources from beneath the Earth's surface. Surface mining is generally more cost-effective and less dangerous, but it can have a larger environmental impact compared to underground mining. Underground mining, on the other hand, can be more expensive and pose greater safety risks, but it is less disruptive to the environment.
Magma is the name given to molten underground rock. It can be found beneath the Earth's surface in the mantle and can eventually rise to the surface through volcanic activity.
I think it is because of the good insulation of earth surface to the under ground water
Almost always warmer at the surface.
upwhelling
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.
A rock at the surface will cool faster than a rock underground.
simple- underground and surface water ,both are the water only
The Earth's core is much warmer than the surface due to the heat from its formation and radioactive decay of elements. As you go deeper into the Earth, this heat is trapped, causing the temperature to increase. This creates a geothermal gradient, where temperatures rise steadily as you go deeper underground.
Because it is safer for them. It is also cooler/warmer, depending.
Underground is an adverb, as in beneath the surface of the ground. It is an adjective, as in an underground car park
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.
