The pressure created by the considerable weight of the 1 mile of crust creates heat. Even small movements create a huge amount of heat due to friction as particles "scrape" past each other with such pressure.
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.
Pressure 1 mile below sea level is approximately 1,525 pounds per square inch (psi). This is due to the weight of the water column above exerting pressure on the depth below.
The Rift Valley, specifically the East African Rift system, is a 4000 mile crack in Earth's surface located in Africa. It is bordered by a number of high mountains, including Mount Kilimanjaro and the Ethiopian Highlands.
The soil temperatre increases as depth increases due to the heat created by the compression of the surrounding earth. The rate of change of temperature with depth is referred to as the geothermal gradient. The geothermal gradient varies depending on location, so there is no uniform answer. On average, the geothermal gradient is approximately 75 degrees F per mile. In volcanically active areas, the gradient can be as high as 150 degrees F per mile. In ocean trenches, the gradient may be as low as 15 degrees F per mile. Decay of naturally occurring radioactive elements may also cause localized increases in temperature in some locations.
Clouds vary in height above the Earth's surface from zero (called Fog) to "Noctilucent" clouds, about 50 miles above the surface. Common Cumulus clouds have their bottoms very roughly a mile above the surface. If you know the "dew point" from a weather forecast and there are clouds, you can usually estimate their height by multiplying one third of the difference between the surface temperature and the dew point by 1000 feet, so, for example, if the temperature is 72 degrees (F) and the dewpoint is 60 degrees, the clouds start to form at an altitude of (72-60)/3x1000 feet, or 4,000 feet. If there is a second layer of clouds above that, they are presumably ice clouds and their altitude is probably about (72-32)/3x1000 feet, or 13,000 feet.

The temperature of the deep seas is -1°c to 4°c. It's near freezing. Saltwater freezes at -1.8°c.
52 C°
one mile below the sea
a nautical mile is a minute (1/60th) of one degree of the earths surface so it corresponds to maps
High and low pressure systems. 1 mile south could be a low pressure system which would have a different temperature than a mile north with a high pressure system. Thats just one variable though.
Pressure 1 mile below sea level is approximately 1,525 pounds per square inch (psi). This is due to the weight of the water column above exerting pressure on the depth below.
According to the USGS, the water table in Houston ranges between 10 and 30 feet below the surface. (See link below). An exception is in Katy, where it is more than 75 feet deep. From personal experience, the water table is about 14 feet below my property--about 1/4 mile from Oyster Creek in Sugar Land.
The surface area is 290,000 square miles
Surface mining occurs close to the surface (less than a mile deep), while underground mining is underground.
I think it is the same....
The real answer is zero, since square feet defines a surface and mile defines a distance. Assuming you meant square mile: 5,300,000 ft^2
