Deepest drillings. The Kola Superdeep Borehole on the Kola peninsula of Russia reached 12,262 metres (40,230 ft) and is the deepest penetration of the Earth’s solid surface. The German Continental Deep Drilling Program at 9.1 kilometres (5.7 mi) has shown the earth crust to be mostly porous.
What is the largest hole on Earth?
There are several contenders for the largest man-made hole, depending on how you measure it, but our money’s on a mine. It depends how you measure it. The Chuquicamata opencast copper mine in Chile has the greatest volume of excavated earth (roughly 9 billion cubic metres) but it’s a ditch rather than a hole.
What’s at the bottom of Berkeley Pit?
The Berkeley Pit is a former open pit copper mine located in Butte, Montana, United States. It is one mile long by half a mile wide with an approximate depth of 1,780 feet (540 m). The pit’s water contains so much metal that at one point one of its owners, Montana Resources, mined copper directly from the water.

How thick is Earth’s crust?
The crust of the Earth is of two distinctive types: Oceanic: 5 km (3 mi) to 10 km (6 mi) thick and composed primarily of denser, more mafic rocks, such as basalt, diabase, and gabbro. Continental: 30 km (20 mi) to 50 km (30 mi) thick and mostly composed of less dense, more felsic rocks, such as granite.
Is it possible to drill to the center of the Earth?
Humans have drilled over 12 kilometers (7.67 miles) in the Sakhalin-I. In terms of depth below the surface, the Kola Superdeep Borehole SG-3 retains the world record at 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth.
Why is the Earth’s interior so hot?
The flow of heat from Earth’s interior to the surface is estimated at terawatts (TW) and comes from two main sources in roughly equal amounts: the radiogenic heat produced by the radioactive decay of isotopes in the mantle and crust, and the primordial heat left over from the formation of the Earth.
What is a blue hole in the ocean?
The deepest blue hole in the world at 300.89 meters (987 feet) deep is in the South China Sea and is named the Dragon Hole, or Longdong. The second deepest blue hole in the world with underwater entrance at 202 metres (663 ft) is Dean’s Blue Hole, located in a bay west of Clarence Town on Long Island, Bahamas.

Is there still Mining in Butte Montana?
Butte is the county seat of Silver Bow County, Montana, United States. Despite the dominance of the Anaconda Copper Mining Company, Butte was never a company town. Other major events in the city’s history include the 1917 Speculator Mine disaster, the largest hard rock mining disaster in world history.
What is mined in Butte?
Copper ore mined from the Butte mining district in 1910 alone totaled 284,000,000 pounds (129,000,000 kg), making it the largest producer of copper in North America and second only to South Africa in world production of metals. The amount of ore produced in the city earned it the nickname “The Richest Hill on Earth.”

How thick is the core of the earth?
The outer core of the Earth is a liquid layer about 2,260 kilometers thick. It is made of iron and nickel. This is above the Earth’s solid inner core and below the mantle. Its outer boundary is 2,890 km (1,800 mi) beneath the Earth’s surface.
How much depth is the earth?
Earth’s mantle extends to a depth of 2,890 km, making it the thickest layer of Earth.
What is the pressure at the center of the Earth?
Pressure and gravity. The pressure in the Earth’s inner core is slightly higher than it is at the boundary between the outer and inner cores: it ranges from about 330 to 360 gigapascals (3,300,000 to 3,600,000 atm).
