Question

what is the eath hole?​

Answer 1

Answer:

Known as the Kola Superdeep Borehole, the deepest hole ever dug reaches approximately 7.5 miles below the Earth's surface (or 12,262 kilometers), a depth that took about 20 years to reach. The hole was intended to go “as deep as possible,” which researches expected to be around 9 miles (that's ~14,500 meters).

Answer 2

Answer:

This is the Kola Superdeep Borehole, the deepest manmade hole on Earth and deepest artificial point on Earth. The Soviets' superdeep borehole isn't alone. During the Cold War, there was a race by the superpowers to drill as deep as possible into the Earth's crust – and even to reach the mantle of the planet itself
