The day people started to make the deepest hole – level 1

The deepest hole made by people is in Russia. The name of the hole is the Kola Superdeep Borehole.

The work on the hole starts on 24 May 1970. Scientists make this hole. They want to go very deep. They want to study the Earth.

The hole is 23 centimeters wide. People reach the deepest point in 1989. It is 12,262 meters deep. Drilling then stops because the temperature is too high.

Difficult words: deepest (the most deep), reach (to get to some place).

What was the purpose of creating the Kola Superdeep Borehole? How deep did people manage to drill and why did they have to stop?
