#interiorofearth

□ DIRECT SOURCES

◇ Deep earth mining and drilling reveal the nature of rocks deep down the surface.

◇ But as mining and drilling are not practically possible beyond a certain depth, they don’t reveal much information about the earth’s interior.

◇ Mponeng gold mine (deepest mine in the world) and TauTona gold mine (second deepest mine in the world) in South Africa are deepest mines reaching to a depth of only 3.9 km.

◇ And the deepest drilling is only about 12 km deep hole bored by the Soviet Union in the 1970s over the Kola Peninsula.

◇ Volcanic eruption forms another source of obtaining direct information.
