There are about 60,000 meters of rocky crust and magma that separate the Earth's surface from its core, but the deepest places that humans have reached on the planet's surface are much less than that distance, and some of them we do not have accurate information about, as we know about planets and stars close to Earth.

The American Brainberries website sheds light on the deepest places on Earth, from wells and mines, through caves and valleys, to sea trenches.

1. Woodingden Water Well: UK - 392 metres

Woodingden is located east of Brighton, in the far south of England, and is known for having the deepest well in the world.

The well was dug by hand between 1858 and 1862 by life sentences in the local prison, many of whom died while digging.

2. Vertigo Cave: Slovenia - 603 meters

Discovered by a group of Italian and Slovenian cave explorers in 1996, this cave contains the deepest karst well in the world, with a depth of 603 meters.

3. Bingham Valley Mine: United States - 970 meters

This mine is the largest man-made hole on the Earth's surface.

After more than a century of copper mining operations at the site, a large hole was formed with a depth of 970 meters, and this mine could accommodate the Burj Khalifa, which is 828 meters above sea level.

4- Lake Baikal: Russia - 1642 meters

Baikal is the deepest lake on the planet, with a depth of about 1642 meters.

5. Krubera Cave: Georgia - 2,250 meters

Krubera Cave is the deepest cave in the world, and is the only known cave so far, with a depth of more than two thousand meters.

6. Tautuna Mines: South Africa - 4500m

The world's deepest mines are located in South Africa, with a depth of more than 4,500 metres.

You can imagine the harsh conditions that miners have to endure there to extract the gold, as the temperature is 60 degrees Celsius.

7. Cangpu Grand Canyon: China - 6,000 meters

Located in Tibet, the Tsangpo Valley has a maximum depth of more than 6,000 meters, making it the deepest valley in the world.

8. Milwaukee Deep: USA - 8,740 meters

The Milwaukee Deep is the deepest point on the island of Puerto Rico and the entire Atlantic Ocean.

According to many geologists, a volcanic eruption may occur from this spot soon and cause a huge tsunami that kills many people.

9. Mariana Trench - 10,994 meters

The Mariana Trench is located in the deepest oceanic seas on Earth, specifically the western Pacific Ocean to the east of the Northern Mariana Islands.

The Challenger Deep is the deepest point in the Mariana Trench, with a depth - according to 2011 data - about 10,994 meters below sea level.

This trench is one of the least places on Earth for which accurate scientific data are not available.
