20 meter deep

CAMEL THORN common name for wild thorny suffrutescent plants of the Papilionaceae family.

40 meter deep

Nemo 33 is an indoor swimming pool facility in Brussels, Belgium. It held the record as the deepest indoor swimming pool in the world since its opening on May 1, 2004, until the completion in Mont grotto Terme, Padua, Italy on June 5, 2014.

The pool’s maximum depth is 34.5 metres (113 ft.). It contains 2,500,000 litres (550,000 imp gal; 660,000 US gal) of non-chlorinated, highly filtered spring water maintained at 30 °C (86 °F) by a solar heater and holds several simulated underwater caves at the 10 metres (33 ft.) depth level.

60 meter deep

The Derinkuyu underground city is an ancient multi-level underground city in the Derinkuyu district in Nevşehir Province, Turkey. Extending to a depth of approximately 60 m (200 feet), it is large enough to have sheltered as many as 20,000 people together with their livestock and food stores. It is the largest excavated underground city in Turkey and is one of several underground complexes found across Cappadocia.

105 meter deep

Arsenalna is a station on Kiev Metro’s Sviatoshynsko-Brovarska Line. The station was opened along with the first stage and is currently the deepest station in the world (105.5 metres). (The cancelled Porta Alpina station would have been 800 meters underground if completed.) This attributed to Kiev’s geography where the high bank of the Dnieper River rises above the rest of the city.

1370 meter deep

Yakutsk is the biggest city built on continuous permafrost, and most houses there are built on concrete piles.
Yakutsk is responsible for a fifth of the world’s production of diamonds, and is home to ALROSA and other mining companies. The city is also home to a significant food industry, to tanneries, to sawmills, and to factories for building materials.

1642 Meter deep

Lake Baikal is the largest freshwater lake by volume in the world, containing roughly 20% of the world’s unfrozen surface fresh water. With a maximum depth of 1,642 m (5,387 ft.), Baikal is the world’s deepest lake. It is considered among the world’s clearest lakes and is considered the world’s oldest lake at 25 million years. It is the seventh-largest lake in the world by surface area. With 23,615.39 km3 (5,700 cu mi) of fresh water, it contains more water than all the North American Great Lakes combined

4500 Meter deep

The TauTona Mine or Western Deep No.3 Shaft, is a gold mine in South Africa. At 3.9 kilometres (2.4 mi) deep it is currently home to the world’s deepest mining operations rivalled only by Mponeng gold mine with which it competes for #1 ranking.[

6700 Meter deep.

Fossilized stromatolites provide ancient records of life on Earth by these remains, some of which date from more than 3.5 billion years ago. Lichen stromatolites are a proposed mechanism of formation of some kinds of layered rock structure that are formed above water, where rock meets air, by repeated colonization of the rock by endolithic lichens.

12262 Meter deep

The Kola Superdeep Borehole is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth’s crust. Drilling began on 24 May 1970 using the Uralmash-4E, and later the Uralmash-15000 series drilling rig. A number of boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262-metre-long (40,230 ft.) in 1989 and still is the deepest artificial point on Earth.

70000 Meter deep.

The crust ranges from 5–70 km (~3–44 miles) in depth and is the outermost layer. The thin parts are the oceanic crust, which underlie the ocean basins (5–10 km) and are composed of dense (mafic) iron magnesium silicate igneous rocks, like basalt. The thicker crust is continental crust, which is less dense and composed of (felsic) sodium potassium aluminium silicate rocks, like granite. The rocks of the crust fall into two major categories – sial and sima (Suess, 1831–1914), which is 70000 meter deep from the first layer.

6381000 Meter deep.

The Earth consists of the crust (which are all standing on), the upper mantle (solid), the mantle (mostly solid), the outer core (molten iron-nickel), and the inner core (solid iron-nickel). The outer core is molten due to very high temperatures, but the increased pressure at the centre of the Earth means that the inner core remains solid. The distance to the centre of the Earth is 6,371 kilometres (3,958 mi), the crust is 35 kilometres (21 mi) thick, the mantle is 2855km (1774 mi) thick — and get this: the deepest we have ever drilled is the Kola Superdeep Borehole, which is just 12km deep. In truth, we have almost no direct knowledge of anything beneath the crust — all of our data is inferred from the seismic waves of earthquakes bouncing off the various layers, and from various bits of the Earth’s interior that bubble up to the surface, such as volcanic magma.
