The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
Boring is drilling a hole, tunnel, or well in the Earth. It is used for various applications in geology, agriculture, hydrology, civil engineering, and mineral exploration. Today, most Earth drilling serves one of the following purposes: return samples of the soil and/or rock through which the drill passes; access rocks from which material can ...
Google Earth is a web and computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles.
In the process, the gas significantly cooled down through contact with the shaft's walls. [7] [8] Most of the energy contained in the propellant (5 to 100 thousand hp) was spent on the actual digging, while the device lowered itself deeper into the well under its own weight. Tsiferov's device was capable of drilling the well tens of metres deep ...
The original calculations assumed that the Earth has the same density throughout - and the gravitational force changes as you approach the center, much like the weight of a spring that bounces up ...
Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large sample ...
Google Earth is a free program for Linux Macintosh or Windows which displays satellite photos, road maps, and other forms of geospatial information. If you can find a location, landmark, landform, stationary object, etc., on a satellite photo or road map, you can easily get its coordinates from Google Earth.
Project Mohole was an attempt in the early 1960s to drill through the Earth's crust to obtain samples of the Mohorovičić discontinuity, or Moho, the boundary between the Earth's crust and mantle. [2] The project was intended to provide an earth science complement to the high-profile Space Race.
