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]
Earth is the only place in the universe known to harbor life, where it exists in myriad environments. [8] [9] The origin of life on Earth was at least 3.5 billion years ago, possibly as early as 3.8-4.1 billion years ago. [2] [3] [4] Since its emergence, life has persisted in several geological environments.
How the Earth Was Made is a documentary television series produced by Pioneer Productions for the History Channel. It began as a two-hour special exploring the geological history of Earth , airing on December 16, 2007.
The Parker Solar Probe is also the fastest thing ever made on Earth. Nasa said the mission operations team at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel , Maryland , received the ...
The history of life on Earth traces the processes by which living and extinct organisms evolved, from the earliest emergence of life to the present day. Earth formed about 4.5 billion years ago (abbreviated as Ga, for gigaannum) and evidence suggests that life emerged prior to 3.7 Ga. [1] [2] [3] The similarities among all known present-day species indicate that they have diverged through the ...
The following are amongst the oldest buildings in the world that have maintained the requirements to be such. Occupation sites with older human made structures, such as those in Göbekli Tepe do exist, but the structures are monuments and do not meet the definition of building (which can be seen above). Many of the buildings within the list ...
Before photosynthesis evolved, Earth's atmosphere had no free diatomic elemental oxygen (O 2). [2] Small quantities of oxygen were released by geological [ 3 ] and biological processes, but did not build up in the reducing atmosphere due to reactions with then-abundant reducing gases such as atmospheric methane and hydrogen sulfide and surface ...
