When the 2013 meteor entered into the Earth's atmosphere with an energy release equivalent to 100 or more kilotons of TNT, dozens of times more powerful than the atomic bomb dropped on Hiroshima, the meteor's shock wave produced damage as in a supersonic jet's flyby (directly underneath the meteor's path) and as a detonation wave, with the ...
A mesoscale convective complex has either an area of cloud top of 100,000 km 2 or greater with temperature less than or equal to −32 °C, or an area of cloud top of 50,000 km 2 with temperature less than or equal to −52 °C.
Also actiniform. Describing a collection of low-lying, radially structured clouds with distinct shapes (resembling leaves or wheels in satellite imagery), and typically organized in extensive mesoscale fields over marine environments. They are closely related to and sometimes considered a variant of stratocumulus clouds. actinometer A scientific instrument used to measure the heating power of ...
Shock stationed clay mineral from the Puchezh-Katunsky meteorite crater. Meteorite shock stage is a measure of the degree of fracturing of the matrix of a common chondrite meteorite. [1]
Shock waves in stellar environments, such as shocks inside a core collapse supernova explosion often become radiation mediated shocks. Such shocks are formed by photons colliding with the electrons of the matter, and the downstream of these shocks is dominated by radiation energy density rather than thermal energy of matter.
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
Although a meteor may seem to be a few thousand feet from the Earth, [25] meteors typically occur in the mesosphere at altitudes from 76 to 100 km (250,000 to 330,000 ft). [26] [27] The root word meteor comes from the Greek meteĊros, meaning "high in the air". [23] Millions of meteors occur in Earth's atmosphere daily.
When a meteor strikes a planet's surface, the energy released from the impact can melt rock and soil into a liquid. The liquid then cools and becomes an impact melt. [2] If the liquid cools and hardens quickly into a solid, impact glass forms before the atoms have time to arrange into a crystal lattice.
