Answer:
A galaxy is a collection of stars and interstellar material held together by gravity. The galaxy our Sun lives in is called the Milky Way.
The name `Milky Way' comes from the band of light that is seen overhead on very dark nights.
A thick layer of interstellar dust hides much of the Galaxy from observation by optical telescopes, and astronomers can determine its large-scale structure only with the aid of radio and infrared telescopes, which can detect the forms of radiation that penetrate the hidden matter.
Answer:
Anatolian Plate
Explanation:
Aegean plate is a small tectonic plate located in the mediterranean sea to north is the eurasian plate which is the divergent boundary responsible for formation.
metamorphic rock are the rock which are formed when igneous rock and sedimentary rock change from one form to another form due to more heat and pressure. long time exposure of heat and pressure on the sedimentary rock and igneous rock changes them from one form to another form and metamorphic rocks get form
b. a low-lying region where Precambrian rocks are covered by Phanerozoic sedimentary strata
c. a region of compressed rock located behind a volcanic arc at a convergent continental margin
d. synonymous with craton
Answer:
The correct answer is D. Synonymous with craton
Explanation:
Craton is referred to as a large immobile block of earth crust composed of ancient crystalline basement rock and have deep lithosphere roots that extends deeply into the earth's mantle.
Cratons are often seen as shields because the basement rock crops out at the surface, and in platforms, the basement is overlaid by sedimentary rock.
Geographically, a shield and a surrounding platform together are synonymous with craton.
Answer:
True.
Explanation:
Answer:
Power per unit area released by the Sun is 73,488,384 Watt per meter square.
Explanation:
The Sun has an average surface temperature of approximately,T= 6000 K
The power per unit area released by the surface of the Sun be P'
Stefan-Boltzmann Law is given as:
where
Stefan-Boltzmann constant
T = Absolute temperature of the body
Power per unit area released by the Sun:
