A. False. It is also made up of Gutenberg discontinuity,Mohorovicic Discontinuity,Hydrosphere & many othersPS: The crust is also called Lithosphere.
B. True. Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form
C. True.
D. True. Formed by crystallizing melted material (magma)
E. True.
Sorry for the long explanations. Hope it helps!! :)
Answer:
They´re a source of invaluable information. The study of these cosmic materials allows us to gain knowledge about the history of the solar system, about processes and primary conditions in the universe. We can learn the age and the composition of the planetary building blocks, the temperatures reached at the surface and interiors of asteroids, what kind of effect do materials experience due to impacts in the past.
Explanation:
Answer:
1.422
N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= 
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =
=1.422 N/m²
It's one of the following:
1) Social Science
2) Sociology
3) Anthropology
I'm leaning towards social science, but there are far too many variables in what constitutes a probable, correct response to this particular question.
