Question

The most abundant element in earth's crust is:
A) Hydrogen
B) Oxygen
C) Nitrogen
D) Silicon

Answer 1

Hint:First we should be aware of the element which is most of the earth’s crust. Now the crust consists of various elements but then it is compared in the weight then the most share is of the element of oxygen. It consists of nearly half of the crust at an astonishing \[46\% \] according to weight.

Complete answer:Here in the given question statement the question is regarding the nature of the earth’s crust and the constituents that form it up. We have to categorize them or compare them in the terms of different elements.

The crust can be defined as the outermost solid shell of a celestial entity like a rocky planet, dwarf planet, or natural satellite. Although it is mostly used in the case of the planet and their undertaken study. For its differentiation from the other parts we can say that it is generally distinguished from the underlying mantle by the chemical makeup. Though for the case of the icy satellites, we can say that it may be distinguished moreover based on its phase which is mostly solid crust vs. liquid mantle.

-Now talking about the earth's crust we get that the most abundant element in the earth's crust is oxygen with a Percent by weight in the region of \[46\% \] which is followed by the next slot of aluminium with nearly $8\% $ by weight.

Therefore the correct answer is (B).

Note:Earth's crust is a thin shell on the outside of Earth, accounting for less than \[1\% \] of Earth's volume. It is the top component of the lithosphere, a division of Earth's layers that includes the crust and the upper part of the mantle. The lithosphere is broken into tectonic plates whose motion allows heat to escape from the interior of the Earth into space.
