Which portion best illustrates the Lithosphere?
A Uppermost mantle bottom Oceanic Crust
B Continental Crust
C Asthenosphere (part of mantle)
D Mantle continues downward
I think it’s c well I honestly don’t know
Lithosphere: the rigid outer part of the earth, consisting of the crust and upper mantle
The portion that best illustrates the lithosphere is option B, the Continental Crust. To understand why, let's break down the options and explain what the lithosphere is.
The lithosphere is the rigid outer layer of the Earth, consisting of the crust and a portion of the uppermost mantle. It is divided into two types: the continental crust and the oceanic crust.
Option A mentions the uppermost mantle and the oceanic crust, but does not specifically mention the continental crust, which is a significant component of the lithosphere.
Option C refers to the asthenosphere, which is a part of the mantle and not part of the lithosphere. The asthenosphere is a weaker, more ductile layer below the lithosphere.
Option D mentions the mantle continues downward, which is true, as the mantle extends all the way down to the Earth's core. However, the lithosphere specifically refers to the uppermost layer of the Earth's solid surface, which includes the crust.
Therefore, option B, the Continental Crust, is the portion that best illustrates the lithosphere since it is one of the two major components of the lithosphere, along with the oceanic crust.
