Answer:
Option (2)
Explanation:
The earth's interior is divided into 3 parts which includes the crust, core and the mantle. The core of the earth represents the extreme interior part of the earth which is covered by the mantle. The density of the core is the highest and is approximately 13 g/cm³, Whereas, the density of the mantle (including both the upper and lower mantle) is relatively less and is about 4.5 g/cm³ on an average.
The asthenosphere is the layer in which the rocks are solid but they tends to flow during deformation. This layer is present in the apex portion of the upper mantle and it has a density of nearly 3.3g/cm³.
The continental and the oceanic crust represents the outermost portion of the earth. The rocks of oceanic crust are denser than the rocks of continental crust. The density of the oceanic crust is nearly 3 g/cm³ and continental crust is 2.7g/cm³.
Thus, the continental crust is the less dense, compared to the other layers of the earth.
Hence, the correct answer is option (2).
1. -18-6x=6+18x
-18-6=18x+6x
24x=-24
x=-1
2.8x-6-8=4+2x
8x-2x=18
6x=18
x=3
