Question

Which of the following is not true concerning the layers of the Earth?

a.
The core is mostly composed of metals.
b.
The mantle has both solid and liquid regions.
c.
The layers of Earth are uniform in thickness.
d.
The lithosphere includes both the crust and upper, solid mantle.

Answer 1

(C.) The layers of the Earth are uniform in thickness

This is untrue. The mantle is far large than the crust and there are other large size differences.

Answer 2

C. The layers of Earth are uniform in thickness.

Step-by-step explanation:

The earth is made up of three layers, the crust, the mantle and the core. Each layer has different characteristics and temperatures, becoming warmer as it approaches the core.

The Earth is formed by three layers that are not uniform in thickness, composition, or characteristic. These layers are:

• Earth's crust: Most superficial layer, relatively thin structure and very rocky.
• Mantle: Located below the crust, it has solid properties.
• Core: Earth's warmest inner layer. It has two parts:

1. Outer core: formed by nickel and liquid iron.
2. Inner core: Also formed of nickel, but with solid iron.
