Question

Which of the following is not true of the Earth's mantle?

1) the mantle undergoes convection
2) the mantle is composed mainly of iron, oxygen, silicon, and magnesium
3) the mantle accounts for most of Earth's volume
4) the lithosphere is contained entirely within the Earth's mantle
5) the mantle is a source of heat and magma for much of Earth's volcanic activity

Answer 1

The statement that is not true of the Earth's mantle is that the lithosphere is contained entirely within the Earth's mantle.

Step-by-step explanation:

The statement that is not true of the Earth's mantle is the lithosphere is contained entirely within the Earth's mantle.The mantle is the layer below the crust and it is composed mainly of iron, oxygen, silicon, and magnesium. It accounts for most of the Earth's volume and is a source of heat and magma for much of Earth's volcanic activity.However, the lithosphere is not contained entirely within the mantle. The lithosphere is the rigid outer part of the Earth, which includes the crust and a small portion of the uppermost mantle.
