Which statement explains the relationship between the density of a material and its movement in Earth’s interior?

Question

Cooler materials move from Earth’s mantle to the lithosphere.
Cooler materials are highly dense, causing them to sink to the outer core.
Warmer materials sink to the mantle because their density slowly decreases.
Warmer materials have a high density, causing them to rise to Earth’s surface.

Answer 1

The statement that best explains the relationship between the density of a material and its movement in Earth’s interior is:

Cooler materials are highly dense, causing them to sink to the outer core.

This reflects the general principle that denser materials tend to sink, while less dense materials rise. In Earth's interior, cooler materials tend to be denser and thus can sink, while warmer materials are less dense and can rise. However, the chosen statement specifically highlights the sinking of dense, cooler materials.
