3. The rock that makes up the lower mantle is more solid than the upper mantle. This is because the pressure inside the Earth.
O remains constant with depth
O decreases with depth
O increases with depth
O fluctuates with depth

Answer 1

The rock in the lower mantle is more solid than in the upper mantle due to increased pressure inside the Earth.

Step-by-step explanation:

The rock that makes up the lower mantle is more solid than the upper mantle due to the pressure inside the Earth. As we descend deeper into the Earth, the pressure increases significantly. This increased pressure compresses the rock particles in the lower mantle, making it more dense and solid. On the other hand, the pressure in the upper mantle is comparatively lower, allowing the rock to be less solid and more prone to flowing and deformations.
