Answer 2

The lower mantle exhibits hot spot volcanism.

Explanation:

Between the crust and the outer core, the Earth's mantle is a layer of silicate rock. It has a mass of 4.01 1024 kg, accounting for 67 percent of Earth's mass. It is 2,900 kilo meters (1,800 miles) thick and accounts for roughly 84 percent of the Earth's bulk. It is mostly solid, but over geologic time periods it acts like a viscous fluid, with a viscosity that has been compared to caramel. Oceanic crust is formed by partial melting of the mantle at mid-ocean ridges, while continental crust is formed by partial melting of the mantle in subduction zones.
