yes that is where w get all of our rocks and dirt. I live in Georgia so we have red clay though!
the mantle and crust
Ultramafic minerals, iron, magnesium.
Tectonic plates are floating on the magma (semi-molten rocks) of the mantle layer. Therefore, they form the crust layer of the Earth.
The Earths mantle is filled with ferromagnesian rocks with minerals such as Olivine and Pyroxene.
Because the Upper Mantle has a molten layer that has MAGMA so thats why the rocks melt.

The outer layer of the earth is the crust. Earth has three layers. Beneath the crust is the mantle, which is made of semi-solid magma, solid rocks and minerals.

The mantle is the hot rock.
The Mantle--The layer directly below the crust which is delineated from the crust by the Mohorovicic Discontinuity, where seismic waves increase in velocity. The division between the mantle and the crust is a chemical one, the rocks and constituent minerals being higher in magnesium and lower in silicon and aluminum than crustal rocks. The mantle comprises 84% of Earth's volume.
The upper mantle.
Ultramafic minerals, iron, magnesium.
The lithosphere is the hard, brittle outer layer of the Earth, comprised of the crust and uppermost mantle.
The upper mantle.
The Earth's mantle is a rocky layer between the crust and the core, so it's made of of solid material, not liquid. It's comprised of minerals that contain mostly silicon, oxygen and magnesium. (From "The Cosmic Perspective - Sixth Edition").
