Mantle plumes are in the mantle, BELOW the Earth's crust. The circulation of heat from the lower mantle to the upper mantle can cause "hot spots" in the overlying crust, heating the magma in the areas.
Inner core: 2450 km thick Outer core: 2300 km thick Lower mantle: 2500 km thick Upper Mantle: 400 km thick continental crust: 30-70 km thick Oceanic Crust: 6 km thick
crust, Lithosphere, Asthenosphere, lower mantle, outer core, inner core
The 3 main layers of earth (crust, mantle, core) are divided into crust, upper mantle, lower mantle, outer core, and inner core.
After the lithosphere is the asthenosphere, then comes the lower mantle. After that is the outer core, and then is the inner core.

Upper Mantle.
the lower boundary of the crust
Biosphere
Because it is near the earths crust were is our home
all of it it is the lower part of it
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
The lowest spots in the Earth's crust are found in the Mariana's Trench. It is located in the floor of the western North Pacific Ocean
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.

50 to 300 degrees f.
The upper mantle is in between the lower mantle and the earths crust Crust- the outer most solid shell of the earth. The Uppermost mantle and the earth's crust form the lithosphere.
