![OE gravitational potential energy
Which statement is not true of the Earth's mantle?
OA The mantle undergoes convection.
OB The mantle is composed mainly of iron, oxygen, silicon, and magnesium
C. The mantle accounts for most of Earth's volume.
OD The lithosphere is contained entirely within the Earth's mantle.
OE The mantle is a source of heat and magma for much of Earth's volcanic activity
9.
In the graph (Figure 1), why does the line for seismic S-waves not appear in the outer core?
OAS-waves cannot travel through the outer core because it is solid.
B. S-waves cannot travel through the outer core because it is liquid.
C. S-waves disappear after being reflected at the core-mantle boundary
D. S-waves cannot travel that far into the Earth.
OESwaves are transformed into P-waves in the outer core by the high concentrations of iron and nickel there
