Mantle and core
some features of the crust is basalt and granite.some features of mantle is lithosphere and asthenosphere. some features of the core are inner core and outer core.
They learn about the earth's interior by direct evidence from rocks and indirect evidence from seismic waves.
seismic wave-when earthquacks occur., pressure-result from a force pressing on an area., basalt-is a dark,fine grained rock., granite-is usually is a light color and has coarse grains., lithosphere-the uppermost mantle., asthenosphere-soft layer.
