earth's interior
Beneath the crust
The earth's interior is everything beneath the surface—the layers of rock, molten material, and metal extending to the planet's core.
Geologists divide it into crust, mantle, outer core, and inner core, each with distinct composition and behavior.
The phrase appears in discussions of earthquakes, volcanoes, and planetary science: Scientists study the earth's interior through seismic waves.
