How have geologists learned about Earth’s Interior?

Rock Samples: drilling up to 12 km into Earth; tectonic faulting & uplift has revealed rocks from more than 100 km depth.

Seismic Waves: because rock layers have different densities, seismic waves move at different speeds through the rock layers. Geophysicists use this seismic wave data to construct a “picture” of the earth’s deep internal layers (e.g., crust, mantle, core)

Crust (outermost Earth layer)Crust: solid layer of rock. Two types:

•continental crust: forms the continent, granite in composition

•oceanic crust: forms the ocean floor, basalt in composition

Mantle (thick middle layer)Mantle: hot rock nearly 3000 km thick

Lithosphere: rigid, solid rock consisting of the crust and hot uppermost mantle; 100 km thick

Asthenosphere: softer, hot, clay-like rock that can bend.

Lower Mantle: solid rock

CoreCore: metal iron & nickel composition; liquid outer core and solid inner core; 3,486 km thick.

Outer core: the movement of the liquid outer core generates the Earth’s magnetic field.

Inner core: is solid because extreme pressure prevents the Fe, Ni atoms from spreading apart and becoming a liquid.
