Earth’s Interior

Crust Outermost layer of solid rock that includes both dry land and ocean floor 5-70 kilometers thick Two Types Oceanic Crust - made of mostly basalt Continental Crust - made of mostly granite

Mantle Made of very hot, but solid rock About 3000 kilometers thick Moho - the boundary between the mantle and the crust Lithosphere - crust & upper mantle Asthenosphere - soft layer of mantle, like road tar Lower mantle - solid, hot rock

Outer Core Molten, liquid metal

Inner Core Dense ball of solid metal
