Describe the core large sphere of metal that forms the center of the Earth.
the theory that pieces of the crust's outermost layer, called plates, move slowly (about 1.4 inches per
Plate tectonics
year)
Two types of plates oceanic and continental
, occur when oceanic plates move apart. Here, magma from the mantle rises to the earth's surface
Divergent plate boundaries
and forms new rock. This results in seafloor spreading.
Convergent plate boundaries form in areas where plates move toward each other and collide, creating mountains.

Igneous rock examples basalt, obsidian, granite
