where two of earths tectonic plates will moving apart
Ridge push
process connected to convection currents in the earths mantle , occurs when the weight of a elevated ridge pushes an oceanic plate towards a subsection
Magma
molten rock below the earths surface
Lava
Magma flowing onto the earths surface
Shearing
Stress that causes a material to twist
Seafloor spreading
Theory that the oceanic crust was created at the ocean ridges
Transform boundary
Place where two tectonic plates end up sliding horizontally away from each other
Compression
Stress that decreases the volume of a material
Asthenosphere
Highest layer on the earths mantle, but still lower than the lithosphere
Theory of continental drift
Wegeners theory that earths continent were once one big super continent called Pangea
