Asthenosphere: soft mantle which pieces of lithosphere move on.Solid rock move slowly (speed of fingernail growth)
Pressure, density and temperature increase as depth increase
-
Crust
continental:older, more complex,thick
Oceanic: denser, younger,thinner
Mantle
upper mantle//convection currents: hot magma rise to the top , cools and sinks and again, cause changes on earth surface // lower mantle

constructive plate boundary(divergent)
plates apart, new magma rise to fill the gap
