Seafloor Spreading.!

Seafloor spreading power point.

Seafloor spreading Worksheet. :)

A piece of evidence is there is newer rocks in the middle and older rocks by the to coast line because as the magma comes up and it hardens, making new seafloor. So as its making new seafloor rocks its pushing the old ones out, and eventually then it starts going under the continents into the subduction zone and melts. Then the whole cycle starts again.

Plate Tectonics!!

Plate Tectonics theory The lithosphere is broken into several large pieces called plates. These plates are holding the continents and the oceans, which slowly move around the planets. It explains how volcano's erupt.
