Which is the best description of the process in the diagram?
F. When two continental plates slowly push into one another, they often fold upwards, creating mountain chains.
G. As plates move apart, magma rises up through cracks in the ocean floor, creating a ridge of mountains.
H. As semi-solid rock is heated it expands and begins to rise, then gravity pulls cooler denser rock creating a circular motion. The circular motion pushes the plates above.
J. Plate movements can cause a break in the Earth’s crust, known as a fault. As plates move, they create tremendous stress at plate boundaries sending vibrations known as seismic waves.
