Dynamic Earth

1. Convergent Boundary-A plate collides with or dives under another.

 2. Divergent Boundary - Magma rises and pushes plates apart.
 * One Example is when India dived under Asia and is now raising the Himalaya Mountains.
 * Another Example Occurs where a plate of ocean dives, in a process called subduction were one plate dives under another forming deep trenches like Marina Trench.
 * The diving plate melts and is often spewed out in volcanic eruptions such as those that formed some of the mountains in the Andes of South America.

 3. Transform Boundary - Two plate grind against each other.
 * In the ocean, magma from deep in earth's mantle rises toward the surface and pushes 2 or more plates. This is an example called The Mid-Atlantic Ridge.
 * On land it pulls plates apart and like in Iceland.
 * On land, giant troughs such as the Great Rift Valley in Africa form where plates are tugged apart.
