Most divergent boundaries lie under the world's oceans. Which of these is a process that occurs at divergent boundaries: subduction of old crust, formation of new crust, plates slide past each other, or continental collisions occur?
What is formation of new crust?

Scientists think continents were once a large single landmass that broke apart and then the continents slowly DRIFTED to their present locations. What is the name given to this hypothesis?
What is continental drift?

Subduction is one plate pushing underneath another plate. If an oceanic plate and a continental plate collide, which one will push underneath the other one and why.
What is the oceanic plate will push under because it is denser?
