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?
100
What happens at a convergent tectonic plate boundary?
What is two tectonic plates collide with one another, causing subduction and or mountain building?
100

What are the 3 main types of volcanoes?

What are shield, cone, composite.

200
How is the outer core different than the inner core?
What is the outer core is liquid and the inner core is solid?
200
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?
