Where does seafloor spreading occur?
Seafloor spreading occurs at mid-ocean ridges
What is the process in which the denser oceanic plate moves underneath the less dense continental plate.
Subduction
What is it called when at a transform plate boundary the rocks break and cause the plates to move.
Fault
What geologic feature forms at a divergent plate boundary when two pieces of oceanic crust separate?
Mid-Ocean Ridges
Why is East Africa going to be its own island in millions of years?
East Africa is slowly pulling away from the rest of the continent because the plates are moving apart.
Which two tectonic plates are separating that are forming the East African Rift Valley?
African Plate and Somali Plate
Explain how the Himalaya Mountains formed.
The Himalaya Mountains formed when two continental plates collided.
What frequently occurs at a transform plate boundary?
earthquakes
What two geologic features form at a convergent plate boundary when one piece of continental crust moves together or converge with a piece of oceanic crust?
Ocean trenches and volcano mountain ranges
Explain the process of subduction.
Subduction occurs when the denser oceanic plate moves underneath the less dense continental plate.

What two geologic features form at a convergent plate boundary when one piece of continental crust moves together or converge with a piece of oceanic crust?
Ocean trenches and volcano mountain ranges
Why is the Atlantic ocean getting larger/wider?
The Atlantic is getting larger due to seafloor spreading at its mid-ocean ridges
