Plate Boundaries Flashcards
What are the three main types of plate boundaries?
Divergent, convergent, and transform boundaries.
True or False: Divergent boundaries are characterized by plates moving away from each other.
True
Fill in the blank: Convergent boundaries are characterized by plates moving __________ each other.
towards
At which type of plate boundary do earthquakes commonly occur?
Transform boundaries
What is the process at divergent boundaries where new oceanic crust is formed?
Seafloor spreading
What is the name of the boundary where two plates slide past each other horizontally?
Transform boundary
What geological feature is commonly formed at convergent boundaries?
Mountain ranges
True or False: The Himalayas were formed at a divergent boundary.
False
What is the name of the supercontinent that existed around 300 million years ago?
