4.20 Unit Test: Plate Tectonics - Part 1 | Baamboozle - Baamboozle

According to the theory of plate tectonics, how do two plates interact to form Earth's largest mountain ranges?

collide

create new plates

scrape past each other

move apart

What happens at a convergent boundary?

Collisions occur as lithospheric plates move toward each oth

Magnetism occurs as lithospheric plates are attracted toward

Earthquakes occur as lithospheric plates move away from each

Mountains form as lithospheric plates move side by side past

Which phrase best describes of a convergent boundary?

plates that move toward each other

plates that are attracted to each other by gravity

plates that move away from each other

plates that move side by side past each other

At which type of boundary do lithospheric plates collide?

convergent boundaries

gravitational boundaries

contour boundaries

convection boundaries
