earthquakes and mountains
12
Which occurs at a convergent plate boundary is called a(n) ___________________________.
slab pull
basal drag
seafloor spreading
ridge push
13
Seafloor spreading is a process that...
destroys oceanic crust
causes continents to plow through the seafloor
occurs at the mid-ocean ridges
