A type of plate boundary that when two plates are moving toward each other it is called?

It acts against the driving force of tectonic plates.

It occurs between two colliding plates whereby both plates are suck down by convection current.

The immediate concerns about transform fault boundaries are  ___________activities triggered by movements along the fault system.

He proposed a theory that about 200 million years ago, the continents were once one large landmass. 

When plates slide past another frictional force prevents the action of ridge push is called?

The process that allowed the creation of new bodies of water is called?

As an oceanic crust moves away from a divergent boundary, it becomes denser than the newer oceanic crust. 

It is made of a variety of solid rocks like sedimentary, metamorphic, and igneous.

Breaks in Earth’s crust where rocks have slipped past each other is called?

As the oceans plates move further and further apart, new ocean floor is continuously added it is called?

When to two plates move away from each other create a gap or rift between them it is called?

According to Wegener, South America and Africa fit together; India, Antarctica, and Australia match one another; Eurasia and North America complete the whole continental puzzle in the north

The East Pacific Rise is one of the most active sites of seafloor spreading, with more than 14 centimeters every year.

Coal in South America and South Africa are very similar in terms of their sequence and share common ancestors.

During convergent plate boundary,  a large group of tall mountains can be formed.

Most divergent boundaries are situated along underwater mountain ranges called oceanic ridges.
