The statement that shows the correct definition of a type of tectonic plate boundary is included in two answers : letter "B" and "C", taking into account that in the two response options the same statement is repeated.
"At a divergent boundary, plates separate".
Explanation:
Divergent boundaries
It occurs when two tectonic plates move away from each other. When these types of boundaries occur, earthquakes are likely to occur and magma (molten rock) leaves the Earth's mantle to the surface. Then it hardens or solidifies and thus a new oceanic crust is created.
Convergent boundaries:
When two plates meet or collide, the impact of collision can cause different reactions: a) cause the edges of one or both plates to buckle into the mountain ranges; or that b) one of the plates bends towards the bottom of the ocean. This type of limits generates chains of volcanoes and earthquakes.
Transformation boundaries:
When two plates that slide together form a limit. The two plates that are found are compensated, divided and transported in opposite directions. The rocks that are in the limit are pulverized. Also, this type of boundary between plates generates earthquakes.
