how many types of plate movements are there? describe each one of them.
Answers
Answer:
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench. A chain of volcanoes often forms parallel to convergent plate boundaries and powerful earthquakes are common along these boundaries.
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon. Earthquakes are common along these faults. In contrast to convergent and divergent boundaries, crust is cracked and broken at transform margins, but is not created or destroyed.
Explanation:Please mark it brainliest
There are three type of movements associated with the plate boundaries such as divergent, convergent and transform boundaries.
Explanation:
- The convergent boundary is where the plates collide with each other and are considered to be destructive plate margin while the divergence that is spreading apart or away from each other created new boundary as the lava's upwells from the seafloor
- The transformed boundary is one that moves in a horizontal direction that is pates rub side past one another and their rate of movement is 3 to 5 inches per year.
