3 Types of Plate Boundaries

╰┈➤ The first type of plate boundary is convergent boundaries. A convergent plate boundary is where one of the tectonic plates submerge under the other. This could happen with multiple plates but in the diagrams shown there are only two.
╰┈➤When the ocean plate is pushed under the continent plate and goes into the mantle. The area of the plate going into the mantle is called the subduction zone. Finally when the continent plate is pushed up onto the ocean plate it creates a very significant subduction trench along the shore and a mountain range on top.
╰┈➤When an ocean plate is pushed under another ocean plates it goes right into the mantle and also has a subduction zone. ╰┈➤ Also when these plates converge a trench is created underwater.
╰┈➤When two continental plates push into each other neither of them submerge instead the crust tends to push upwards or sideways. When pushed upwards it creates mountain ranges and high plateaus.

╰┈➤The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks. In this way, new crust is formed along the boundary. Earthquakes occur along the faults, and volcanoes form where the magma reaches the surface.
╰┈➤One of the most famous transform plate boundaries occurs at the San Andreas fault zone, which extends underwater.
╰┈➤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.
