A divergent boundary is when two plates separate. The type of stress a divergent plate has is tension. Some of the famous divergent plate boundaries are Mid-atlantic ridge, East Pacific rise, and East African rift valley. The landforms divergent plate boundaries make are mid-ocean ridge, Volcanos , Earthquakes, Faults and Rift valley.
Pompeii, this is an example of a real world disaster. Mount. Vesuvius destroyed the city of Pompeii is the year 79 AD. This disaster covered the city of Pompeii in a thick carpet of volcanic ash thousands of people died and the city was abandoned.
Transform plate boundaries
A transform boundary forms where two plates separate. The type of stress a transform plate boundary has is shear stress. The type of landform transform plate boundary creates is a fault.
A real world example of a transform plate boundary is the San Andreas fault. The San Andreas fault zone, which is about 1,300 km long and in places tens of kilometers wide, slices through two thirds of the length of California. Along it, the Pacific Plate has been grinding horizontally past the North American Plate for 10 million years, at an average rate of about 5 cm/yr. Land on the west side of the fault zone (on the Pacific Plate) is moving in a northwesterly direction relative to the land on the east side of the fault zone (on the North American Plate).
Convergent plate boundaries
A convergent plate is form where two plates collide. The type of stress a convergent plate boundary has is Compression. The landforms a convergent boundaries makes are mountain ranges, and high plateaus.
The grand canyon is a real world example of a convergent boundary. This is how the Grand Canyon was formed. About 80 million years ago the Pacific plates slid under the North American plate. That creating the rocky mountains, which forced the uplift of the Colorado plateau. The mighty Colorado river flowing over the already rising plateau creating a deep groove in which the river could not escape. The river cut into the Colorado plateau which created the Grand Canyon it took 4 million years to create the Grand Canyon and it is still growing.
