Even though no new crust is created or destroyed there are still hazards. Deep, or shallow earthquakes are very common. These can lead to mud and land slides. These also produce faults and an example of one would be the San Andreas Fault. In America you can find a transform boundary where the Pacific plate slides past the North American plate.
The last type of plate boundary is the transform boundary. This is when two tectonic plates slide past each other. Lithosphere is neither created nor destroyed.
Plate Tectonics Movement
Ridge push is when the cooling lithosphere sinks, and the asthenosphere moves away from the sinking lithosphere causing push on the bottom of the plate. Slab pull is when he leading edge of the plate sinks, it pulls the rest of the plate along without it.
Convection is the process where less dense material rises and more dense material sinks due to a heat source. In the mantle this heat source is the core. The material is the molten rock. The liquid like mantle that is heated, slowly moves and spreads the crust into plates. The heat transferred to the lithosphere is how the plates move. The cooler material will sink and heated will rise, and the process continues.
Real World Experience
The plate we live in is the North American Plate. The bordering plates of the U.S. are the North American Plate, Pacific Plate, and Eurasian Plate. Some dangers we should be alert for are earthquakes, volcanoes, and tsunami's but these may not happen for a while because it is a very slow process. Problems I anticipate are major/deadly earthquakes and huge tsunami's due to the movement of plate tectonics.
Thanks for listening! See you in class again tomorrow!
