Guide Questions: 1. How do the boundaries differ from one another? 2. How would the surroundings be affected by these movements? 3. What type of plate boundaries does each figure represent?
Answers 1
Answer:
1.) There are many different types of plate boundaries. For example, sections of Earth's crust can come together and collide (a “convergent” plate boundary), spread apart (a “divergent” plate boundary), or slide past one another (a “transform” plate boundary).
Divergent boundaries: where new crust is generated as the plates pull away from each other. Convergent boundaries: where crust is destroyed as one plate dives under another. Transform boundaries: where crust is neither produced nor destroyed as the plates slide horizontally past each other.
2.) Movement along fault changes the topography of its surroundings. A normal fault would create rift valleys and mid-oceanic ridge. A reverse fault can create a chain of volcanoes, powerful earthquakes, Island arcs, mountain range, large mountain belts. Strike-slip fault would create valley or undersea canyon.
3.) Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
