Whose Fault Is It? By: Drew, Shaun C, and Evan
Normal Faults • Normal faults are formed by one rock slipping down by gravity and the other part of the rock getting pushed up forward. • Earthquakes are common in a fault line area. • Such as in the Great Rift Valley of Africa. • In a normal fault line the line is nearly vertical. • A normal fault line is made when rocks push together.
Reverse Faults • Formed when two plates push together • One plated slides up and the other slides down • Opposite of a normal fault • They slide up each other almost vertical • Near the Himalayas is a reverse fault that causes lots of earthquakes.
Strike Slip Fault A strike-slip is formed when plates scrape past each other. An example is the San Andreas Fault. When a strike-slip is happening it builds up a lot of friction. If there is enough friction the two blocks will lock together. When they are locked, the plates build up potential energy. When they disconnect, the potential turns into kinetic energy. There are many changes in the rock well under where the fault happened.
What is under Horizon? We come to believe that the Strike Slip fault Line is under Horizon. We come to this conclusion because this fault line has all the characteristics of a Strike Slip. Like the area of Horizon has been having a lot of earth quakes lately. Also they seem to be scraping each other very very slowly.
