The most dense layer of the atmosphere is the troposphere is the most dense layer because it is at the bottom of the atmosphere. The troposphere is where all our weather happe â¦ ns. It also has the highest air pressure. But more specifically, the earths atmosphere is most dense at the surface.
Earthquakes on faults like these may cause tsunamis in the Puget Sound region. 'Deep' faults Deep faults can occur where two tectonic plates collide and one of the plates is forced beneath the other.
There are three different types of faults: Normal, Reverse, and Transcurrent (Strike-Slip). 1  Normal faults form when the hanging wall drops down. 2  The forces that create normal faults are pulling the sides apart, or extensional. 3  Reverse faults form when the hanging wall moves up.
