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.
Faults: 3 major categories â¢ normal faults-caused by extension or tensionâ¢ thrust faults and reverse faults-caused by compressionâ¢ strike-slip or tear faults-caused by lateral shear. Normal fault Thrust fault Strike-slip fault. In both normal and reverse faults the hanging wall is above the footwall.
