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.
Earthquakes can cause tsunamis because the moving ocean floor displaces water, causing it to build into waves. Photo: CC0 Creative Commons. In a subduction zone, the location where two tectonic plates meet and one is forced underneath the other, large sections of the Earthâs crust might get consumed.
