Reverse faults are exactly the opposite of normal faults. If the hanging wall rises relative to the footwall you have a reverse fault. Reverse faults occur in areas undergoing compression. If you imagine undoing the motion of a reverse fault, you will undo the compression and thus lengthen the horizontal distance between two points on either side of the fault.
if you stood on the fault plane the block on the right would be under your feet. this is thus the footwall. The tan sandstone has been pushed up and over itself. This offset of the hanging wall indicates that this is a reverse fault.
D. There are no major fault lines or hot spots close by.
Why?
Because "They don’t occur anywhere else other than along the Ring of Fire" is incorrect, the Ring of Fire is just a place where many volcanoes are.
Because "The composition of the rock in that area is not conductive to eruptions." they type of rock doesn't play that much of a role in the formation of volcanoes
Because "The magma doesn’t have enough silica or gas to form an explosive eruption." It isn't a gass that is found, it is the build up of pressure from fultlines moving and things on the inside of the earth.

The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.
<h3>Meaning of speciation</h3>
Speciation can be defined as a process that births new species with different traits while they evolve.
Speciation occurs when extinction is eminent and most time in other to preserve that race they evolve into something new with new traits.
In conclusion, The idea behind an available niche after extinction leading to speciation is: the fact that those species can grow distinct and then in other to survive develop new traits.
