Why is the faulting most likely to occur near the earth surface and not deep within the earth?
There are two reasons. First, faulting is a form of brittle failure, which generally occurs at lower temperatures. Deep in the crust, where it is very hot, rocks tend to undergo ductile failure, deforming like taffy. Additionally, most materials resist breaking at higher overall pressure.

Why is faulting more likely to occur near the surface than deep within the earth?
In geology, faulting refers to the brittle failure of rock masses. This means that they lose cohesion (break into more than one piece) and that a fracture or fractures form through the material. In geology a large fracture which displays relative motion of the rockmass on either side is known as a fault. Faulting occurs where strain rates are large (this means that the material deforms or changes shape quickly) and there are relatively low temperatures and confining pressures at shallower depths within the Earth's lithosphere. These conditions allow fractures to propagate through the rock causing faulting. As the depth within the Earth increases, the confining pressure and temperature will increase (asthenosphere and mesosphere). Both of these factors act to stop the formation of fractures within the material. This means that brittle failure can not occur and instead leads to ductile deformation which is why the rocks fold rather than fracture so faults are not formed at greater depths.
How does faulting of the earth's layer occur?
Faulting of the Earth's layers occurs when stress builds up within the crust, leading to the rock breaking and sliding along a fault plane. This movement releases energy in the form of an earthquake. Faulting can happen due to tectonic plate movements, volcanic activity, or regional stress within the Earth's crust.
Where are you if you are 100km below the surface?
If you were 100 km below the surface you would be in the upper mantle / asthenosphere.
If granite within earth melts and then erupts at the surface what type of extrusive rock is likely to form?
If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
How earthquakes have changed the surface and atmosphere of the earth over millions of years?
EARTHQUAKES have changes the earth in many ways. The folding and faulting of the earth crust have left big cracks in the earths crust. The folding and faulting only happen on the tectonic boundaries. TECTONIC BOUNDARIES: The plates that make up the earths contents.
Folding and faulting are caused by?
Folding and faulting are caused by tectonic forces within the Earth's crust, primarily due to the movement of large plates that make up the Earth's surface. Folding occurs when rock layers are compressed and bent, while faulting happens when rocks break and slide along fractures in the Earth's crust.

Shock waves that are felt on the earths surface as the result of faulting in the Earth's crust?
earthquakes :)
How do faulting and folding change the appearance of the earth's surface?
It forms mountain ranges, plateaus, valleys, and etc.

How have convection currents changed the surface of the earth?
Convection currents occur in the semi-molten mantle. They are created by heat within the earth. As the mantle heats, the rock rises. When it cools, it sinks back down. This movement causes changes in the surface of the Earth.
What is diastrophism?
Diastrophism is the general term for faulting and folding within the crust, the deformation and movement of the solid rocks of the Earth.
Shock waves that are felt on the earth's surface as the results of faulting in the crust are called?
Seismic waves or tremors
Where are you if you are 100km below the surface?
If you were 100 km below the surface you would be in the upper mantle / asthenosphere.
What is the Movement within the earth that cause buried rock to be exposed at the earths surface?
The movement within the Earth that causes buried rock to be exposed at the Earth's surface is called uplift. It refers to the vertical elevation of the Earth's surface.

If granite melts and then erupts at the surface, it is likely to form rhyolite, which is an extrusive rock. Rhyolite has a composition similar to granite but is formed from the rapid cooling of magma at the Earth's surface.
What kind of faulting would you expect to find in the lithosphere if the Earth was contracting?
If the Earth was contracting, you would likely observe compressional or reverse faulting in the lithosphere. This is because as the Earth's size decreases, it can cause the crust to be pushed together, resulting in compression and the formation of reverse faults where the hanging wall moves up relative to the footwall.
