Reverse fault
Reverse Fault
The rocks that are forced up and over the rocks below the fault surface are referred to as "hanging wall" rocks. This occurs in a specific type of fault known as a thrust fault, where compressional forces cause the hanging wall to move upward relative to the footwall, which is the block of rock below the fault surface. This movement can result in significant geological features, such as mountain ranges.
This geological phenomenon is called overthrusting, where older rocks are pushed up and over younger rocks due to tectonic forces. It results in the older rocks being positioned above the younger ones.

Igneous rocks can be found both in the ground and above ground. Igneous rocks form from the cooling and solidification of magma or lava, which can happen below the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks).
Submersion zone, as described in the theory of plate techtonics.
Yes, igneous rocks can be formed both above and below the ground. When molten rock solidifies beneath the Earth's surface, it forms intrusive igneous rocks like granite. If molten rock reaches the Earth's surface and cools rapidly, it forms extrusive igneous rocks like basalt.
Igneous rocks that form below the Earth's surface are called intrusive or plutonic rocks. These rocks cool and solidify slowly, allowing large mineral crystals to form. Examples include granite and diorite.
Igneous rocks can form both above and below the Earth's surface. When magma erupts from a volcano and cools quickly, it creates extrusive igneous rocks, such as basalt, on the surface. Conversely, intrusive igneous rocks, like granite, form when magma cools slowly beneath the surface. Both types result from the cooling and solidification of molten rock.
This kind of fault is called a normal fault and is usually a sign of crustal extension.
nonconformity
Its located above layers of impermeable underground rocks. At or below the water table.
