the mantel of earths crust will break causing an eartqake
well, a fault pretty much does break or crack along wich rocks move.
It's a road that is not just rocks in a line it's a road made by many machines which makes it smooth and quite flat to drive on.
"The fossils found in this rock layer are older than the fossils found in the layer above it." "The granite intrusion is younger than the surrounding sedimentary rocks." "The volcanic ash layer is slightly older than the layer of soil above it." "The erosion pattern on the hillside indicates that the granite rocks are older than the layers of sediment deposited on top of them." "The cross-cutting relationship between the fault and the layers of rock indicate that the fault is younger than the rock layers it cuts through."
igneous rocks
the rocks are 67576million years old and some of the rocks are 13542million years old.
A normal fault may form when rocks are pulled apart. In a normal fault, the hanging wall drops down relative to the footwall due to tensional forces pulling the rocks apart.
Rocks being pulled apart are under tension. This is found at divergent plate boundaries. It is a tension fault.
a divergent boundry
Rocks on either side of a fault move along the surface of the fault.
Transform fault
a reverse fault
A Transform fault where one tectonic plate slides past another tectonic plate results with rocks being pulled apart. Slippage results when the rock of one plate bends the rock of another, causing elastic rebounds and the release of energy as surface waves.
When compression pushes rocks together, faults form when the stress exceeds the strength of the rocks, causing them to break and push against each other. These fault zones can be areas of high seismic activity as the rocks continue to be pushed and undergo deformation.
Tension creates normal faults, where the hanging wall moves downward relative to the footwall. This type of fault is common in divergent boundary settings when tectonic plates move away from each other, causing extension and the rocks to be pulled apart.
Reverse fault
A reverse fault may form when rocks are compressed.
A crack in the Earth's crust is a fracture where rocks have pulled apart, whereas a fault is a fracture where there has been movement along the fracture plane. In other words, a fault is a type of crack in the Earth's crust that has undergone displacement.
