How are the laws of superposition and crosscutting relationship used to determine the relative age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.
What fault develops in response to horizontal tensional stresses in crustal rocks?
Normal faults develop in response to horizontal tensional stress in crustal rocks. These faults are characterized by the hanging wall moving down relative to the footwall due to stretching and pulling apart of the rocks.
Are both normal and reverse faults caused by tension?
Normal faults are caused by tensional forces pulling rocks apart, leading to the hanging wall moving down relative to the footwall. Reverse faults are caused by compressional forces pushing rocks together, leading to the hanging wall moving up relative to the footwall.

What is the rock age of the normal fault?
The rock age of a normal fault can be determined by analyzing the age of the rocks on either side of the fault. Normal faults typically form in response to extensional forces, where older rocks are uplifted and younger rocks are deposited in the hanging wall. By dating the rocks on either side of the fault, geologists can determine the relative timing of fault movement.
What is the relative age relationship of faults to the rocks they cut?
Faults are younger than the rocks they cut through, as they are formed after the rock units. The offset layers or rocks along a fault help geologists determine the relative age relationship between the fault and the surrounding rocks.
How are the laws of superposition and crosscutting relationship used to determine the relative age of rocks?
They are used to determine the relative ages of rocks by stating that younger rocks lie above older rocks, and that rocks that cut through a layer are younger than the existing layer.
What law do scientists apply to determine relative ages of rocks when the find faults or intrusions?
Scientists use the principle of cross-cutting relationships to determine the relative ages of rocks when they find faults or intrusions. This principle states that the rock being cut must be older than the geological event cutting through it (like a fault or intrusion). By analyzing the sequence of events and their relative ages, scientists can piece together the geological history of a region.
What are the reative age relationship of faults the rocks they cut?
Faults are always younger than the rocks they cut. They cannot be older that the rocks they are cutting, because the rocks would not be there.
Which is used to determine earthquakes risk?
Strains in rocks near faults
Can fossils be used to determine the relative ages of rocks layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
What does faults mean?
Normal faults are when you have hanging walls that slide down relative to and below the footwall. Dip-slip faults are normal faults.
What are breaks in the earth's crust?
Breaks in the Earth's crust are known as faults. They occur when rocks on either side of a fracture move relative to each other. Faults can be created by tectonic forces, leading to earthquakes when the stress becomes too great for the rocks to remain stationary.

What fault develops in response to horizontal tensional stresses in crustal rocks?
Normal faults develop in response to horizontal tensional stress in crustal rocks. These faults are characterized by the hanging wall moving down relative to the footwall due to stretching and pulling apart of the rocks.
When rocks break, they move along surfaces called?
When rocks break, they move along surfaces called faults or fractures. These are planes along which the rock layers have shifted relative to each other due to stress in the Earth's crust. Movement along these surfaces can result in earthquakes.
Are both normal and reverse faults caused by tension?
Normal faults are caused by tensional forces pulling rocks apart, leading to the hanging wall moving down relative to the footwall. Reverse faults are caused by compressional forces pushing rocks together, leading to the hanging wall moving up relative to the footwall.
