What is a geologic features such as faults and igneous intrusions are younger than the rocks they cut through called?
Geologic features such as faults and igneous intrusions that are younger than the rocks they cut through are referred to as "younger features" in the context of relative dating. This concept is based on the law of cross-cutting relationships, which states that if a geological feature cuts through another, it must be younger than the feature it disrupts. This principle helps geologists determine the relative ages of various rock formations and geological events.
How do you determine the relative age relationship of faults to the rocks they cut?
Relatively, they are younger than the rock they cut through.
How can you tell what layer of rock is oldest or youngest?
In undisturbed rock layers, the principle of superposition states that the youngest rock layers are on top and the oldest are at the bottom. This means that the rock layer closest to the surface is the youngest, while the layer at the bottom is the oldest. Additionally, the principle of cross-cutting relationships helps determine relative ages by looking at how faults and intrusions cut across rock layers.
What are the types of faults that lead to earthquakes?
The main types of faults that lead to earthquakes are normal faults, reverse faults, and strike-slip faults. Normal faults occur when the hanging wall drops down relative to the footwall, while reverse faults happen when the hanging wall moves up relative to the footwall. Strike-slip faults involve horizontal movement along the fault.
Explain how physical features are used to determine relative age?
physical features are tilting,faults,intrusion and folding also, using superposition as long as u know which order these go by u can figure out relative age of a rock
How are faults intrusions and extrusions similar?
Faults, intrusions, and extrusions are all geologic features related to the movement of the Earth's crust. Faults are fractures along which rocks have moved, intrusions are igneous rocks that have been forced into pre-existing rocks, and extrusions are igneous rocks that have been extruded onto the Earth's surface. They all involve the movement and displacement of rocks, contributing to the shaping of the Earth's crust.
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 three types of clues to the relative age of rock layers other than the law of superposition?
Fossil succession: Examining the types of fossils found in rock layers can help determine their relative age as different life forms existed during different time periods. Cross-cutting relationships: If a rock layer is cut by another geological feature like a fault or intrusion, the feature is younger than the rock layer it cuts across. Unconformities: Gaps in the rock record due to erosion or non-deposition can indicate periods of missing time and help establish relative ages of rock layers.
What can scientists determine by studying folds faults and intrusions in rock?

How do you determine the relative age relationship of faults to the rocks they cut?
Relatively, they are younger than the rock they cut through.
What does normal faulting mean?
Normal faults are when you have hanging walls that slide down relative to and below the footwall. Dip-slip faults are normal faults.
How can you tell what layer of rock is oldest or youngest?
In undisturbed rock layers, the principle of superposition states that the youngest rock layers are on top and the oldest are at the bottom. This means that the rock layer closest to the surface is the youngest, while the layer at the bottom is the oldest. Additionally, the principle of cross-cutting relationships helps determine relative ages by looking at how faults and intrusions cut across rock layers.
What are the types of faults that lead to earthquakes?
The main types of faults that lead to earthquakes are normal faults, reverse faults, and strike-slip faults. Normal faults occur when the hanging wall drops down relative to the footwall, while reverse faults happen when the hanging wall moves up relative to the footwall. Strike-slip faults involve horizontal movement along the fault.
Normal and reverse faults are characterized mainly by?
Normal faults are characterized by the hanging wall moving down relative to the footwall, while reverse faults are characterized by the hanging wall moving up relative to the footwall. Both faults are caused by compressional forces in the Earth's crust, but their movements are opposite in direction.
Explain how physical features are used to determine relative age?
physical features are tilting,faults,intrusion and folding also, using superposition as long as u know which order these go by u can figure out relative age of a rock
Faults are important because?
Faults are important because it can move the blocks relative to each other. And they can have a major influence on the shaping of the landscape.
