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.
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.
When did the christchurch particular fault last move and how can scientists decide this?
The Christchurch earthquake fault last moved significantly during the 2010-2011 earthquakes. Scientists use a combination of geological mapping, GPS data, and monitoring of ground deformation to track the movement of faults over time and determine when they have last ruptured. By examining historical seismic data and studying the distribution of earthquakes along a fault, scientists can also estimate the recurring interval of fault movement.
What two factors help geologists determine earthquake risk?
Two factors that help geologists determine earthquake risk are the history of seismic activity in the region and the presence of active fault lines. By studying past earthquakes and fault lines, geologists can assess the likelihood and potential impact of future earthquakes in a specific area.
How is it known that earthquakes are the result of movement along faults?
Earthquakes are known to be the result of movement along faults because geologists have observed that seismic activity coincides with fault lines. The stress buildup between tectonic plates along these faults causes them to suddenly release energy in the form of an earthquake. Studying the patterns of seismic activity and fault movements helps scientists understand and predict earthquakes.

How can scientists map hidden faults?
By studying how the earth's crust reacts to earthquakes, volcanoes, or underground explosions and the like.

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.

Why do scientists collect data on friction along the sides of faults?
i dont know really
Why do scientists monitor faults?
to detect a slight rise or fall in the elevation and tilt of the land.
Which is used to determine earthquakes risk?
