∙ 12y agoFault scarp: A steep slope resulting from the movement of rock strata
Slickensides and slickenlines: Slickensides refer to the smoothly polished surface caused by frictional movement between rocks on the two sides of a fault, while slickenlines are groove marks on fault surfaces, slickensides, produced by the rubbing forces of the two sides of the fault.
Fault breccia: angular fragments of rock resulting from the frictional movement on fault zones.
Straight rivers and a long line of green vegetated area: since faulting is accompanied by friction between the two sides of the fault, the rocks at the fault zone are commonly pulverized, fragmented and weakened. As a result, running water from streams and rivers would tend to flow along the fault zone because that is the place where rocks are weaker to erode. Moreover, groundwater usually finds its way to the surface along the openings created by faults. Hence in areas where there are fault lines we also see plants flourishing, because they are close to groundwater source. Thus, exceptionally straight flowing rivers and streams or long lines of vegetated areas are evidence of the presence of a fault.

What two factors help geologists determine earthquake risk?
Geologists can determine earthquake risk by locating where faults are active and where past earthquakes have occured.
Geologists know that wherever plate movement stores energy in the rock along faults?
earthquakes are likely
What concerns do geologists have about future field reversals?
None, not much we can do about it.
Why do geologists need to work backward when studying rocks from the field?
They are just cool like that
What can help a geologist determine the earthquake risk for an area?
Geologists can determine the risk for an earthquake by measuring the seismic waves along faults as well as friction using a seismometer.
How do geologists monitor faults?
to monitor faults, geologists have developed instruments to measure changes in elevation, tiliting of the land surface, and ground movements along the faults. Geologists use tiltmeters, Creep Meters, Laser- Ranging Devices, and GPS Satellites.
Why do geologists collect data on friction along the sides of faults?
Geologists collect data on friction along the side of faults so that they can predict how much pressure is applied on the faults so they can predict how strong the earthquake is.
What is used to detect hidden faults?
Geologists can use seismographs to detect hidden faults. When seismic waves encounter a fault, they are reflected off of the fault. Geologists can use this information to chart the location of a depth of a hidden fault.
What are three ways in which geologists use seismographs data?
They map faults, detect changes along faults, and develop a method of predicting earthquakes

Are earthquakes be predicted How?
They can't be predicted and that is the problem. Geologists monitor active faults for signs of movement.
Why geologists collect data on friction along the sides of faults?
So that geologist can predict how much force of pressure applied on the faults to predict how strong the earthquake.
Geologists know that wherever plate movement stores energy in the rock along faults?
earthquakes are likely
What factor help geologists determine earthquake risk for a region?
The factors that help geologists determine for earthquake risk for religion are the movement of seismic waves along faults and friction.Hope this helped!
What factors do geologists take into account when determining earthquake risk?
The movement of seismic waves along faults and friction.
What do faults tell geologists about the relative ages of rock?
A fault must be younger than the rock it cuts through.
