1.All Earthquakes occur along _________.2.The force exerted when an object pushes, pulls, or presses against another object is called ________.3.Most faults are located along __________ ____________.

Schedule:• 7.1–Types of Faults Notes• 7.2 RSG

Homework:• Read 7.3

Objective: I can understand that earthquakes occur along faults

Types of Faults

Rocks Move Along Faults

• Fault:– Fracture, or break, in Earth’s lithosphere,

where blocks of rock move past each other

• At some parts of a fault, the rock slides slowly or constantly. At others it sticks or locks together. – Rock bends as stress is put on it (the force

exerted when an object presses on, pulls on, or pushes against another object.)

Earthquake

• Earthquake – shaking of the ground caused by the sudden

movement of large blocks of rock along a fault– can occur when there is a sudden release of

stress in the lithosphere.• Release of stress occurs when the rocks break

free from being stuck

• Strength of an earthquake depends on– The amount of stress built up– The distance the rocks move along the fault

The rocks that move

• Most faults are along tectonic plate boundaries– Most earthquakes occur here

• The rocks that move during an earthquake are smaller than tectonic plates

• A small percentage of earthquakes occur along faults within plates– Stress along a plate boundary can cause the rocks to

break and move along weak areas in the middle of the plate.

Types of faults

• Faults are classified base on how they move– How they move is determined by the kind of

stress that they are under.

• More than one type of fault may be present along the same boundary.

Normal Fault• The block of rock above

the fault plane slides down relative to the other block

• Occurs when stress pulls the rocks apart

• Earthquakes are common near boundaries where tectonic plates are moving apart– The Great Rift Valley of

Africa.

Reverse Fault

• The block of rock above the fault plane moves up relative to the other block

• Occurs when stress presses rocks together

• Occurs near collision-zone boundaries between plates

Strike Slip Faults

• Blocks of rock move sideways on either side of the fault plane.

• Occurs when stress pushed rocks horizontally

• Happens when plates scrape past each other

Tuesday, January 8th Entry Task Answer the following questions full sentences, IQIA.1.List the 3 types of faults and briefly explain each.2.Describe the relationships among the focus, epicenter and seismic waves during an earthquake.3.Explain two ways earthquake damage can be reduced.
