Thursday, November 12, 2015 HOMEWORK: Flash cards- reverse fault, normal fault, strike slip fault OBJECTIVE: I will be able to describe and explain the 3 major faults and how they relate to stress. DO NOW: What are the three types of stress? What are the three types of plate boundaries? How do they compare to each other?

Do Now What are the three types of stress? Tension, Compression, Shearing What are the three types of plate boundaries? Divergent, Convergent, Transform How do they compare to each other? Divergent boundaries form from Tension, Convergent boundaries form from Compression, and Transform boundaries form from Shearing.

Document #2 - Faults Fault – a break in the rock of the crust where rock surfaces slip past each other because of stress 3 types of faults: normal fault, reverse fault, strike-slip fault I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Document #2 - Faults Hanging wall – the block of rock that sits over the fault –Diagram: Foot wall – the block of rock that lies under the fault –Diagram: I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Identify the foot wall and hanging wall Foot Wall Hanging Wall

Document #2 - Faults Normal fault: –The hanging wall slides downward, caused by tension in the crust –At divergent boundaries –Example: Great Rift Valley of Africa –Slide down slide normal I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Normal fault: I will describe and explain the 3 major faults and how they relate to stress through a class discussion Doc #6 - Fault Diagram Trick

Document #2 - Faults Reverse fault: –The hanging wall slides upward, caused by compression in the crust –At convergent boundaries –Example: Rocky Mountains –Go up a slide in reverse I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Reverse fault: I will describe and explain the 3 major faults and how they relate to stress through a class discussion Doc #6 - Fault Diagram Trick

Document #2 - Faults Strike-Slip fault: –Rocks on either side move past each other sideways with little up or down motion, cause by shearing in the crust –At transform boundaries –Example: San Andreas fault I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Document #2 - Faults Strike-Slip fault: I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Complete Figure 2 I will describe and explain the 3 major faults and how they relate to stress through a class discussion

Use your notes to complete your foldable. 1.Draw arrows to show how plates move at each boundary, types of stress and 3 types of faults. Label each fault next to drawing 2.For each fault type in your book draw the hanging wall and foot wall and the direction the hanging wall moves for each fault type. Label each fault next to drawing.

Normal Fault – Divergent Boundary – the arrows move apart. (Ex.Sierra Nevadas) [TENSION] Reverse Fault – Convergent Boundary – the arrows move towards each other. (Ex. Himalaya Mountains) [COMPRESSION] Strike Slip Fault – Transform Boundary – the arrows slide past each other (Ex. San Andreas Fault) [SHEARING]

Identify the fault Log on to TeacherWeb and Click on the PowerPoint “Identify the Fault” See if you can identify the types of fault shown in the pictures on each slide. Write the answers on your paper.

Plate Boundaries Stress Faults a break in the rock of the crust where rock surfaces slip past each other because of stress a force that acts on rock to change its shape or volume a boundary between two tectonic plates in which they interact

DivergentTension Normal Foot Wall Hanging Wall (Ex.Sierra Nevadas Ex. Great African Rift Valley)

Convergent Compression Reverse Foot Wall Hanging Wall (Ex. Himalaya Mountains Ex. Rocky Mountains)

Transform Shearing Strike-Slip (Ex. San Andreas Fault)

USE YOUR FOLDABLE BOOK to answer: Which type of fault is caused by tension? What kind of stress causes a reverse fault? Which kind of stress causes a strike-slip fault?

Use Foldable Which type of fault is caused by tension? (normal fault) What kind of stress causes a reverse fault? (compression) Which kind of stress causes a strike-slip fault? (shearing)
