Entry Task: Monday, January 5th Get out a separate piece of paper. You will be taking 15 notes on the movie. This will be turned in on your way out the door. Clear everything off your desk except the notes paper and a writing utensil. Schedule: • Deadliest Earthquakes Video Objective: I can understand the effects of earthquakes Homework: • Bring in Structure if you didn’t today Entry Task Tuesday, January 6th Write down the entire sentence and fill in the blank with the correct term Schedule: • Types of faults notes • Earthquake Faults Questions Objective: I can understand the different types of faults 1. All Earthquakes occur along Homework: _________. 2. The force exerted when an • 7.2 Questions. Page 234 #16. Use full sentences, IQIA. object pushes, pulls, or presses against another object is called ________. 3. Most faults are located along __________ ____________. 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 collisionzone 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 Earthquake Faults Questions • Answer questions 1-6 from page 225. • Do this in your notebook, using full sentences, IQIA. Wednesday, January 7th 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.
