1. Do Now! Imagine that you have just received news that Charlotte is preparing for an earthquake. If you had to prepare an emergency kit, what would you include? (Use complete sentences!)

2. Announcements: Unit 3 Test on Friday! Turn in all missing work! Unit 3 Table of Contents: Layers of the Earth foldable Graham cracker lab Volcano Group Jigsaw Earthquake Presentation Notes Locating Earthquakes Worksheet Unit 3 Review + Vocabulary

3. Follow-up: Did you think of these things? First aid kit and instruction booklet Plastic tarp or a small tent Emergency ("space") blankets and one sleeping bag for each family member At least one gallon of bottled water per person, per day. For a 3-day supply, that adds up to three gallons of water per person Enough canned or dried food for 3 days Can opener Flashlight (easily in reach) Battery-powered radio Spare batteries for everything (stored separately in waterproof bags) Toilet paper, soap, toothpaste and toothbrushes, and other personal supplies Multi-purpose dry chemical (Class ABC) fire extinguisher Any important medicine and supplies for infants, elderly people, and others with special needs

4. Exit Ticket-Monday 1.What are the 3 different types of plate boundaries? 2.Next to the 3 different types above, name a land feature that is formed because of the plate boundaries 3.What is viscosity? 4.Name and describe one of the types of volcanoes.

5. Earthquakes! SWBAT describe the anatomy of an earthquake and relate to different types of plate boundaries.

7. Haiti Earthquake example: Haiti, on January 12, 2010Haiti How severe was this earthquake? 7.0 magnitude What happens with a 7.0 magnitude earthquake? What happens What was the aftermath in Haiti?aftermath

8. Japan Earthquake example: Japan, on March 11, 2011Japan How severe was this earthquake? What happens during a 9.0 magnitude earthquake? What happens What actually happened in Japan?actually happened

9. India Earthquake example: India, on September 18, 2011India How severe was this earthquake? 6.8 magnitude What happens? What happens What actually happened?actually happened

10. What is an earthquake? An earthquake is the shaking of the ground due to the movements of tectonic plates

11. ELASTIC REBOUND Along a fault, energy builds up in a rock until it breaks and releases energy. This release of energy causes an earthquake. *Demo: Ruler, Rubber Band

12. Elastic Rebound Hypothesis Definition: the gradual buildup, and release of stress and strain, between tectonic plates which leads to earthquakes

13. What Causes Earthquakes? As tectonic plates push, pull or scrape against each other, stress builds up along faults until the rocks finally move A fault is a break in the Earth’s crust where plates slide, push or pull against each other

14. The epicenter is the location on the surface of the Earth directly above the focus. Surface waves move outward from the epicenter. The focus of an earthquake is the point INSIDE the Earth where the earthquake starts. It is the place below the earth’s surface where the rocks tear, come apart, or collide. The fault is the break in the crust where the earthquake occurs, between two blocks of rock that have moved past each other. Parts of an Earthquake

15. Seismograph The seismograph records ground movements caused by earthquakes, explosions, or other Earth-shaking phenomena.

16. Magnitudes and Energy of Earthquakes Annual Numbers of EQs What’s the message? MOST of the energy is released by around 20 magnitude-7 and larger EQs every year.

17. Seismic intensity is affected by rock type. Amplitude of oscillation Form a hypothesis about how would you expect the houses to react during an EQ.

18. Seismic intensity is affected by rock type. Amplitude of oscillation increasing

19. Aftershock An aftershock is a smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.

20. Group Presentations RULES: Listen to directions, arrange desks for group work, and have one student read aloud the article. Once finished, students will quietly discuss their article with one another and decide who will present what information. Each group will receive a packet of information. This packet contains information about an earthquake that has occurred in the past. Your group is responsible for explaining the following information to the class about your earthquake: focus, epicenter, magnitude, and damage recorded. Each group member must present at least one piece of information for the table speaking loudly and clearly so that the class can hear
