Warm Up

1. List the three types of volcanoes.2. What effects magma’s viscosity?3. Describe low viscous magma. High viscous magma.4. Which volcano produces the most violent eruptions?5. Which volcano has a short life span?6. What are convection currents and where do they occur?7. Where to plate tectonics take place?

**Did you finish your VOLCANO homework??***Set up NEW cornell notes on the next page! Write your

objective and LEQ!!**

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

LEQ: How do the different aspects of an earthquake determine its severity?

Agenda• Warm-up• Objective & LEQ• Activating Strategy• Notes• Group research• Class presentations• HW: Study for Friday’s quiz

Activating Strategy• 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!)

• Prepare for binder check• Get out volcano half-sheet to be collected

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

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

• http://www.iknowthat.com/mhscience/Earthquakes/earthquake_movie.html

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

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

What is an earthquake?• An earthquake is the shaking of the ground

due to the movements of tectonic plates

What causes an Earthquake?

Along a fault, energy builds up in a rock until it breaks and releases energy.

This release of energy causes an earthquake.

What is the Elastic Rebound Theory?• Gradual buildup, and release of stress and strain,

between tectonic plates which leads to earthquakes

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

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 thecrust where the earthquake occurs, between two blocks of rock that have moved past each other.

What are the parts of an earthquake?

What is a Seismograph

• Records ground movements caused by earthquakes, explosions, or other Earth-shaking phenomena.

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.

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.

Seismic intensity is affected by rock type.

Amplitude of oscillation increasing

What is an Aftershock?

• Smaller earthquake that occurs after a previous large earthquake, in the same area of the main shock.

Earthquake Project• With your partner, read the article provided• You will create a poster that needs to include the following:• Table of information• Diagram of earthquake with the labeled parts (fault, epicenter, focus)• Definitions of the following vocabulary words: aftershock, fault, focus,

epicenter, seismograph• You must include at least 3 colors!!

• Create table on the copy paper which displays the following information about YOUR earthquake:• Earthquake Location• Date of Earthquake• Magnitude• Location of Epicenter• Approximate Deaths• Major destruction and damage

• Draw and label the different parts of an earthquake• You have 15 minutes

Exit Ticket

1. Draw and label diagram which represents an earthquake and its components.

2. What is an aftershock?3. What records ground movements caused by

earthquakes, explosions, or other Earth-shaking phenomena?

4. True or False: Seismic intensity (vibration) is greater on bed rock than on water-saturated sand and mud.

5. True or False: A 7.0 magnitude earthquake will always cause the same amount of damage, regardless of where the earthquake occurs (ex. Haiti vs. California)
