Unit 5: Earthquakes & Volcanoes Two week unit! Week 1: Earthquakes Week 2: Volcanoes
Tiers 3 categories: Deformation, Earthquakes, and Volcanoes Your tier 3 will incorporate language arts and science! Dates to Enter • Tier 2 Earthquakes : 11/9 • Tier 1 E and V: 11/13 • Tier 3: 11/16
Keep track of when things are due!! Remember: Tier 1 completion grade Tier 2 and 3 will use a Rubric Project Due Dates
You will get Wednesday Vocabulary Sheet
Where’s My Outline? • You will make your own for a review activity in class!

Group Discussion Try to think of 3 words that go with Earthquakes!
All you need to know about Deformation and the Earth’s Changing Surface! Coffee Talk
Earth’s Changing surface I. Crust – the surface layer of the earth • Continental: land not under the oceans • Average of 32km, but can be as thick as 70km II. Oceanic • Ocean floor • Average of 8km thick Review: Which one is denser?
III. StresS a. The forces that pull and push on the earth’s crust b. Causes deformation – the tilting, breaking or folding of rock
i. Compression Compression – squeezes the rocks of the crust, decreasing volume, increasing density Think: Covergent
ii. Tension Tension – pull the rocks of the crust, increasing volume, decreasing density Think: Divergent
iii. Shearing Shearing – the crust being pushed in opposite directions causing the rocks to tear and twist Think: transform
Review #1. Match the set of arrows to the 3 stress • Shearing • Tension • Compression
Fractures and Faults c. Fracture – cracks in rocks d. Fault – crack along which rocks move sideways, up, or down. • Fault block mountains form from the normal faults pushing up rock • Rift valleys form when land between normal faults slide down
Folding e. Folding – a bend in the rock i. Anticline – an upward fold ii. Syncline – a downward fold iii. Appalachian mountains are made from folds
f. Factors that affect faulting or folding i. Higher temperatures will cause folding/lower temps. cause faulting ii. Greater pressure causes folding/lower pressure causes faulting Rock type iii. Brittle rock will more likely fault iv. Ductile (bendable) rock will more likely fold v. Pressure applied gradually will cause folding/fast will cause faulting
Review #2 What’s the difference between anticline and syncline folding?!
Tier 1 DeformationCOMPLETION Option 1 Words Stress Folding Faulting Anticline Syncline Temperature and folding Rock type and folding Compression Tension Shearing Fracture Due WEDNESDAY Option 1: Flashcards-Use textbook Option 2: Read textbook section on stresses of the Earth starting on page 213.
