1. Warm Ups 2

2. #1 - 9/2/15  What’s the difference between strata and foliated?  Sedimentary rocks can have sediment in layers called strata.  Foliated metamorphic rocks have flattened mineral grains that can look like bands.

3. #2 – 9/3/15  Place the steps of sedimentary rock formation in order:  Cementation, deposition, erosion, weathering, compaction  WEDCC

4. #3 – 9/4/15  You found an rock with a fish fossil in it at the top of a mountain. What kind of rock is it and how did it get there?  Organic sedimentary – The fish died there when the mountain was once underwater.

5. #4 – 9/8/15  ____________ is the process that forms sediment when _________, _________, heat, and ice break rocks into tiny fragments.  Weathering, water, wind

6. #5 – 9/9/15  _______________ forms deep underground when any type of rock is exposed to intense heat and ______________.  Metamorphic rock, pressure

7. #6 – 9/14/15  Mechanical weathering is when rocks are physically broken into smaller pieces. List 3 ways this can happen.

8. #7 – 9/15/15  Make a hypothesis:  If we dissolve a large piece of sugar and the same mass of crushed sugar, then I think the __________ will weather faster because ______.  Use the words “volume” or “surface area” to explain why this happened.

9. #8 – 9/16/15  Choose 1 of the following factors and explain how it causes differential weathering of rocks:  surface area vs. volume  hardness  climate

10. #9 – 9/17/15  Devil’s Tower in Wyoming used to be a volcano before it weathered. Use “differential weathering” to explain how it formed.
