Warm Ups 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.
#2 – 9/3/15 Place the steps of sedimentary rock formation in order: Cementation, deposition, erosion, weathering, compaction WEDCC
#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.
#4 – 9/8/15 ____________ is the process that forms sediment when _________, _________, heat, and ice break rocks into tiny fragments. Weathering, water, wind
#5 – 9/9/15 _______________ forms deep underground when any type of rock is exposed to intense heat and ______________. Metamorphic rock, pressure
#6 – 9/14/15 Mechanical weathering is when rocks are physically broken into smaller pieces. List 3 ways this can happen.
#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.
#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
#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.
#10 – 9/29/15 Draw a picture of 3 river rocks that have been exposed to different amounts of time of abrasion. On your neighbor’s sheet, label their rocks 1 – least amount of abrasion 2 – medium amount of abrasion 3 – most amount of abrasion
#11 – 9/30/15 Soil’s fertility is how well it can hold water and nutrients. Describe the kind of soil farmers like best to grow their crops in.
#12 – 10/5/15 Weathering happens faster in climates that are ___________ and __________. An example of this type of place is _____________.
