Sequence the 5 steps of the formation of a sedimentary rock. #1 is first; #5 is last. _____ cementation _____ erosion ______ compaction ______ weathering ______ deposition _______22. Sedimentary rocks are classified into the 3 groups (clastic, chemical, organic) by: A. B. C. D. texture hardness how they form (what it’s made of). crystal size ________23. Which of the following clues would lead you to classify a rock as sedimentary? A. B. C. D. layers of sediment. fossils found within the rock. mud cracks and ripple marks. All of the above. Types of Sedimentary rocks: chemical clastic organic 24. A rock that is made of material that was once living is a(n) _________________________________ sedimentary rock. 25. A rock that forms when water evaporates and leaves minerals behind is a ________________________ sedimentary rock. 26. A rock made of broken fragments or pieces is a ________________________________ sedimentary rock. 27. Fill in the following table: Type of Igneous rock Where does it form? Crystal size? Example? Intrusive Extrusive ________28. Rocks are classified into the three major groups (igneous, sedimentary, metamorphic) by: A. B. C. D. physical properties hardness how they form density 29. True or False: _____________ All 3 rock types (igneous, sedimentary, metamorphic) can become a metamorphic rock. _______ 30. Which factor(s) can cause mechanical weathering? A. B. C. D. ice wedging (water freezing in cracks) abrasion (grinding away by water & wind) animal action (burrowing/digging) all of the above _______ 31. Burrowing animals contribute to the development of soil because they: A. B. C. D. mix the soil when digging. leave holes for air and water to get in. add organic material when they die and decay. all of the above. _________ 32. What is the very first step in soil formation? A. B. C. D. weather rocks mix with organic material. a layer of humus forms on top of soil profile. weathering breaks down parent rock into small pieces. decomposers break down organic matter. Below is a scenario. Read it carefully and answer Questions #33-39. A. Shara wanted to find out if flowers grew faster with sugar in the water. B. She believed the sugar would make the flower grow faster. C. Shara filled 4 jars with 200 ml of water.
