Question

woulktion Series, the most stable minerals that create soil on Earth's now at: 1) the highest temperatures & highest surface would be those that form pvessures 2) the lowest temperature temperatures sowest pressures 3) the lowest pressures As distance from the rock source area increases, the degree rounding 14. As distanc increases inera ncreases 2) decreases 3) remains the same 4) depends p rock is found to have large rounded fragments of many sizes 1) sandstone 2) arkose 15.A sedimentary o.cemented together. This rock would be classified as 3) conglomerate 4) limestone 16. Which of the following are NOT considered sedimentary rock cementing materials? 1) quartz 2) calcite 3) iron oxides 4) olivine. 17. The basic structural characteristic of sedimentary rocks would be: 1) cross-bedding 2) mudcracks 3) ripple marks 4) stratification. 18. Lithification of sedimentary rocks involves: 1) deposition 2) 3) cementation 4) all of these. 19. Which of the following sedimentary rocks contains NO minerals? 1) shale 2) breccia 3) greywacke 4) coal. 20. Shale is found in a rock exposure. This means its environment of deposition was most 21. The sedimentary rock that forms under evaporating shallow seawater conditions 22. Symmetrical ripple marks indicate which type of environment? 1) an old river bed likely a: 1) beach 2) lake or swamp 3) river 4) desert. would be: 1) sandstone 2) shale 3) halite 4) arkose. 2) an old beach 3) an evaporating lake 4) a swamp. 23.A sandstone sedimentary rock outcrop is found to have giant cross-beds and footprints of dinosaurs. This environment was formerly: 3) an ocean 4) a desert. 1) a lake 2) a river 24. Which of the following sedimentary rocks would be classified as a biochemical rock? 4) coal. 1) shale 2) breccia 3) greywacke 25. Mudcracks are typically associated with what environment of deposition? 1) beacth 26. The most abundant mineral in a sandstone would be: 1) quartz 2) feldspar 3) mica 27. Which of the following is a mono-mineralic sedimentary rock? 1) arkose 2) shale 2) deep ocean 3) desert 4) all of these. 4) clay 3) limestone 4) coal

Explanation / Answer

13. Lowest temperatures and lowest pressures (Since the surface pressure and temperature is lower compared to under the surface)

14. Increases (the more distance of transport, more roundness)

15. Conglomerate

16. Olivine (it is not stable on the surface where most of the sedimentary rocks are found)

17. Stratification (the sediments accumulate layer by layer over time)

18. All of these (first is deposition, then compaction and then cementation)

19. Coal (pure carbon)

20. Lake and swamps

21. Halite

22. An old river bed

23. A river

24. Coal (remains of plants)

25. Desert (other areas have a flow of water which would not form mudcracks)

26. Quartz

27. Limestone (Calcium Carbonate)
