1 Earth Science CRCT Review

2 1. Topographic maps are primarily used to show which of the following features? A the shapes of continents and oceans B lines of latitude and longitude C highways and other roads D the shape and size of surface features

3 Use the map to answer question Which of the paths marked on the map would you choose if you did not want to climb up or down hills? A path AC path C B path BD path D

4 3. Lines that connect points of equal elevation on topographic maps are called A index contours. B contour intervals. C contour lines. D relief.

5 Use the map to answer question Which point on the topographic map has the lowest elevation? A point AC point C B point BD point D

6 5. Which of the following definitions best describes a mineral? A a substance that cannot be separated or broken down into simpler substances by chemical means B a substance made up of atoms of two or more different elements joined by chemical bonds C a naturally formed, inorganic solid that has a definite crystalline structure D a solid whose atoms, ions, or molecules are arranged in a definite pattern

7 6. Which of the following substances is a mineral? A coal, which forms from the remains of living things B fluorite, which is a crystalline solid with the chemical formula CaF2 C obsidian, which is a volcanic glass and is not crystalline D brass, which is a metal that is made by humans

8 Use the table to answer question On the Mohs hardness scale, which of the following minerals is harder than topaz? A apatite B talc C corundum D quartz

9 8. Which of the following is NOT a way to reduce the impact of mining? A recycling products that are made from minerals B reducing the use of minerals to make products C reclaiming land that has been disturbed by mining D inventing new things to make out of minerals

10 9. Which of the following minerals can be identified by taste? A magnetite B fluorite C calcite D halite

11 10. Minerals such as gypsum and halite form A from hot water solutions. B when a rock is altered by metamorphism. C when bodies of salt water evaporate. D from the cooling of magma that rises upward through the crust.

12 11. Why are gemstones valuable? A They can be used in concrete and to build buildings. B They are good conductors of heat and electricity. C They are beautiful and rare. D They taste good.

13 12. What is the difference between an element, a mineral, and a rock?

14 13. Igneous rock forms when A magma cools and hardens. B minerals crystallize out of water. C heat and pressure change the composition and texture of a rock. D natural cement binds rock fragments together.

15 Use the diagram to answer question Which of the following processes occurs at point C on the diagram of the rock cycle? A deposition B uplift C heat and pressure D melting and cooling

16 15. Volcanic activity on Earth’s surface most likely results in the formation of which of the following types of rock? A intrusive igneous rock B extrusive igneous rock C clastic sedimentary rock D chemical sedimentary rock

17 16. How does clastic sedimentary rock form? A Rock fragments are cemented together by a mineral such as calcite or quartz. B Dissolved minerals crystallize out of solution in water to form solid minerals. C Heat and pressure turn partially decomposed plant material into rock. D Skeletons of sea animals that collected on the ocean floor are cemented together.

18 17. Stratification occurs as the result of which of the following processes? A the cooling and solidification of magma B the partial or complete melting of rock C the deformation of rock by heat and pressure D the deposition of sediments in a body of water

19 18. Which of the four rock samples in the table most likely formed in the process of regional metamorphism? A Sample A B Sample B C Sample C D Sample D

20 19. Buried rock is exposed at Earth’s surface by the combination of which two processes? A weathering and deposition B uplift and erosion C erosion and deposition D deposition and uplift

21 20. Which of the following processes forms sediment? A deposition B weathering C erosion D compaction and cementation

22 21.Rock in which the composition and texture of the rock have been changed by heat and pressure is called A felsic rock. B mafic rock. C igneous rock. D metamorphic rock.

23 22.Which of the following is one way to conserve water? A using geothermal energy B using hydroelectric energy C keeping lakes and rivers free of pollution D leaving the faucet on while brushing one’s teeth

24 23. What process releases the energy that is used in nuclear power plants to generate electrical energy? A the burning of radioactive fuel B the reaction of hydrogen and oxygen to form water C the splitting of radioactive nuclei into two or more smaller nuclei D the joining of two or more nuclei to form a larger nucleus

25 24.. Astronomers usually measure the distance from Earth to the Moon in A. meters. B. kilometers. C. light-years. D. fathoms.

26 25. If you could look at the deep ocean floor, which is the best description of what you would see? A. high mountains and deep valleys B. flat, silt-covered, lifeless regions C. coral reefs with many varieties of life D. ocean ridges with active volcanoes
