FINAL REVIEW: ROCKS & MINERALS 1. Which statement is true of all rocks? (1) Rocks contain organic material. (2) Rocks contain fossils. (3) Rocks are composed of minerals. (4) Rocks are formed in layers. 4. Igneous rocks are formed by: (1) weathering (3) volcanic activity (2) cementation (4) sedimentation Natural Cement 2. Weathering and erosion of Earth’s crust are primarily caused by (1) gravity (3) evaporation (2) volcanic activity (4) sedimentation 3. The diagram below shows a rock sample and an identification key. Key This rock sample would best be classified as (1) volcanic (3) metamorphic (2) sedimentary (4) igneous Shell fragment Feldspar fragment Quartz fragment 5.

In which type of rock are fossils generally found? (1) igneous (3) sedimentary (2) metamorphic (4) volcanic 7. Dust and ash entering the atmosphere as a result of volcanic eruptions can affect Earth’s (1) tidal activity (3) weather and climate (2) rotation and revolution (4) orbital shape 8. Rocks are classified as igneous, metamorphic, or sedimentary according to: (1) their color (3) how they formed (2) their shape (4) the minerals they contain 9.

Amber Plant Sap is a substance secreted by some trees. Many years ago, plants and small animals were caught in the sap on the trees. Sap hardens and turns into a clear substance called amber. The plants or animals are preserved as fossils in the amber.

Gems & Minerals: There are about 4,000 types of minerals on Earth. Of these, only about 15 are used to make gems. Gems are minerals that may have been cut & polished to make them sparkle. The diamond is the hardest natural substance we know. Diamonds form deep underground at very high temperature & pressure conditions caused by the overlying thick layers of rock that squeeze the carbon atoms into a tight, strong crystal. Diamonds might grow under these conditions for 1 billion to 3 billion years & therefore are considered the oldest gemstone. Only about 20 percent of diamonds are made into jewels. Because they are so hard, most diamonds are used to make tools such as dental drills & metal cutters. *Base your answers to questions 42 through 44 on the information below. 42. Explain why hardness is a valuable property of some minerals. ________________________________________________________________________________________ ________________________________________________________________________________________ 43.

When diamonds are shipped to jewelry stores, they are individually wrapped in paper. Explain why the paper is needed to protect each diamond from damage. _______________________________________________________________________________________ THEY ARE USED TO MAKE TOOLS & OTHER USEFUL PRODUCTS BECAUSE OF THEIR HARDNESS.
