Today you will complete the Rocks and Minerals Webquest. Completing this webquest will help you study for Tuesday's quiz. The quiz will cover sections 2.1, 2.3, 3.1, 3.2, 3.3, and 3.4. Click here to view the webquest.
Rock Cycle 1. The three main types of rocks are igneous, metamorphic, and sedimentary rocks. 2. A sedimentary rock turns into a metamorphic rock by heat and pressure being applied to it. 3. An igneous rock turns into a metamorphic rock by heat and pressure being applied to it. 4. Metamorphic rocks change into sedimentary rocks by weathering and erosion grinding it down, then compaction and cementation taking place to the weathered metamorphic rock. 5. Igneous rocks change into sedimentary rocks by the same process of a metamorphic rock changing into a sedimentary rock. 6. There isn’t a beginning or an end to the rock cycle. It is called a cycle because it continuously goes through the cycle without an end or a beginning.
Volcanoes 7. When a volcanic eruption takes place; igneous, sedimentary, and metamorphic rocks are formed.
Igneous Rocks 8. Intrusive igneous rocks are formed underground, by magma. 9. Extrusive igneous rocks are formed above ground, by lava.
Mystery Rocks 10. The rocks in the photo were formed by collecting sedimentary and then compaction and cementation taking place.
Mohs Scale 11. Mohs scale is used to find the hardness of a mineral. 12. A diamond is the mineral representing the hardness level of ten. 13. Quartz is one of the most common minerals on Earth. The common shapes of quartz have an intricate design of a six-sided prism ending in a six-sided pyramid. 14. A mineral that can scratch a penny has a value of at least 3.5 on the Mohs Scale.
Streak 15. Specular Hematite shows the greatest difference of streak color and color of the mineral.
Density 16. The formula for density is Density = Mass/Volume 17. The first box has a greater density.
Pumice 18. Pumice is an extrusive igneous rock. 19. You can make pumice with a quarter cup of water, one and a half cups of sugar, a quarter cup of light corn syrup, a table spoon of baking soda, a pan, and something to stir it with. 20. You can use pumice for soap, decoration, food, jewelry, and concrete.
