Hey, I was just looking for some help, if you or anyone could help me review over this draft of my assignment. I've put a lot of time into it. I would really someone to pre-review before submitting it. Thank you so much.

Week 8: Homework for Chapters 20, 21, 22 # 1: what does inorganic mean in the definition of a mineral? Inorganic means that it is not made up of another living thing or previously living thing. For example, coal is a naturally occurring mineral. # 2: name the three major types of rocks and describe how that type of rocks form a) Metamorphic rocks: form when rocks are altered by heat. b) Igneous rocks: are formed when magma hardens. C) Sedimentary rocks: form when sediments are compacted together to become one. # 3: In Earth's interior, does temperature increase or decrease with depth? As the depth increases temperature increases. # 4: Increase in and causes metamorphism Temperature; Pressure # 5: how is foliation different from sedimentary layering? If you need help, this is discussed in the lecture. -Foliation is metamorphism -Sediment layering is deposition # 6: can S-waves travel through liquids? Because liquids cannot be sheared in the way a solid can, S-waves do not travel through liquids such as the outer core. # 7: How does your answer to the previous question tell us that Earth's outer core is liquid? A shadow zone exists where S-waves do not arrive on the side of Earth opposite the focus of an earthquake. # 8: how does the rock composition (igneous rock types) of the continental crust differ from the oceanic crust? The oceanic crust is thinner and denser, and is similar in composition to basait (Si, 0, Ca, Mg, and Fe). The continental crust is thicker and less dense, and is similar to granite in composition (Si, 0, Al, K, and Na). #9: why does continental crust stand higher on the mantle than oceanic crust? Because continental crust is THICKER and LESS DENSE than oceanic crust. # 10: At which type of plate boundary do the deepest parts of the ocean occur? Convergent plate boundary #11 : Are folded rocks primarily the result of compressional or tensional forces? Compressional forces. #12: what happens to rock when stress exceeds a rock's elastic limit? The rock breaks #13: why are the most ancient rocks found on the continents, not on the ocean floor? The seaoor is not permanent. It is constamly being renewed. #14: Why are most earthquakes generated near plate boundaries? Because the plates are always in motion. The movement causes earthquakes, volcanic activity, and the deformation of large masses of rock that create mountains # 15: Describe how do stalactites and stalagmites form? Both are pointy formations found in limestone caves: One points up, the other points down. Stalact'rte points from the ceiling and stalagmites points up from the ground. # 16: describe three ways that flowing water erodes a stream channel. a) chemically b) Hydraulically c) Abrasion #17: a} List a few geologic land features that are formed from glacial deposits: Flord, cirque, horn, arete, glacial lake, u-shaped valley, moraine, kettle lake, drumline. b) Pick one and describe how the glacier creates that feature. Flords were created when the glaciers melted at the end of the Pleistocene # 18: a stream becomes a river as it moves down-gradient. Give the sequence in which the following appear in the evolution of a stream: a) meandering pattern 2nd b) rapids 1st c) delta 3rd # 19: evaporation moves water from Earth's surface to the atmosphere. Why isn't the water that evaporates from over the oceans salty? Fresh water evaporates and leaves the salt water behind. # 2|]: removal of groundwater can cause subsidence. a) If removal of groundwater is stopped, is the land likely to rise again to its original level? No b) Defend your answer. They heavy weight of the crust will not be lifted back up. Instead, water will fill in that area and create surface water features: lakes, ponds, etc
