S: Seasons of Change
1: By: Jalen Prince & Quincy Jones | Ms. Turner 1st Period
2: Sedimentary Rock | How it is formed? The sun, wind, rain, cold, ice & rivers around the clock to erode the earths surface. The rocks expand under heat of the sun which cause the rocks to break down. | How it can be transformed? Heat & Pressure | Example: Sandstone
4: Igneous Rock | How it is formed? Underground or Above when the melted rock called magma, deep within the earth becomes trapped as magma cools becomes igneous. | How it can be transformed? changing temp and pressure and erosion,deposition, and cementatation | Examples: Andesite, Basalt lava, Dacite lava, Pumice, and Obsidian.
6: Metamorphic Rock | How it is formed? Rocks that were morphed were once igneous or sed. The rocks are under tons & tons of pressure, which fosters heat build up, & this cause them to change. | How it can be transformed? By pressure from sitting under other rocks or depends on the environment. | Examples: Quartise, Marble, Slate, & Gneiss.
8: Silicate Minerals | characteristics? are transparent to translucent have much luster, hard and are insoluble or nearly in acids | chemical comp? they are composed of silicon and oxygen, with addiction of ions for example aluminum,magnesium,iron and calcium
9: Nonsilicates | characteristics? vary in there in a physical appereance, some come in all colors and shapes and sizes. or forms of crystals | chemical comp? are minerals that do not include the silicon oxygen units characteristics of silicates. they contain oxygen but but not as a combination with oxygen
