My rocks are Diorite, Gabbro, Rainbow Obsidian, Rhyolite, Basalt. Diorite is a rock that has many spots on it and is usually in a square form, and is found in Minnesota. Gabbro is a rock that has many, many spots on it, and is in a weird looking square form, and is found in New England. Rainbow Obsidian: Black is the most common color of obsidian. However, it can also be brown, tan, or green. Rarely, obsidian can be blue, red, orange or yellow. The colors are thought to be caused mainly by trace elements or inclusions, In the western US it is found at many locations in Arizona, California, Idaho, Nevada, New Mexico, Oregon, Washington, and Wyoming. Rhyolite is a rock that kind of looks like a peacock, and is round, and is found in Nevada. Basalt is a rock that looks glossy and looks dirty. It is black or sometimes white, and is found in Washington.
My rocks are, Limestone, Marble, Shale, Slate, and Schist. Limestone is a rock that you can sometimes find in your driveway, if you have a gravel driveway. It can be found in the USA. Marble is a rock that kind of looks sparkly, but it's glossy. It can be found in the USA. Shale is a dark rock that is dull and doesn't really stand out. It can be found in USA. Slate is a rock that can be many colors and is very thin and can break easily. It can be found in the USA. Schist is as rock that is a yellow/greenish color. It can be found in the USA.
My rocks are Sandstone, Brecca, Conglomerate, Shale, and Coal. Sandstone is a rock that is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Most sandstone is composed of quartz and/or feldspar because these are the most common minerals in the Earth's crust. Brecca is a clastic sedimentary rock composed mainly of sand-sized minerals or rock grains. Shale is a fine-grained, clastic sedimentary rock composed of mud that is a mix of flakes of clay minerals and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite. Coal is which has meant "mineral of fossilized carbon" since the 13th century) is a combustible black or brownish-black sedimentary rock usually occurring in rock strata in layers or veins called coal beds or coal seams.
