Rocks are an essential part of our planet's geology, each with its unique characteristics and formation processes. From igneous rocks forged deep within the Earth to sedimentary rocks …Sedimentary Rocks. Sedimentary rocks (layered rocks) are made by the deposition of particles carried in air or water and by the precipitation of chemicals dissolved in water. These particles and chemicals come from the weathering (breaking apart in place) and erosion (carrying away and breaking apart while moving) of rocks on the Earth's surface.Overheads shown in Lab. SEDIMENTARY ROCK: Made from sediments consolidated at the earth's surface. The sediments are deposited at the earth's surface by water, wind, glacial ice, or bio-chemical processes. Typically the sediments are deposited in layers under COOL conditions [thereby distinguishing it from a layered volcanic rock …Metamorphic rocks are those that have been changed over time due to different chemical surroundings, heat and pressure. Procedure Background Information. As necessary, supplement students' understanding of basic rock/mineral testing, rock identification, and rock classification (sedimentary, igneous, metamorphic).Rock Identification Name _____ teachearthscience.org 4 II. The Identification of Sedimentary Rocks The two types of sediment that are produced by weathering are the basis for classifying sedimentary rocks into two categories: 1. Detritral sedimentary rocks are made from solid particles derived from outside the carbonate rock many colors (red, gray, green-gray, black), sedimentary structures common (ripple marks, mud cracks, fossils) Siltstone (1/16 to 1/256 mm particles) Claystone (<1/256 mm particles) Shale = ˚ssile mudstone (splits easily) H = 3 - easily scratched with a steel nail, reacts readily with HCl , rhombic cleavage Micrite Travertine

Some rocks are made of the shells of once-living animals, or of compressed pieces of plants. A good way to think about it is if a chocolate chip cookie was a rock, then the flour, sugar, butter, and chocolate chips are the minerals that make up that rock! Rocks are divided into three categories: igneous, sedimentary, and metamorphic. Read MoreSedimentary Rocks.

Rocks can be a mixture of different kinds of minerals, a mixture of many grains of the same kind of mineral, or a mixture of different grains of rocks. When you split a rock into very small pieces, the pieces are different from each other. The identification of sedimentary rocks is more than applying names, since each name is a loaded term that conveys information regarding its history, where it was formed, potentially when it was formed, and the processes that lead to its formation.

They are usually readily discernable from igneous and metamorphic rocks by the presence of grains, layers, and/or fossils. You can find my post dedicated to sedimentary rock identification here.Igneous Rocks. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. This melted rock is called magma when it is inside the earth. When magma finds its way to the surface through cracks or volcanoes, it is called lava.When lava cools on top of the earth’s surface, it forms extrusive, or volcanic, …1. Classify igneous rocks into two main types: intrusive or extrusive. Each of these types of rocks will have specific properties that will help you distinguish which type your igneous rock is. Magma is molten rock that flows beneath the earth's surface. Igneous rocks are formed by cooling magma.
