The Rock Cycle: the Rock Cycle in Action

Upon viewing the The Rock Cycle video series, students will be able to do the following: Explain that rocks are non-living substances made up of one or more minerals. Understand that a mineral is a natural substance with a definite crystal structure. Differentiate between the three main groups of rocks including: igneous rocks, sedimentary rocks, and metamorphic rocks. Summarize the characteristics of igneous rocks and the function of magma and lava in forming igneous rocks. Explain that some sedimentary rocks are formed from sediments or particles which are deposited, compacted, and cemented into rock. Understand that metamorphic rocks are formed from other rocks that change as a result of heat, pressure, or chemical reactions. Compare and contrast the main characteristics of each of the three main types of rocks. Generally explain the process of weathering and its role in breaking down rocks and other materials into smaller and smaller pieces. Describe erosion as the process of transporting weathered rocks, particles and sediments from one place to another. Illustrate the rock cycle, in a sketch highlighting ways that rocks change from one form to another. Understand that the rock cycle does not always circulate in one direction, but that rocks can change from one type to another depending on conditions.
