GED® Science: The Rock Cycle & Minerals (Deep Dive)

A deep dive into the rocks beneath your feet, expanding the single 'Rock Cycle & Minerals' lesson from the GED® Earth & Space Science course into a full mini-course. You'll start with minerals -- the building blocks of rocks -- and how to identify them, then explore how each of the three rock families forms: igneous from cooling magma, sedimentary from layers of sediment, and metamorphic from heat and pressure. Finally you'll see how the rock cycle ties them all together, with any rock able to become any other over time. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations.
