The Rock Cycle

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic …

What Is a Mineral? | Video

Minerals are inorganic, which means that they are formed by the Earth through geological processes. Minerals are not organic, which means that they are not formed by plants or animals. Here I've assembled some examples of different minerals. Note how they all have different crystal shapes, they come in different colors, and amazingly, they ...

Earth's Systems

It turns out that no single feature is more significant than the others—each one plays a vital role in the function and sustainability of Earth's system. There are five main systems, or spheres, on Earth. The first system, the geosphere, consists of the interior and surface of Earth, both of which are made up of rocks.
