· sedimentary rock. noun. rock formed from fragments of other rocks or the remains of plants or animals. uplift. noun. elevation of the Earth's surface due to tectonic or other natural activity. Metamorphic rocks start as one type of rock and—with pressure, heat, and time—gradually change into a new type of rock.

Synthesis. In this module we took a closer look at minerals. Minerals are very complex, and they form in a variety of ways and in a variety of settings. We examined some of the ways the mineralogist identifies minerals; some of the methods were very simple while others were a bit more complex (some of these include cleavage and reaction to acid).

Sedimentary rocks contain information about what was occurring on earth’s surface at the place and time the sediments were deposited. In some cases sedimentary rocks contain fossils, which provide information about what was living at a certain place and time on earth. There are two main groups of sedimentary rocks: chemical and clastic.

Basalt is a dark-colored, dense rock composed primarily of plagioclase feldspar and pyroxene. It is the most common rock type found in oceanic crust and is an important component of the Earth’s continental crust. Basalt is formed through the rapid cooling and solidification of magma at Earth’s surface, resulting in the formation of lava

Rocks are composed of minerals. A mineral is a naturally occurring substance which is usually solid, crystalline, stable at room temperature and inorganic. There are almost 5000 known mineral species, yet the vast majority of rocks are formed from combinations of a few common minerals, referred to as “rock-forming minerals”.

The rock cycle describes how rocks on Earth form and change over time. When rocks are pushed deep below Earth’s surface, they can melt to form magma. Magma that reaches Earth’s surface through volcanic activity is called lava. Igneous rocks form when magma or lava cools and solidifies. Weathering breaks igneous and other types of rocks into
