2021-6-18 Rocks are generally made up of two of more minerals, mixed up through geological processes. For example granite is an igneous rock mostly made from different proportions of the minerals quartz, feldspar and mica as interlocked crystals; a sandstone is a sedimentary rock that can also contain quartz, feldspar and mica,

Rocks can be made of minerals or crystals but cannot typically be formed by a single mineral except in monomineralic rocks, which are almost unheard of in the natural world. Rocks can contain crystalline minerals, but typically also contain other solid-state molecular structures as well.

2021-2-8 WHAT ARE ROCKS MINERALS? A mineral is a natural solid with a characteristic crystal shape. Mineral crystals can form when hot water containing dissolved minerals cools down and forms a solid. Rocks on the other hand are made of mineral pieces mixed together. Rocks are made through the rock cycle! Read more about it below. To better understand ...

2005-5-8 Minerals can be identified in rocks by a variety of features described in the Minerals section of the chapter, including crystal form, cleavage, hardness, color, and luster. Rocks are classified into three distinct groups - igneous, sedimentary, and metamorphic - and each is discussed in a separate section. Each rock group is further subdivided ...

2017-3-29 Metals from rocks. Some metals are held inside rocks as minerals. The rock or mineral that holds the metal is called an ore. An ore is heated with chemicals until it melts and the pure metal separates out as a liquid. The liquid then cools and hardens. A few metals, such as gold, silver, and copper can be found in pure form as metal elements ...
