Types of Rocks and Minerals. A mineral is a naturally constructed, inorganic solid that has a specific crystalline structure. Elements are substances that cannot be separated or broken down into simpler substances by any chemical means. A compound is a substance that is made up of atoms of two or more different elements joined by chemical bonds. Crystals, as we know, are very beautiful and are ...

Igneous rocks are one type of rock. These rocks are associated with volcanoes and form at plate boundaries, either as magma under the ground hardens or as lava flows over the surface and cools. Magma cools to form intrusive igneous while lava cools to form extrusive igneous rocks. Many igneous rocks are basalt or granite, two of the most abundant rock types on the planet. Other examples of ...
