Rock and mineral collecting is a fascinating hobby which can be shared by
entire family. Before you get started with your new hobby it is important to understand something about minerals.Rocks are made up of one mineral, or a mixture of minerals. Minerals are made up of elements, which are simple substances which cannot be broken down into any other substance. Sometimes minerals are made of only one element, but most minerals are made up of two or more elements. Many minerals are made up of a large number of elements.
Minerals are often found as shapeless lumps. These pieces are called "massive". Some minerals can also form special shapes, which can help you to identify them.
The mineral is said to "grow" when
elements that
mineral is made of gets built up in layers on
mineral's outside surface. Minerals grow into all kinds of rough shapes in
spaces between other minerals around them. If a mineral can grow freely, such as on
sea bed, or in
hole of a rock, it may form beautiful crystals.
