Q:

Where does mica come from?

A:

Mica is a metamorphic mineral that comes from volcanoes and hydrothermal vents. It is easily recognized by its thin crystal layers that peel off in sheets. Mica is very shiny and is responsible for the glittery effect in composite rocks such as granite, gneiss and slate.

Mica is composed of silicon and oxygen. Biotite, muscovite and boromuscovite are three common variations. Mica is an excellent insulator and has many electrical applications. Mica is white, yellowish, green or gray, and can be found on most continents. The largest deposits are found in India, South Dakota, Russia and Brazil. In addition to its use in electronics, mica has many artistic applications.

    Where do rocks come from?

    A:

    Rocks come from magma, which is the molten material found within the earth. When magma cools, either above or below the earth's surface, it crystallizes and forms the igneous rocks that can later be changed into metamorphic or sedimentary rocks. Magma, which can be considered molten rock, is referred to as lava when it reaches the earth's surface.

    Where does tin come from?

    A:

    Today, most tin comes from southeast Asia and countries such as China, Indonesia, Peru, Brazil and Bolivia. Although tin was mined in England and the United States at one point in history, most tin is now found in the southern hemisphere, as there are no remaining substantial deposits in the northern hemisphere. Most countries in this region import tin from other countries, according to the Minerals Education Coalition.
