Do we really need rocks?
Rocks and minerals are all around us! They help us to develop new technologies and are used in our everyday lives. Our use of rocks and minerals includes as building material, cosmetics, cars, roads, and appliances.

Eating rocks can be good for you, but only the right ones! All these elements come from minerals in rocks so, with every mouthful of cereal, we are eating rocks as part of our daily diet.
How do you tell what type of rock a rock is?
Look for crystals in igneous rocks. Examples of igneous rocks are gabbro, granite, pumice and obsidian. Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands.
Do humans eat minerals?
Most of the minerals in a human diet come from eating plants and animals or from drinking water. As a group, minerals are one of the four groups of essential nutrients, the others of which are vitamins, essential fatty acids, and essential amino acids.
Why do I feel like eating rocks?

What are the types of rock?
Part of Hall of Planet Earth. There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
What are the products of rocks and their uses?
LIMESTONE: A sedimentary rock, it is used mainly in the manufacture of Portland cement, the production of lime, manufacture of paper, petrochemicals, insecticides, linoleum, fiberglass, glass, carpet backing and as the coating on many types of chewing gum.

What kind of rock is black and shiny?
Environment: Gabbro is formed by magma that cools very slowly into hard rock below or within the Earth’s crust. Distinguishing Characteristics: dark grey-black, shiny surfaces of feldspar are visible.
What is the most common rock type?
Sedimentary rocksSedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks.
Where to take a rock to find out what it is?
Possibilities include:Your state geological survey.A natural science museum.A college or university with a geology department.A rockshop.Members of a local Gem & Mineral club or Rockhunting club (many hobbyists are experts at identification)Vendors at a Gem & Mineral show.
