Rocks from Space
Some rocks are not from Earth at all, but from way out in space. Large space rocks that orbit around the Sun are called asteroids. Smaller rocks that orbit around the Sun are called meteoroids. If an asteroid or meteoroid travels through the Earth’s atmosphere and lands on Earth’s surface it is called a meteorite. When they land they can create large hollow areas in the ground calledcraters.
Meteorites land on Earth all the time. Did you know around 500 meteorites bigger than footballs hit Earth each year? The good thing is most of them fall into the ocean. Smaller ones the size of pebbles tend to fall on land.
Minerals are natural occurring solids (that means people did not make them). They are also inorganic, which means they do not come from plants or animals. Minerals can be found cemented together inside rocks. The internal structure of a mineral follows a well organized pattern. Common examples of minerals are quartz and diamond, they have very perfect patterns.
If a rock has metal inside it is called an ore. The metal can be in flakes or contained in the minerals of the rocks. If an ore is heated the metal will pour out as a liquid, and if left to cool will harden. Examples of metals found in rocks are gold, silver, aluminium, iron and copper. Gold and silverare used to make jewellery, aluminium to make cans and foil, iron can be used to make saucepans and copper is used in electrical wires. We use metal every day.
