The word polymer comes from poly- (many) and -mer (part). A polymer may be a natural or synthetic macromolecule comprised of repeating units of a smaller molecule (monomers). While many people use the term 'polymer' and 'plastic' interchangeably, polymers are a much larger class of molecules which includes plastics, plus many other materials, such as as cellulose, amber, and natural rubber.

The processes involved in the extraction of metal from their ores and refining is called metallurgy.
The three steps of metallurgy are:
1)Concentration of ore
2)Conversion of ore into metal
3)Refining of impure metal.
Concentration of ore: The unwanted impurities such as sand, rocky material, earthy particles etc present in an ore are called gangue.
The method for removing gangue from ore depend on some differences in physical or chemical properties of ore and gangue.

Meteors: Meteors are stony or metallic bodies of very small size, traveling in interplanetary space and become visible when they travel through the earth’s surface. The meteors are also called shooting stars. Some meteors are the dust particles left behind by comets and others are pieces of asteroids which have collided. These are quite small, some may be as small as grain of sand.
Meteorite: While traveling through the earth’s atmosphere, these fast moving bodies (meteors) get heated up to a very high temperature by air friction. The heat produced is so high that the meteor starts glowing and then burnt and lost. The path of the meteor appears as a streak of light in the night sky. Very large meteors are able to survive from such heat destruction and actually reach the earth’s surface. These meteors are called meteorites.

Galaxies are collections of stars, dust and gas rotating around super massive black holes. It is believed that there are 200 million or more galaxies in the known universe. A galaxy can range in the number of stars as well as its size.
Small galaxies, such as dwarf galaxies can contain as little as tens of millions of stars, while on the other end of the scale, there are massive galaxies with hundreds of trillions of stars. The diameter of an average galaxy can reach 326,000 light years, meaning that it would take light 326,000 years to cross the average galaxy.
