Most elements are formed due to fusion of simple nuclei to give heavier nuclei i.e., nucleosynthesis or nuclear fusion reactions taking place in the stars. Atoms of these elements began to fall together about six billion years ago to form a system, presently called the solar system. A part..

Rocks of the Earth - Rocks are polycrystalline solid portions of the earth's crust having a definite texture and mineral content. Usually two or more minerals combine to form different rocks. They are classified ..

Structure of the Earth - In outward appearance, the earth is a nearly spherical ball with a radius of 6350 kilometers. Internally, the earth consists of three major layers. They are: Crust Mantle Co..

During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distribution of elemen..

About AD1600, William Gilbert, who was a court physician of Queen Elizabeth of England, performed certain experiments using spherical lodestones. When he placed small, pivoted magnetic needles at different positions on this sphere, he found that their behavior was quite similar to that of magnetize..
