The Solar system planet consists of the Sun and the various objects that orbit around it, all bound together by the force of gravity. It formed about 4.6 billion years ago when a dense region of molecular clouds collapsed to form the Sun and a protoplanetary disk. The...

Sediments are materials formed due to mechanical or chemical activity by the agents of denudation on preexisting rocks. They are deposited in a stratified fashion, layer after layer, at the surface of the lithosphere. Lithification of the sediments at relatively low...

Causes of Volcanism: When volcanoes erupt, the mantle’s temperature reaches about half its melting point, causing its viscosity to drop significantly. This large-scale melting rapidly decreases viscosity, allowing the material to move more quickly and increasing...
