Composite lava are highly viscous with a high melting point. They are light colored and have low density, and have a high percentage of silica.

This shallow submerged extension … Read more

The theory of plate tectonics proposes that the earth’s lithosphere is divided into seven major and several minor plates. The movement of the plates results in the building up of stresses within the plates and the continental rocks above, which leads to folding, faulting and volcanic activity. The major plates are surrounded by fold mountains, … Read more

It is a deflecting force experienced due to rotation of earth. Because of Coriolis the air appears to turn towards its right in the northern hemisphere and towards its left in the southern hemisphere. The coriolis always acts in the perpendicular direction of the motion ofair. It is zero at the equator and increases towards … Read more
