It is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. It is characterised by convective activity which generates often vigorous thunderstorms over large areas. It is most active over continental land masses by day and relatively less active … Read more

It is the lower most layer of atmosphere. It extends up to 18km at equator, 13 km at midlatitude and about 8km at poles.It contains approximately 90% of the total mass of the atmosphere.The entire weather phenomenon takes place in this layer. It contains all the watervapour, dust particles, clouds etc. In troposphere the temperature … 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

All of the phases of water—solid, liquid and vapor—relate to glacier dynamics. Water has unique qualities that come into play in understanding the roles glaciers play in the Earth system. For example, water expands rapidly when it freezes—an increase of about 9% by volume. Also, water enters the atmosphere through the familiar cycle of melting … Read more
