Climate is a major sculptor of landforms. One of generous precipitation often induces extensive erosion through plentiful runoff and stream flow. A moist, cool climate can even favor the formation of glaciers in mountains and high latitudes. Given the proper conditions, these massive ice bodies advance and heavily impact the terrain. A whole slew of … Read more

Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth’s surface, and has a radius of about 3,485 kilometers (2,165 miles). Planet Earth is older than the core. When … Read more

Main causes of the earthquake are plate tectonics, volcaniceruption or anthropogenic activities like explosions, reservoir induced seismicity etc. There is arelease of huge amount of energy in the form of sound and seismic waves causing shaking of earth’s surface. The regions which are on the  boundaries of the tectonic plates are more prone to earthquake.  … Read more

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

In Fissure volcanic eruptions, the Lava comes out to the surface through the cracks of the rock strata and hence the fissure eruptions are not much explosive. The fissure eruptions are smooth and the Lava spreads to a larger area, so they form landscapes such as plateaus.  The major component of volcano are basalt. Basalt is … Read more
