Some air movements are the result of the systematic pressure gradients that arise from latitudinal changes in the Earth’s surface temperature. One notable example is the Hadley Cell, a movement of warm air from the tropics that rises, flows toward the poles and then cools and sinks at around 30 degrees north and south of … 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

Earth magnetism is the property of earth behaving like a dynamo and showing magnetic property just like that of a magnetic bar. There are various theories behind this property. There is no valid reason for the cause of earth’s magnetism or why earth has giant magnetic field but there are some theory related to earth’s … Read more

Overpopulation With increasing population, demands of the country increase which further results in depletion of resources.     Over-consumption and waste As the standards of living of people improves, they tend to consume more and waste even more. Deforestation and the destruction of ecosystems Forests are cut annually, to make space for multiplexes, residential complexes … Read more

Grasslands are known by variousnames in different parts of the world.Grasslands are found in areas having well defined hot and … Read more

The continental drift hypothesis was developed in the early part of the 20th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move. Alfred Wegener proposed that … Read more

Surface Irrigation In this method water flows and spreads over the surface of the land. Varied quantities of water are allowed on the fields at different times. Hence, flow of water under surface irrigation comes under unsteady flow. As a result it is very difficult to understand the hydraulics of surface irrigation. However, suitable and … Read more

There are several reasons for this. First, the mountain topography in Karnataka is broader than the narrow topography of the Ghats in Maharashtra. Due to the greater width of the mountains, the rain bearing winds have to necessarily travel a longer distance and have more time for the drops to coalesce and precipitate as rainfall, … Read more

On 12 August 2018, after 20 years of talks, the leaders of the five littoral states to the Caspian Sea – Azerbaijan, Iran, Kazakhstan, Russia and Turkmenistan – finally signed a treaty defining its legal status. The ‘Convention on the Legal Status of the Caspian Sea’ has not resolved all the long-standing issues; in fact, … Read more
