It is a kind of irrigation method which saves water and fertilizer by allowing water to drip slowly to the roots of the plants, either onto the soil surface or directly onto the root zones, through a network of valves, pipes , emitters etc. It is done through narrow tubes that deliver water directly to … 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 of air. It is zero at the equator and increases … Read more

It involves applying irrigation water which is similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. The pump supply system, sprinklers and operating conditions must be … Read more

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

: Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”   Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to … Read more

The population structure associated with a DD is a natural stage of the demographic transition, which is when countries change from having high birth and death rates to having low birth and death rates. The first stage of the transition is typically a fall in child mortality due to improvements in healthcare, nutrition and overall … Read more

Trade winds: It is the wind blowing steadily towards the equator from the north-east in the northern hemisphere or the south-east in the southern hemisphere, especially at sea. Two belts of trade winds encircle the earth. These winds are called trade winds because of the fact that they helped the sea merchants in sailing their … Read more

According to ICAR Indian soils are classified as:- Alluvial soils:-Alluvial soils are formed mainly due to silt deposited by Indo Gangetic Brahmaputra rivers. In coastal regions some alluvial deposits are formed due to wave action. Black soils:-The black soils are found mainly on the Deccan lava region covering large parts of Maharashtra, some parts 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
