GEOGRAPHY

Geography is the study of the physical features of the earth like mountains, plains, valley, plateau, hills, glaciers and its atmosphere.

Cyclones and Anti-Cyclones

Cyclones are low pressure centres by which air-currents move upwards. Winds blow, towards the lowest pressure centre. These cyclones cause stormy weather and heavy rainfall along the path. By other locations of these origin, cyclones are classified broadly into two types: Temperate and tropical. Temperate cyclones are concentrated in the center latitudes b/w 35° to(…)

Atmosphere

Atmosphere is a gaseous envelope extending many kilometers above our planet’s surface. One of many four major components of environment, the atmosphere is one of dynamic as modifications to it hap not just in one season to a new but additionally in just a short while of couple of hours. In the total mass from(…)

Major Land Forms

Endogenetic forces are responsible for development of primary land form on 1st order and second order land form like Mountain, Continent, Plateaus etc. Exogenetic forces are the destructive forces by the river, glacier, wind, wave etc. which transformed the first & second order land forms into 3rd order landform like plateau, plain etc. Types of(…)

Evolution of the Earth

Continental Drift Theory Alfred Wegner, a German Scientist, in 1912, proposed that all land masses of the world had been formed from one super-continent, called Pangaea. Pangaea had evolved some 280 million years ago, at the end of the Carboniferous Period. 150 million years ago Pangaea had split into a northern continent called ‘Laurasia’, and(…)

Types of Soils

Soils undoubtedly are a product of a complex combination of weathered and eroded rock materials on one hand and organic resides on the other instrument. Weathering changes consolidated rock for an unconsolidated (loose) material. The decomposition of plants and micro-organisms releases organic chemicals (humus) that connect to the loose material, giving rise to be able(…)

Types of Rocks

The earth’s solid layer, called lithosphere is about 100 kms in thickness. The word ‘lithosphere’ literally means ‘a sphere of rocks’.  “Rocks are made of individual solid substances called minerals. Each mineral usually contains two or more elements of which the whole earth is made.” All rocks are not hard. Clay, for example, is an(…)

Latitudes and the Longitudes

Latitudes:  Latitudes are circles separating our planet into two unequal parts and they also run parallel for the equator that cuts into two equal halves, i.e., two hemispheres. The equator is always 0 o latitude and the poles are at 90 o latitude. Count of latitude is 181. Longitudes: The longitudes are ‘great circles’ that(…)

Universe and the Big Bang Theory

The study of the universe on the grand scale is known as Cosmology. Most the theories of development of universe use the astronomical observation “Redshift”. In the event the star is moving towards the observer its light is going to be now use nowhere end in the spectrum and it’s shifted toward red end if(…)

Earth and the Solar System

The Earth is inclined on its axis at an angle of 66.5 degrees. It really is spherical in shape with compression for the poles and bulge on the equator, due to which it’s called an oblate spheroid/Geocide. The diameter of the earth for the equator is 7,927 miles including the poles it’s 7,900 miles. The(…)

Indian State of Forest Report 2011

The National Forest Policy of India, 1952 directed at bringing 1 / 3 of landmass of the united states under forest cover. Over time, efforts were meant to accomplish that goal through conservation and afforestation activities. However, competing pressures from increasing population and developmental activities generated a considerable shrinkage on this natural resources. A necessity(…)
