Different types of Soil, their Conservation Methods Soil conservation measures should aim at preventing or at least minimizing the soils loss. In order to do this proper land utilization coupled with agricul­tural practices should be adopted. Broadly categorizing there are two methods of soil conservation. These are biological and mechanical. The biological measures are again divided into Agronomic, Agrostological and Dry farming we shall study these measures in some detail. Methods 1. Agronomic practices: Normally, the land will possess a vegetational cover so as to prevent erosion. The measures to be followed must be patterned along the nature's own methods of conservation. The following are some of the methods. 2. Contour farming: Crops are cultivated along the contour of the land. The plow marks will be on level and can hold the rain. Even in heavy rain, the runoff is checked by the plants growing along the contour. Tillage: contour tilling will preve...

The term "evolution" usually refers to the biological evolution of living things. But the processes by which planets, stars, galaxies, and the universe form and change over time are also types of "evolution." In all of these cases there is change over time, although the processes involved are quite different. In the late 1920s the American astronomer Edwin Hubble made a very interesting and important discovery. Hubble made observations that he interpreted as showing that distant stars and galaxies are receding from Earth in every direction. Moreover, the velocities of recession increase in proportion with distance, a discovery that has been confirmed by numerous and repeated measurements since Hubble's time. The implication of these findings is that the universe is expanding. Hubble's hypothesis of an expanding universe leads to certain deductions. One is that the universe was more condensed at a previous time. From this deduction came the suggestion t...

Cartographers and geographers divide the Earth into  longitudes  and  latitudes  in order to locate points on the globe. Dividing Earth into Hemispheres Together, they form the Earth’s  geographical coordinates , and represent the angular distance of any location from the centre of the Earth. Both latitudes and longitudes are measured in degrees (°) and minutes (′). The Earth is (almost, but not quite) a sphere that rotates around its axis. If we draw a line passing through the centre of the Earth along its rotational axis, the line would pass through the North and the South Pole. The  Equator  is an imaginary line perpendicular to this axis. It is equidistant from the North and South poles , and divides the globe into the Northern Hemisphere and the Southern Hemisphere. Most locations on the Equator experience consistently high temperatures throughout the year. They also experience almost 12 hours of daylight every day during the y...

Agriculture:                            Agriculture and allied sectors like forestry and fisheries accounted for 13.7% of the GDP (gross domestic product) in 2013, about 50% of the workforce. The economic contribution of  agriculture  to  India's  GDP is steadily declining with the country's broad-based economic growth.

Energy Resources:                                                    Energy Resources  are the opportunities an area offers to generate electricity based on its natural conditions and circumstances. Some of these energy resources are obvious; an area might contain coal, oil, wood, or gas. But others, like renewable resources such as wind , solar, hydroelectric, and wave power are not so obvious—they're based on the natural weather patterns and features of an area.  Download PDF File,  https://drive.google.com/open?id=0B46BMwgysPj5Tm9mWjFtS1duVE0

CLIMATE: The  climate  of  India   comprises a wide range of weather conditions across a vast geographic scale and varied topography, making generalizations difficult. Based on the  Köppen system ,  India  hosts six major climatic subtypes, ranging from arid desert in the west, alpine tundra and glaciers in the north, and humid tropical regions supporting rain forests in the southwest and the island territories. Many regions have starkly different  microclimates . The nation has four seasons: winter (December, January, and February), summer (March, April, and May), a  monsoon rainy  season (June to September), and a post-monsoon period (October to November).
