  Leaching is removal of materials in solution or suspension downwards as water move vertically through the soil body by force of gravity. Leaching results into movements of soluble and suspended materials in water percolation. Leaching involves two forms: Elluviation - which is washing out of materials in solution or suspension from the overlying parts of the soil body; and  Illuviation - which is accumulation of materials taken from the overlying parts of the soil body.

  A forest is a collection of trees, shrubs, grasses, herbs, mosses, fungi, or a large piece of land covered by either one or more specimen of trees that grows naturally or planted whereas forestry is the science of developing, managing, and protecting existing forests, in an effort to conserve them in their original form.

  The year 2016 was the warmest year since record-keeping began in 1880. The global average surface temperature last year was 0.94°Chigher than the 20th-century average and July was the warmest month ever recorded. Two phenomena were responsible for this. One was climate change and the other was El Nino. Previously 2014 was the warmest year and the record was broken in 2015 and subsequently now in 2016 showing a continuous rise in the earth’s temperature. This is only the second time that the annual temperature record has been broken three years in a row. The previous trio was during World War II. All 16 years in our current century rank among the 17 warmest on record.

  what is hydrological cycle? within the drainage basin, there is a hydrological cycle with hydrological processes The hydrological cycle is the endless circulation of water from the ocean into the atmosphere through evaporation, back to the land in the form of rain again into the ocean in the form of surface run off in other words the hydrological cycle describes the circulation of water from hydrosphere (ocean), atmosphere and lithosphere (land) in a great series of continuous interchange of both geographical position and physical state every day about 1400000 million metre cubic of water are evaporated from the earth surfaces. 1050000 million metre cubic of water reprecipitate into the ocean and 350000 millions metre cubic of water reprecipitate on lands surfaces eventually flow back into the oceans such water movement is driven by solar energy (the heat derived by the earth from the sun) because this energy is necessary to bring about important changes in the physical state and...
