Importance of Physical geography
Physical geography is the branch of geography dealing with natural features and processes. It includes the study of lithosphere (Examples: landforms, drainage, relief and physiography), atmosphere (its composition, formation, elements and controls of weather and temperature, pressure, winds, rainfall, climatic types, etc.), hydrosphere (oceans, seas, lakes and related features with water realm) and biosphere (life forms including human being and macro-organism and their supporting mechanism, viz. food chain, ecological parameters and ecological balance). Soils are formed through the process of pedogenesis and depend upon the parent rocks, climate, biological activity, and time.
Time provides maturity to soils and facilitates in the maturity of soil shapes. Each component is significant for human beings. Landforms give the base on which human activities are placed. The plains are utilized for agriculture. Plateaus provide forests and minerals. Mountains provide pastures, forests, tourist spots and are sources of rivers providing water to lowlands. Climate influences our house types, clothing and food habits. The weather has a thoughtful consequence on vegetation, cropping pattern, domestic animals farming, and several industries, etc. Human beings have developed technologies which adjust climatic elements in a restricted space such as air conditioners and coolers. Temperature and rainfall make sure the compactness of forests and quality of grassland.
For, example, in India, monsoonal rainfall sets the cultivation measure in motion. Rainfall recharges the soil water aquifer which later provides water for agriculture and household use. We study oceans which are the storehouse of resources. Besides fish and other sea-food, oceans are rich in mineral resources. India has developed the technology for collecting manganese nodules from the oceanic bed. Soils are renewable resources, which influence a number of economic activities such as agriculture. The fertility of the soil is both naturally determined and culturally induced. Soils also make available the foundation for the biosphere accommodating plants, animals, and microorganisms.
