Video Distribution of Oceans and Continents. ABRAHAM ORTELIUS a Duchy map maker 1596 first proposed the possibility of joining the continents such as America with Europe and Africa ANTONIO PELLEGRINI drew the map showing the three continents together.
Video This chapter deals with Geomorphic process, exogenic, endogenic processes, diastrophism, volcanism, weathering, types of weathering mechnical(unloading, expansion, temperature change expansion freezing thawing frost wedging salt weathering ), chemical (solution, carnonation, hydration oxidation and reduction),biological (plants, animals man).biological activity and weathering, special effects of weathering, significance of weathering, mass movement, slow movement, rapid movementland slide, erosion , deposition, soilformtion, process of soil formation soil forming factors, parent material, topography, climate, biological activity, time.
Video Landforms and Their Evolution. After weathering, geomorphic agents operate the landforms to change. Land form: small to medium reacts or parcels of the earth’s surface are called landforms. Several landforms together are called landscape Each landform has its own shape, size and materials Geomorphological processes are slow but significant in long run
Video Composition and Structure of Atmosphere. Air is essential to the survival of all organisms. Some organisms like humans may survive for some time without food and water but can’t survive even a few minutes without breathing air. That shows the reason why we should understand the atmosphere in greater detail.
Video Solar Radiation, Heat Balance And Temperature. Solar radiation, variability of insolation at the surface of the earth heating and cooling of atmosphere, terrestrial radiation, heat budget of the planet earth, latitudinal variation in net radiation balance, temperature, factors influencing the temperature (such as the latitude, altitude, distance from the sea air mass ocean currents) distribution of temperature, isotherm.
Video Atmospheric Circulation And Weather Systems. Atmospheric pressure, vertical variation pressure, horizontal distribution of pressure, world distribution of sea level pressure, factors affecting the velocity and direction of wind( pressure gradient force, frictional force, carioles force, pressure and wind, ) general circulation of the atmosphere, ENSO seasonal wind, local winds land and sea breezes mountain and valley winds, air masses , fronts, exratropical cyclone tropical cyclones, thunderstorms, tornadoes.
Video This chapter deals with Humidity, types of humidity, relative humidity, absolute humidity, specific humidity, dew point, condensation, saturated air, types of precipitation -dew, frost, fog, mist, clouds cirrus, cumulus, stratus, nimbus, precipitation, types-(rainfall, sleet, snowfall, hailstones,)rainfall types convectional type, orographic rainfall, cyclonic rainfall, world distribution of rainfall.
Video World Climate and Climate Change. The world climate can be studied by organizing information and data on climate and synthesizing them in smaller units for easy understanding, description and analysis. Three broad approaches have been adopted for classifying climate. They are empirical, genetic and applied. Empirical classification is based on observed data, particularly on temperature and precipitation. Genetic classification attempts to organize climates according to their causes. Applied classification is for specific purpose.
Video Water (Oceans). The earth, fortunately has an abundant supply of water on its surface. Hence, our planet is called the ‘Blue Planet’. HYDROLOGICAL CYCLE The hydrological cycle, is the circulation of water within the earth’s hydrosphere in different forms i.e. the liquid, solid and the gaseous phases. It also refers to the continuous exchange of water between the oceans,
Video Movements of Ocean Water.The ocean water is dynamic. Its physical characteristics like temperature, salinity, density and the external forces like of the sun, moon and the winds influence the movement of ocean water. The horizontal and vertical motions are common in ocean water bodies. The horizontal motion refers to the ocean currents and waves. The vertical motion refers to tides.
Video Life on the Earth. Living organisms of the earth, constituting the biosphere, interact with other environmental realms. The biosphere includes all the living components of the earth. It consists of all plants and animals, including all the micro- organisms that live on the planet earth and their interactions with the surrounding environment.
Video India - Location. India with its area of 3.28 million sq. km accounts for 2.4 per cent of the world’s land surface area and stands as the seventh largest country in the world.
Video of Geography subject CBSE class 11 Geography. Structure and Physiography. Structure and Relief; physiographic divisions Drainage systems: concept of water sheds — the Himalayan and the Peninsular
Video Drainage System. The flow of water through well-defined channels is known as ‘drainage’ The network of such channels is called a ‘drainage system’. The drainage pattern of an area is the outcome of the geological time period, nature and structure of rocks, topography, slope, amount of water flowing and the periodicity of the flow.
Video Climate Weather and climate - spatial and temporal distribution of temperature, pressure, winds and rainfall; Indian monsoons: mechanism, onset and variability - spatial and temporal; climatic types Natural vegetation - forest types and distribution; wild life conservation; biosphere reserves Soils - major types and their distribution, soil degradation and conservation
Video Natural vegetation refers to a plant community that has been left undisturbed over a long time, so as to allow its individual species to adjust themselves to climate and soil conditions as fully as possible.
Video Natural Hazards and Disasters. Disaster is an undesirable occurrence resulting from forces that are largely outside human control, strikes quickly with little or no warning, which causes or threatens serious disruption of life and property including death and injury to a large number of people, and requires therefore, mobilisation of efforts in excess of that which are normally provided by statutory emergency services
Video Introduction to Maps. The history of map making is as old as the history of itself. The oldest map was found in Mesopotamia drawn on a clay tablet that belongs to 2,500 B.C.
