MAJOR LANDFORMS MAJOR LANDFORMS Presentation Transcript

  • The place where a river originates is the called a source of a river
  • A place where river joins another water body is called mouth of a river
  • The area drained by the river and its tributaries is called the river basin
  • The erosional work of a river results in the widening and deepening of the river valley . Such a valley is called V-Shaped Valley
  • When the water of the river falls almost vertically down a steep valley side, waterfall is formed
  • The river twists and turns to form large bends or loops . These are called as meanders
  • The circular loop that is left behind, completely cut-off from the main channel , forms an ox-bow lake
  • The fine alluvial soil brought by the river is deposited on the valley floor . This fertile part is called as flood plain
  • Long ridges of low height are formed along the banks. These are called natural levees
  • When the main channel of the river is divided into many channels. These are called as distributaries
  • A triangular shaped land that is formed due to deposition of sediments a the mouth of the river is called as delta
  • When the sea waves strike or dash against the rocks sea caves are formed
  • The through passage created by the headland due to sea waves is called as sea arch
  • The erosion of the sea arch the pillars of rocks are left standing in the open water these are called sea stacks
  • A steep vertically wall facing the sea is called sea cliff
  • Beaches are formed by the deposition of sand, gravel and pebbles on the sea shore
  • Lagoons are formed when sea water is enclosed between the coast and sandbars
  • The boundary of the snow fields is called snowline
  • Some rocks rub against the sides of the valley floor forms an U-Shaped valley
  • The river of snow and ice, which moves very slowly is called glacier
  • When water is collected in depression tarn is formed
  • When the rock materials are deposited on the sides and floor of the valley glacier moraines are formed
  • When the lower part of the rock is eroded it forms mushroom rocks
  • The deposition of fine dust particles in large areas is called loess
  • The hills of sand in a desert is called as sand dunes
  • THE EXCESS LOAD OF ALLUVIAL IS BROUGHT BY RIVERS ARE DEPOSITED AS SANDBARS
  • When the broken rock materials are deposited on the near the coast, sandbars are formed
