  3. 3. The area drained by the river and its tributaries is called the river basin
  4. 4. The erosional work of a river results in the widening and deepening of the river valley . Such a valley is called V-Shaped Valley
  5. 5. When the water of the river falls almost vertically down a steep valley side, waterfall is formed
  6. 6. The river twists and turns to form large bends or loops . These are called as meanders
  7. 7. The circular loop that is left behind, completely cut-off from the main channel , forms an ox-bow lake
  8. 8. The fine alluvial soil brought by the river is deposited on the valley floor . This fertile part is called as flood plain
  9. 9. Long ridges of low height are formed along the banks. These are called natural levees
  10. 10. When the main channel of the river is divided into many channels. These are called as distributaries
  11. 11. A triangular shaped land that is formed due to deposition of sediments a the mouth of the river is called as delta
  12. 12. When the sea waves strike or dash against the rocks sea caves are formed
  13. 13. The through passage created by the headland due to sea waves is called as sea arch
  14. 14. The erosion of the sea arch the pillars of rocks are left standing in the open water these are called sea stacks

  19. 19. Some rocks rub against the sides of the valley floor forms an U-Shaped valley
  20. 20. The river of snow and ice, which moves very slowly is called glacier
  21. 21. When water is collected in depression tarn is formed
  22. 22. When the rock materials are deposited on the sides and floor of the valley glacier moraines are formed
  23. 23. When the lower part of the rock is eroded it forms mushroom rocks
  24. 24. The deposition of fine dust particles in large areas is called loess
  25. 25. The hills of sand in a desert is called as sand dunes
  26. 26. THE EXCESS LOAD OF ALLUVIAL IS BROUGHT BY RIVERS ARE DEPOSITED AS SANDBARS
