  • where a river meets the sea
    Mouth
  • When the water dissolves certain types of rocks, eg limestone. What type of erosion is this?
    Solution
  • a small river or stream that joins a larger river
    Tributary
  • When the river loses energy, it drops any of the material it has been carrying. This is known as __________.
    Deposition
  • When the river flows over flatter land they develop large bends called ..........
    Meanders
  • As a river goes around a bend, most of the water is pushed towards the outside. This causes increased speed and therefore increased ___________.
    Erosion
  • This is where a river begins
    Source
  • The build-up of deposited sediment on the inside bank of a river is known as a ________________ (or sometimes river beach).
    Slip off slope
  • This is the sheer power of the water as it smashes against the river banks. Air becomes trapped in the cracks of the river bank and bed, and causes the rock to break apart. What type of erosion is this?
    Hydraulic action
  • Deposition can occur to cut off a meander, leaving a horseshoe-shaped ___________.
    Oxbow lake
  • Floodplains form due to both erosion and what other process?
    Deposition
  • When pebbles grind along the river bank and bed in a sand-papering effect. What type of erosion is this?
    Abrasion
  • What is the name for an area of land which is covered in water when a river bursts its banks.
    Floodplain
  • This is the point at which two rivers meet
    Confluence
  • When rocks that the river is carrying knock against each other. They break apart to become smaller and more rounded. What type of erosion is this?
    Attrition
  • The lateral erosion on the outside bend causes undercutting of the bank to form a ___________
    River cliff
