Transportation, depostion and erosion

• What is Traction?

  The Big boulders pushed by the power of the water
• What is saltation?

  The pebbles sized particles bounced along the river bed by the force of water
• What is suspension?

  Th small particles carried along by the river
• What is solution?

  The dissolving of rock in water
• What is deposition?

  When material is dropped
• Why does the river drop this material?

  The river looses energy and velocity
• Why does the river slow down?

  .Volume of water falls.

  .The eroded material increases.

  .Shall water.

  .Reaches the mouth.
• What is the formation of Interlocking spurs?

  • In the Upper Course, erosion happens vertically down wards.
  • The river cuts down into the valley
  • Area of hard rock is harder to erode so it creates a bend.
  • This creates interlocking spurs that look like a zip
• How is the meander formed?

  • Erosion happens on the outside bends when the power of the water is stronger.
  • Deposition happens on the inside bends when the velocity of the water slows down. (creates a slip-slope)
  • This creates bends in the river called meanders.
• how is an oxbow lake formed?

  • The erosion on the outside bends erodes more quicker, until the neck is left behind.
  • The river breaks through the land.
  • Deposition cuts off-forming the ox-bow lake.
• What type of process does an oxbow lake and meander go through?

  Depositional and Erosional
• How is a flood plain formed?

  • Erosion removes interlocking spurs creating a wide flat area.
  • Material is carried and deposited by the river
  • The height of the flood plain increases as material is deposited.
• How are leeves formed?

  • Leaves happen in the lower course along the edges of the river channel
  • During the flood, eroded materials are deposited across the floodplain
  • Heavy material is deposited close the the channel
  • Deposited materials builds up forming leeves
• How is an estuary formed?

  • Found at the mouth of the river.
  • The land is close to sea level.
  • When the tide is at its highest point, the water slows down meaning more sediment is deposited.
  • over time, mud build up creating mudflats.
• What process does the estuary go through?

  Depositional
• What process does flood plain go through?

  depositional and erosion
• what process does a leeves go through?

  depositional
• Leeves are formed when large quantities of sediment are deposited close to the river banks raising the ground.
• Estuaries is when salt and fresh water are mixed together
• What is an advantage of estuaries?

  It provides a habitat for wildlife
• What industries benefit from estuaries?

  Fishing and shipping industries
• What are floodplains?

  Floodplains are a flat area where sea levels rise
