Coastal Landforms

Waves dropping sand on the beach

• Weathering 
• Erosion
• Deposition

What is Deposition?

• When waves lose energy and leave sediments / sand along a coast.
• The wearing away of land, removal of beach rocks/sand by water or wind.
• An area of land that smells different to other places.
• An area that has a lot of wind.

Which of these coastal landforms are created by deposition?

• Cave
• Stack
• Beach
• Wave cut platform

What is the erosional process in which rocks are pushed by waves up against the headland, eroding the cliff face further?

• Hydraulic action.
• Abrasion.
• Attrition.
• Solution.

What is swash?

• Water that runs back into the ocean.
• Water that falls forward and moves up the shore.
• Tug of war between the drag of the wind and pull of gravity.
• Swirling of water in an area.

The movement of material along a coast by waves that approach at an angle to the shore but recede straight down the beach is called...

• Longshore drift
• Swash
• Backwash
• Recession

Which of these coastal landforms is created by erosion?

• Cave
• Tombolo
• Beach
• Spit

What is the first stage of a stack forming from a head land?

• Cracks erode to form a cave.
• Hydraulic action creates small cracks in the headland/cliff face.
• The cave becomes wider and deeper.
• The waves cut through the cave and form an arch.

What is the most advanced stage of erosion of a headland?

• Cracks erode further to create a cave.
• The roof of an arch becomes too heavy and collapses.
  
• The cave becomes wider and deeper.
• The waves cut through the cave and form an arch.

Hydraulic action is when air becomes trapped in joints and cracks on a cliff face and then a wave breaks, the trapped air is compressed which weakens the cliff and causes erosion.
