Geography

• Weathering is the process of breaking down rocks, soil, and minerals through contact with the atmosphere, water, and biological organisms.
• cliff


  A big mass of rock
• headland

  land that justs out to the sea
• wave-cut platform

  the flat rocky area left behind when waves erode a cliff.
• Bay


  a smooth curve of coast between two headlands
• Cave


  A large hollow rock
• Stack


  A pillar of rock left in the sea
• Arch


  the curved structure left when the sea erodes the inside of a cave.
• beach


  an area of sand or pebbles that connects to the sea.
• salt marsh


  a low-lying marshy area by the sea
• Spit


  a strip of sand
• Hydraulic Action


  water is forced into the rock. this squashes the air inside. this air blasts out when waves retreat. this can break the rock apart.
• Abrasion


  fragments of rock are picked up and hurled at the cliff by the sea. they scrape and gouge the rock.
• Solution/ corrosion 


  chemical action of the sea water, where salts in the water can dissolve rocks.
• Attrition 


  loose sediment carried by the sea knock into each other, they break down and become smaller and more rounded
• Spring tides


  The tide after a new or full moon. this is when there is the greatest difference between high and low water.
• Neap tides


  seven days after a spring tide. this is when a period of moderate tides when the Sun and moon are right angles to each other
• Ebb tides


  This is when the seaward flow in estuaries or tidal rivers during a tidal phase of lowering water level.
• ebb

  the change from high to low
• Backwash


  the movement back into the sea
• Swash


  the movement of water as it goes up onto shore
• What are the 3 factors that determines the height of the waves?

  the fetch, the strength, the time
• what is fetch?

  the distance the wave has travelled
• which direction does 'backwash' go?

  down
• which direction does 'swash' go?

  up
• backwash is greater than swash.

• Birth rate


  The number of people being born for each 1000 of the population
• Death rate

• Natural decrease


  The difference between birth and death rate
• Population growth
