  • Name the 3 types of atmospheric hazards.
    • Atmospheric
    • Geomorphological
    • Flooding
  • Name 3 things that increase the likelihood of a natural hazard occurring.
    • Urbanisation
    • Agriculture
    • Climate change
  • What are the 5 processes at destructive plate margins.
    • The plates move towards each other
    • Composite volcanoes
    • Fold mountains
    • Earthquakes
    • Convection currents
  • Define the 4 processes at constructive plate margins.
    • Move away from each other
    • Shield volcanoes
    • Earthquakes
    • Convection currents
  • Define the 2 processes at conservative plate margins.
    • Move side by side
    • Earthquakes
  • How does ridge push work?
    • Magma rises as the plates move apart
    • The magma cools to form a new plate material
    • That plate material then slides away from the ridge
    • Causes the tectonic plates to move away from each other
  • How does subduction/slab pull work?
    The denser plate sinks back into the mantle due to gravity.
  • How does a convection current work?
    • The magma rises due to the hot core and sinks back down towards the core after it has cooled.
    • Convection builds up pressure so that the plates move too
  • What do constructive plates cause?
    They move apart causing a new crust to form and causing volcanic eruptions.
  • What do destructive plates cause?
    They collide which can cause:
    • The formation of fold mountains
    • Subduction
    • Earthquakes
    • Volcanic eruptions
  • How many tectonic plates is the earth's crust made up of?

    Seven
  • Name the 2 properties of the oceanic crust.
    • Thin
    • Dense
  • Name the 2 properties of the continental crust.
    • Less dense
    • Thicker
  • Define the term abrasion.
    Caused by waves picking up material which is forced against the cliff face wearing it away.
  • Define the term attrition.
    Where stones and pebbles in the sea knock against each other causing them to become smoother and rounded.
  • Define the term fetch.
    The distance over which wind has blown to form a wave.
  • Define the term backwash.
    The movement of water back down a beach.
  • Define the term swash.
    The movement of water up a beach
  • Outline the main characteristics of constructive waves.
    • Smaller than 1 metre.
    • Low energy
    • Low frequency
    • Strong swash, weak backwash
    • Deposition
  • Outline the main characteristics of destructive waves.
    • Higher than 1 metre
    • High energy
    • High frequency
    • Weak swash, strong backwash
    • Erosion
  • Define the term hydraulic action.

    Waves break against the cliff face pressure of the breaking wave compresses air in the cracks. Breaks the rock apart
  • Define the term slumping.
    When land mass moves a short distance down the slope.
  • Define the term hard engineering.

    Involves the construction of man-made defences to control the natural processes, e.g. groynes + sea wall
  • Define the term soft engineering.
    Works with natural processes and considered more environmentally friendly.
  • Define the term rip rap.
    Large resistant rocks placed in front of the cliff.
  • Advantages and disadvantages of rip rap.
    • Absorbs wave energy
    • Makes beaches inaccessible
  • Define the term groynes.
    Fences built across the beach, stretching from the coastline into the sea.
  • Define the term beach replenishment.
    The addition of sand taken from somewhere (generally offshore)
  • Define the term headland.
    A cliff that sticks out into the sea
  • Define the term bay.
    A body of water partially surrounded by land.
  • Define the term stack.
    A large stack of rock in the sea
  • Define the term spit.
    Beach landform off coasts or lake shores.
  • Define the term longshore drift.
    Where materials are brought along the coastline.
  • Holderness coast
    Spurn head
  • Define the term arch.
    A wave-eroded passage through a headland.
  • Define the term wave-cut notch.
    An area of erosion at the base of a cliff formed by the waves. Formed by erosional erosional processes such as abrasion and hydraulic action
  • Define the term wave-cut platform.
    A platform that has been eroded due to the collapse of the rock below the headland due to hydraulic action and abrasion
  • what do groynes prevent?
    Longshore drift
  • Define the term coastal bar.
    A bar is created when there is a gap in the coastland with water in it.
  • Define the term salt marsh.
    Open salt water
