        Terminology
        
        Hypocentre/Focus - Origin of the earthquake
        
        Epicentre - The surface of the Earth that’s directly above the focus
        
        Seismic Waves - Vibrations caused by the focus
        
        Fault - A fracture in the rocks that make up the Earth’s crust
        
        Seismograph - Measures the intensity of the earthquake
        
        5.0 - Can cause damage
        
        6.0 - Very strong
        
        2.0 or less - harmless
        
        Richter scale
        
        7.0 - Major earthquake

  - - - Sea
        
        Waves strike against rocks, eroding them away to create holes
        
        Sea Caves
        
        The holes become bigger and eventually create a tunnel like structure
        
        Sea Arches
        
        Ceiling collapses

      - Glaciers
        
        Glacial Lakes
        
        Glaciers erode away soil to create hollows in the ground. When the ice melts, the hollows fill up with water.
        
        Glacial Moraines
        
        Deposited rocks, sand and silt
      - River
        
        Ox-bow Lake
        
        As soil gets deposited in the inner curve of the meander, gradually the meander gets cut off, creating an ox-bow lake.
        
        Floodplain
        
        When a river floods, eroded material is deposited along the banks, making a flat fertile floodplain.
        
        Meanders
        
        When the river enters the plains it twists and turns to create a meander
        
        Levees
        
        The raised banks created due to floodplains are called levees
        
        Waterfall
        
        When a river shifts from hard rock to soft rocks, the soft rocks erode away to create a cliff-like-structure for the land.
        
        Delta
        
        As rivers near the basin, they deposit most of their loads, dividing the river into distributaries with their own mouth.

        Desert
        
        Sand Dunes
        
        A loose mound of sand shaped by the wind
        
        Sand dune facts
        
        Slack - The valley between sand dunes
        
        Dune field - A collection of dunes
        
        Erg - A large dune field
        
        Mushroom Rocks
        
        Created when the lower section of a rock is eroded to a great extent, and the upper section almost untouched. This causes the rock to have a narrow base and wide top, like a mushroom.
        
        Loess
        
        Similar to sand dunes, a loess is a yellowish grey deposit of sediments.
