- - - - The breakdown of rocks on the surface from rainwater, extreme temperature and biological activities.
      - The process of rocks wearing away and moved elsewhere by wind, water and rain.
    - - Small amounts of water can break even the hardest rocks. When water seeps in to cracks and freezes, the ice expands and increases the size of the crack. Over time this process will pry the rock open.
    - - This type of weathering is common in warm areas because the sun shines on rocks during the day. This process causes the rocks to expand, at night the rocks contract in colder temperatures. Over time, the continued process will cause pieces of rock to fall off.
    - - Caused by rain water reacting with minerals in rocks to form new minerals like clay and salts. This occurs when the water is slightly acidic.
    - - The effect of living things such as the roots of trees growing in to rocks and pry them apart .
    - - The three main threats to coastlines are tourism, pollution and loss of marine biodiversity
    - - In the Victorian coastlines lie the twelve apostles, though only 7 remain due to erosion from ocean waves.
    - - The worlds largest coral reef, it contains over 300 different reef systems and is one of the seven wonders of the world. The great barrier reef is one of the most popular tourist destinations.
    - - The Australian bight is a continuous line of cliffs which stretch along Australia's southern coast. These cliffs reach up to 60 - 120 metres high.
  - - - Volcanoes are openings in the Earths crust where lava and hot gas is stored
        
        Active volcanoes have a reputation of eruptions and is likely to happen again
        
        Mount Vesuvius is an active stratovolcano which is known for its eruption in 79 CE that destroyed Pompeii while preserving the remains. The eruption destroyed the city in under 25 hours and over 30 000 people were killed.
        
        Extinct volcanoes will not erupt in the future.
        
        Dormant volcanoes have not erupted in a long time but may erupt in the future.
    - - The Ring of fire is an area on the edge of the Pacific ocean where the Pacific plate and neighbouring plates move and cause earthquakes, tsunamis and volcanoes.
    - - The Earth is made up of plates that are moved a molten layer of rock. The plates move at different speeds to each other which can cause plates to slide and hit each other.
  - - - Fold mountains are created by upward pressure where two tectonic plates collide, pushing rock upwards and forming mountains.
      - Volcanic mountains are created by volcanoes when magma is pushed to the surface.
      - Block mountains are created from faults in the crust, when a slab of land has broken off. The two neighboring plates start pushing and pulling together to form new land, which will create a mountain
- - - - The Prime meridian is a line that goes split down the middle of the Earth. It determines the 24 hour time zones.
    - - The Equator is a lines splitting the Earth in to two hemispheres, the North and South.
      - Tropic of Capricorn is a line of latitude located 23.5 degrees South of the Equator, forming the tropical climate zone.
      - Tropic of Cancer is a line of latitude located in 23.5 degrees North of the Equator, where the sun is directly overhead
  - - - There are 11 different types of maps
