- Geography Revision
- Coast
- Erosional landforms
- Common features of a coastline are cliffs
- They get eroded by rainy weather and the sea crashes against the base.
- this cycle continues and the wall begins the retreat
- Caves occur when waves force their way into cracks in the cliff face. The water contains sand and other materials that grind away at the rock until the cracks become a cave.
- If the cave is formed in a headland, it may eventually break through to the other side forming an arch.
- The arch will gradually become bigger until it can no longer support the top of the arch. When the arch collapses, it leaves the headland on one side and a stack

- Food
- Biomes
- Coniferous Forest
- Higher latitudes
- Adapted to the cold
- Aeedle-like leaves
- Deciduous forest
- High rainfall
- Seasonal variations
- Trees lose their leaves in the cool winters
- Tundra
- Within the Arctic Circle
- Receives little heat from the sun.
- Little rainfall
- Tropical
- Found near the equator
- Temperature is hot
- Lot of heavy rainfall
- Desert
- Deserts are close the tropics of Cancer and Capricorn
- Hot dry air sinks down to the Earth's surface
- Sun's rays are concentrated making it very hot during the day
- Coniferous Forest
- Human impacts
- Deforestation
- Mining
- Quarrying
- Farming

- Natural Hazards
- The structure of the Earth
- The inner core
- solid and made up of iron and nickel
- 5,500°C
- The Outer core
- liquid layer, also made up of iron and nickel. It is still extremely hot, with temperatures similar to the inner core.
- The Mantle
- thickness of approximately 2,900 km.
- made up of semi-molten rock called magma
- upper parts of the mantle the rock is hard, but lower down the rock is soft
- The crust
- 0-60 km thick
- The crust is the solid rock layer upon which we live.
- There are two different types of crust: continental crust, which carries land, and oceanic crust, which carries water.
- The inner core
- Earthquakes
- An earthquake is the shaking and vibration of the Earth's crust due to movement of the Earth's plates (plate tectonics). Earthquakes can happen along any type of plate boundary.
- Earthquakes occur when tension is released from inside the crust. Plates do not always move smoothly alongside each other and sometimes get stuck. When this happens pressure builds up. When this pressure is eventually released, an earthquake tends to occur.
- The point inside the crust where the pressure is released is called the focus. The point on the Earth's surface above the focus is called the epicentre.
