clouds
1. there are 3 main types of cloud
  1. they are
    1. curcilus nimbus which are big and fluffy. they bring short heavy showers and form high in the sky.
    2. Stratus clouds are big blankets of cloud. they are low in the sky and only drizzle with rain.
    3. Curtis clouds they are thin whispy and verry high up. freezing because they. are made from ice cristals
2. types of rainfall
  1. relph rainfall is when wind hits a mountain and on the windward side it is written but on the other side there is a rain shaddow which is a place which stays dry
  2. conventional rainfall is when the sun hears the ground causing water to evaporate. then condensation rises and starts to form clouds and when it hits due point it starts raining
tecktonicks
1. how the plates move.when the mantle gets heated it rises to the surface. when the rock gets near the crust itnstarts to harden an come back down.
layers of the earth
1. the crust is the layer we live on. this is sometimes called the skin of the earth
2. the mantle forms around hard the earth. it is made from heavy rock.
3. the core is mainly iorn. the outer core is luicuid and the inner core is solid
type of plate
1. collision plate boundary
  1. this boundary forms fold mountains
  2. this happens when to continental plates collide pushing matiriol upwards.
  3. the plates are the same density so they rise
  4. this produces earthquakes because the plates push against each other building up presure.
2. districting plate boundary
  1. this is when an oseanic plate colored with a continental plate
  2. the osianick plate sinckes beneath the continental plate because it is more dense
  3. this forms a volcano because the friction of the plate sliding under causes friction with marked the volcano erupt. this friction can also cause earthquakes.
3. Constructive plate boundary
  1. this is where two plates are pulling away from each other. then magma rises and cools to form a volcano
  2. small earthquakes happen due to the lava wanting to rise
  3. any plates can pull apart from others
4. conservative plate boundary
  1. this occurs when two plates slide next to each other in opposite directions or even sometimes in the same direction but at different speeds
  2. the friction is stored untill it cannot hold Koreans is emptied in the form of a earthquake.
Volcanoes
1. shield and composit volcanos
  1. shield
    1. less explosive eroptions
    2. the lava is very watery
    3. more frequent erouptions
    4. found at constructive plate boundaries
  2. composite
    1. explosive eroptions
    2. the magma and lava is thicker
    3. eruptions are rare
    4. found at destructive plate boundaries
2. super volcanoes
  1. the name 'super volcanoes' were first used in a dockumentary
  2. there are 7 super volcanoes in the world
rainforests
1. layers
  1. the emerjent
    1. canopy
      1. under story
        shrub layer
2. climate in the rainforest
  1. humid because of rainfall
  2. very hot
  3. it is hot because it is near the equator
3. deforestation
  1. the big trees Macke it an ideal place to harvest wood
  2. it kills animals by tackeing away their homes
weather and climate
