|---|---|---|---|---|---|
| 3 types of rock | igneous, metamorphic, sedimentary
🗑
|
||||
| sedimentary rock formation? | deposited sediments layer and the pressure makes sedimentary rocks
🗑
|
||||
| metamorphic rock formation? | under high pressure and temperature (changes form). higher pressure = larger grains
🗑
|
||||
| igneous rock formation? | rocks melt, cool and recrystrallize
🗑
|
||||
| intrusive igneous? | cools as it travels, hardens below ground. cools slowly. large crystals
🗑
|
||||
| extrusive igneous? | solidifies around the volcano, cools on the surface. cools fast. small crystals
🗑
|
||||
| rock cycle starting from weathering | weathering of rocks on surface, erosion and transport, deposition of sediment, burial and compaction, SEDIMENTARY ROCK, deformation and metamorphism, METAMORPHIC ROCK, melting, crystallisation of magma, IGNEOUS ROCK
🗑
|
||||
| 3 types of weathering | physical, chemical, biological
🗑
|
||||
| physical weathering | water seeps into cracks, freezes and expands, breaking the rock apart over a long time. FREEZE THAW
🗑
|
||||
| chemical weathering | slightly acidic rainwater reacts with rocks to form new minerals. ACID EROSION
🗑
|
||||
| biological weathering | plants' roots are put down cracks in the rock to find moisture. as the plant grows, the roots gradually prize the rock apart.
🗑
|
||||
| erosion | the removal of the products of weathering from where they were formed
🗑
|
||||
| how are bits of rocks transported? | wind, water, glacier
🗑
|
||||
| 3 main layers of Earth from centre | core, mantle, crust
🗑
|
||||
| inner core is in what state of matter? | solid
🗑
|
||||
| outer core is in what state of matter? | liquid
🗑
|
||||
| crust is made up of? | continental crust and oceanic crust
🗑
|
||||
| 3 properties of continental crust | thick (10-70km), buoyant (less dense than oceanic crust), mostly old
🗑
|
||||
| 3 properties of oceanic crust | thin (7km), dense (sinks under cont crust), young
🗑
|
||||
| how many major plates are there | 12
🗑
|
||||
| 3 types of plate boundaries | divergent, convergent, transform
🗑
|
||||
| divergent | plates move apart, new material is erupted to fill in the gap, ridges will spread.
🗑
|
||||
| convergent | C-C forms mountains, O-C is called subduction. oceanic lithosphere subducts under continental lithosphere. O-O forms a subduction zone
🗑
|
||||
| transform | plates slide past each other, form fault lines
🗑
|
||||
| define lithosphere | crust + upper mantle. it is rigid
🗑
|
||||
| how are plates moved around | mantle hot convection cells
🗑
|
||||
| particle size clues | if particles are close in size, well sorted (wind, water slowing down steadily). if particles are different sizes, poorly sorted (abrupt slowing down of river)
🗑
|
||||
| particle shape clues | a glacier cushions the rock so less collisions (more jagged rock).a fast-flowing river flings rocks and stones against each other (more smooth and rounded).
🗑
|
||||
| graded bedding clues | river sediment builds up on the continental shelf. if it gets dislodged it tumbles forward into deep ocean water and settles on the ocean floor.
🗑
|
||||
| cross bedding clues | layers of sediment beds lie at different angles, reflecting the direction of flow of the wind or water that deposited them. wind deposited sand dunes are often like this.
🗑
|
||||
| ripple marks clues | suggests sediment was shaped by a current of wind or water after it has been deposited
🗑
|
||||
| mud cracks clues | suggests that the watery environment in which this sediment was deposited dried up at some point.
🗑
|
||||
| aureole definition | the metamorphosed zone around the intrusion
🗑
|
||||
| contact metamorphism | rocks in contact with molten magma can undergo contact metamorphism. the change can extend from a few cm to a few km into the rock, depending on how big and hot the body of magma is.
🗑
|
||||
| regional metamorphism | rocks get buried under sediment, or trapped by large movements in earth's crust (as in mountain building). extends over 1000s of sq km.
🗑
|
||||
| dike | intrudes across rock layers
🗑
|
||||
| laccolith | mushroom-shaped
🗑
|
||||
| batholith | irregular and over 100 sq km of its surface is exposed.
🗑
|
||||
| sill | intrudes between rock layers
🗑
|
||||
| what makes magma viscous? | minerals like silica.
🗑
|
||||
| 12 main plates | pacific, fiji, scotia, nazca, eurasia, north american, south american, caribbean, antarctic, arabian, indian, australian
🗑
|
||||
| hi | hi
🗑
