- THE STRUCTURE OF THE EARTH
- mutual core - björk
- crust
- mantle
- core
- tectonic plates
- sudden movement causes earthquakes
- wegner's theory of continental drift
- continents slot together like jigsaw
- similar fossils on each side of the atlantic
- matching layers in the rocks
- wasn't widely accepted at first
- scientists thought it was impossible with the forces being too strong
- he used inaccurate data
- he wasn't a geologist
- EMULSIONS
- oil and water
- don't mix
- can mix with an emulsifier
- hydrophilic tail for water molecules
- hydrophobic head for oil molecules
- oil and water
- PLANT OILS
- unsaturated
- healthy
- double carbon bonds
- can be hydrogenated
- food, cooking, cosmetics, fuels
- crushed and pressed to get the oil
- unsaturated
- ALKENES
- makes polymers
- small monomers joined to make one long molecule
- double carbon bond C=C
- makes polymers
- CRUDE OIL
- cracking
- splittingup long hydrocarbons
- passing vapour over a hot catalyst
- cracking
- CRUDE OIL
- mostly alkanes
- CnH2n+2
- shorter = more viscous
- hydrocarbons
- used as fuel
- will eventually run out
- cause environmental problems
- releases gases
- causes acid rain
- climate change
- global dimming
- fractional distillation
- heated and tapped off at different temperatures for different uses
- mixture of hydrocarbons
- mostly alkanes
- ALLOYS
- pure metal not strong because it's in layers - can slide around
- more than one metal = stronger
- disrupts pattern so harder to slide layers
- EXTRACTING METALS
- ores
- reduction
- using carbon
- can be extracted with reduction if not very reactive
- carbon takes away oxygen
- electrolysis
- used for more reactivemetals
- splittingup with electricity
- LIMESTONE
- calcium carbonate
- CaCO3
- limestone cycle
- calcium carbonate -> calcium oxide -> calcium hydroxide -> calcium hydroxide solution-> calciumcarbonate
- quarrying
- scars landscape
- pollution
- creates jobs
- creates local economy
- calcium carbonate
- summary
- PERIODIC TABLE
- periodic table grime song
- THE STRUCTURE OF THE EARTH
