Rocks & Weathering
1 Rocks = mixtures of minerals
1.1 Sedimentary
1.1.1 Sediment grains stuck & deposited- soft / crumbly
1.1.1.1 eg. Sandstone
1.1.2 Porous
1.2 Metamorphic
1.2.1 Interlocking crystals due to high temp & pressure
1.2.1.1 Eg. Slate
1.2.2 Hard, smooth, shiny
1.2.3 Non-Porous
1.3 Igneous
1.3.1 Interlocking crystals
1.3.2 Molten rock cools & solidifies
1.3.3 Very hard
1.3.3.1 eg. Granite
1.3.4 Non-Porous
1.4 Porous rocks
1.4.1 Grains = gaps so water / air gets in
1.4.1.1 Bubbles appear if put in water, as air escapes
1.4.1.1.1 Mass increases in water
1.5 Non-Porous rocks
1.5.1 Interlocking = no gaps for air / water
2 Physical Weathering
2.1 Temp breaks down rocks
2.1.1 Freeze-thaw
2.1.2 Onion skin - expand contract
3 Landscapes & Weathering
3.1 Scree slope at bottom of cliffs as breakdown & fall
4 Rain & Weathering
4.1 Rain = acidic - chemical weathering on rocks
4.1.1 Pollution eg. sulphur dioxide = speeds up weathering
4.1.1.1 Rocks change colour
5 Transportation
5.1 Pieces of rock - transported by glaciers
5.1.1 Glaciers = slow moving rivers of ice
5.1.1.1 Rocks carried then deposited when melting
5.1.1.1.1 Smaller rocks carried further
6 Evaporates
6.1 Salts in water evapotae - leave sediment
7 Fossils
7.1 Remains of plants & animals in sedimentary rocks
7.1.1 Fossil fuels = coal, oil, gas - take millions of years to form & non-renewable
