Rocks

FORMATION OF GRANITE TORS

• Freeze thaw and weather wear away the granite rocks
• The sections that have no joints do not wear away as quickly as they're impermeable
• This results in an isolated outcrop of granite rock

• TOURISM- millions visit to see the landscape E.G Bowermans nose
• QUARRYING- granite is used in buildings and other famous features like Nelsons column, E.G. Meldon quarry
• FARMING- in 2000 over 290000 hectors of land for livestock
• RESEVOIRS- 8 resevoirs E.G. Burrator supplying plymouth

FORMATION OF CHALK AND CLAY LANDSCAPE

• Horizontal layers of chalk and clay tilted by earths tectonic movemoments
• The clay is soft and less resistant so erroded faster than the chalk
• the chalk is more resistant so left sticking up to form the escarpment and the slope whereas the flat clay land formed the vales

• FARMING- sheep, race horses and cows because the soil is too acidic to grow crops
• SETTLEMENTS- historical settlements like Fulking castle has high ground to defend themselves
• TOURISITS- view points on the hill to take in the amazing surroundings E.G. devils dyke
• RACE TRACK- famous epson race track located on chalk escarpment

Formation of limestone pavement

• Rain water reacts with co2 in the air to form a weak carbonic acid
• the acid chemically weathers and enlarges the joints
• this alls freeze thaw and results in clints and grikes

• TOURISM- walking, camping and over 8 million visitors to visit honey pot sites like Malhome cover
• QUARRYING- Limestone used in building as its strong an important quarry is Castle Bolton Quarry
• FARMING- Soils are thin and suitable for animals so some farmers start up B&Bs E.G. green grove country house

• SOCIAL- the quarry and cememt works have employed 300 locals which results in the multipler effect BUT noise pollution affects locals and heavy lorries increase congestion on the A6187
• ECONOMIC- huge amounts of energy needed to quarry so lots of money, employes use the local shops which means locals get pay rise
• ENVIRONMENTAL- holes ruin the landscape and cement works produce 11million tonnes of co2

• £20 million on new tram transport system instead of lorries
• reduce dust spreading and causing health problems by spraying it
• Area landscaped by 7000 trees
• restoration in areas that couldn't be quarried
• sand bags to prevent blast sound

• DURING- Hedgrows, oak trees, replacing lorries with trains
• AFTER- 2000 trees in 2004, footpaths to provide public access, 9 hole golf course in areas not being used

HOW DOES IT WORK

• Water travels through the permeable clay and it stored in the pores
• The rain water percolates through the rock and stops at the impermeable chalk
• this is called the water table
• the water runs to the london basin because london is located between Chilterns hills and the North downs
• The water is then brought up by well

+ clean, unpolluted water

+does not dry up during drought

-takes years to be replaced

-people cannot increase storage capacity
