Physical Geography

1. Weather and Climate

   • The Sonoran Desert
     • Barely any rain per year
     • Diverse Plant Life
       • Adapted to Hard life
       • Giant Cactus
         • Collects water and stores it
         • They Grow Slowly
           • 200 Year Life Span!
   • Climate Change
     • Average world air temperature has increased
     • Earth's Poles have decreased in Size
       • Melted
       • Low proportion of Oxygen 18 isotopes = Warmer Climate
       • The Arctic's ice layer is thinning at a rapid rate

2. Coastal Landscapes

   • Happisburg ("Hairs-Bruhh")
     • Located on the NORTH-NORFOLK Coast
     • 25 Homes Lost.... So far....
       • Valuable Farmland Lost
         • Local Tourism and Economy has Sufferd
         • No Government money for sea Defences
       • Homes worth £1 on the Market
   • Coastal Managment
     • Hard Engineering
       • Groynes
       • Rip-rap (Stones and Boulders)
       • sea Wall
       • Soft Engineering
         • Beach Managment
         • Managed Retreat

3. Eco-Systems

   • Rainforests
     • Bio-Diversity
     • Delicate Balance
       • Water and Nutrients are Recycled in the Rainforests
         • Rainfall daily
         • Absorbed by Plants
         • Cloud cover helps the plants below from being Baked!
           • Nutrients are recycled to feed plants and other Life
   • Destruction
     • make room for farming
       • leads to soil Erosion
         • Crops then Die
         • Forests take ages to recover
     • Forests act as Tourist Hotspots

4. Rock Landscapes

   • Igneous rocks are fire formed
     • Originate from magma
       • Example = Basalt
         • Metamorphic rocks
           • Created/Formed by High Temperatures and Pressure
   • Aerial Erosion
     • Caused Rock Landscapes on Cliffs
       • Biological Weathering
       • Causes Rock to expand and Crumble

5. Glacial Landscapes

   • Glaciers leave thick areas of Sediment
     • Known as 'Drifts'
     • Particularly thick around the North Norfolk Coast
     • Material Left behind includes
       • Boulder Clay
       • Outwash
   • Ice Ages
     • Started in the UK, in the Scottish Highlands
       • Scientists are predicting the Next Ice Age
         • By Researching Ice ages that happened in the Past
           • They research glaciers out at sea

6. Natural Hazards

   • Hati Earthquake
     • Carribbean Plate
     • North American Plate
       • 3 Million people Effected
         • Over 220,000 Deaths
     • Airport and Port Destroyed
       • Epicentre = Port Au Prince

7. Rivers and water

   • Hydraulic Action
     • Attrition
       • Abrasion
         • Solution
       • High Velocity Rivers
         • Can carry Large sediment and Large Items
     • Low Velocity
       • Carries small sediment and particles
   • Rivers
     • Provide us with:
       • Energy
       • Food
       • Recreation
       • Transport Routes
     • 1, Upper Course
       • 2, Middle Course
         • 3, Lower Course
