Geography Revision and Extended Research

  ( Source )  Study the diagram above and state the two circulation cells that meet at latitudes of 30 degrees North and South of the Equator.         [ 2 marks ] State - express in clear terms  So first of all look for the two command words. Actually look at the diagram, identify where the 30 degree latitude lines. Latitude lines are the ones that go horizontal.  Then write down the two cells that meet at the 30 degree line of latitude. These are Hadley  and Ferrell cells . Note that there are two answers for two marks.  Too easy for you? How about this one? Explain how global atmospheric circulation contributes towards distinctive weather and climate patterns.                                     [ 4 marks ] Explain - set out purposes or reasons So, first of all you need to know something a...

 The Guardian newspaper reports in this article that over 1,000 lives have been lost and 33 million people have been displaced and injured since June. The number of people, reported by the National Disaster Management Authority (Pakistan) , that died on Sunday was 119 and from Friday to Saturday was 45 people. Daily Mail The cause of this loss of life and damage is thought to be climate change with other contributing factors such as "the vulnerability of the poor citizens, steep mountainous slopes in some regions, the unexpected destruction of embankments and dams, and some natural climate variation." Pakistan has had an unbroken cycle of monsoon rains for eight weeks and has left a lot of infrastructural damage and a third of the country is under water. It has been  reported , by the additional deputy commissioner of Swat, that roads over 130 kilometres (80 miles) had been damaged and 15 bridges were completely destroyed as the flood wreaked havoc and more than 100 houses a...

 Taken from an article in The Guardian Weekly  " Storm Megi kills 148 with many missing feared dead .  The death toll from landslides and floods in the Philippines rose to the 148 last week with scores missing and feared dead, official said, as rescuers dug up more bodies with bare hands and backhoes in crushed villages.  Most of the deaths from tropical storm Megi - the strongest to hit the archipelago this year - were in the central province of Leyte, where a series of landslides devastated communities.  Megi, which made landfall on 11th April with sustained winds of up to 65 kph and gusts of upto 80 kph, has since dissipated.  The disaster-prone region is regularly ravaged by storms with scientists warning they are becoming more powerful as the world gets warmer because of human-driven climate change."

 Natural hazards are sudden, severe events that make the natural environment difficult to manage. They are natural processes of the planet (be it atmospheric , flooding  or geological ) but since they disrupt human life  and have huge economic  and social impacts they become natural hazards .  Atmospheric hazards include: Blizzards, Droughts, Heatwaves, Lightning & Tornadoes.  Flooding hazards include: Glacial bursts & Storm Surges  Geological hazards include: Earthquakes, Landslides, Sink Holes & Volcanic Eruptions Atmospheric combined with Flooding include: Snow Storms, Thunder Storms & Tropical Storms Flooding combined with Geological include:  Avalanches & Tsunamis Geological combined with Atmospheric include: Ash or Pyroclastic Clouds Hazards that combine Atmospheric , Flooding and Geological are mud flows or lahars Hazard risk = the chance of being affected by a natural hazard e.g. the residents of New Orlean...
