1. Unit 2-Living with the physical environment Part 1-The challenges of hazards What is a hazard? Define the term natural hazards Identify and describe the types of natural hazard Assess the factors that affect the risk of a hazard. http://www.s-cool.co.uk/a-level/geography/natural-hazards/revise-it/natural- hazards

2. How do we define a natural hazard? A natural hazard is a naturally occurring event that might have a negative effect on people or the environment.

3. What types of natural hazards do we have? https://www.youtube.com/watch ?v=zQYe3ngG6qs Natural Hazards Work as a team to come up with as many natural hazards as you can-remember they must be natural-not man made….3 mins Now watch the following clip-can you add any more… Natural hazard events can be grouped into two broad categories. Geographical hazards encompass geological and weather phenomena such as earthquakes, coastal erosion, volcanic eruption, cyclonic storms, and drought. Biological hazards can refer to a vast array of disease and infestation. Other natural hazards such as floods and wildfires can result from a combination of geological, hydrological, and climatic factors.

4. What hazard does this present that may make it a Natural Disaster? Add to your thoughts describing the risk that is posed. One has been done for you… Volcano Ash cloud-problems breathing Lava-burning settlements and crops Falling debris-risk of death/fire

5. Read carefully through the information below. Decide if it is a physical or human factor that is affecting the risk from a hazard. Be ready to share your reasons…  Distance from the event - the effects of a hazard are often more severe the closer you are.  The intensity of the hazard-the greater the event the worse the risk.  Level of development (MEDC or LEDC) - MEDCs are more likely to have the resources and technology to prepare and respond to hazards.  Population density (rural or urban area). The more densely populated an area, the more likely there are to be deaths and casualties.  Communication links – accessible road networks allow emergency teams and resources in.  Time of day influences whether people are in their homes, at work or travelling. A severe hazard at rush hour in a densely populated urban area could have devastating effects.  The time of year and climate will influence survival rates and the rate at which disease can spread after the event. What factors affect the risk of a hazard?
