GLOBAL GEOGRAPHICAL ISSUES HAZARDOUS EARTH 1a: CLIMATE CHANGE How does the world’s climate system function, why does it change and how can this be hazardous for people? Global atmospheric circulation – how circulation cells and ocean currents transfer and redistribute heat energy around the earth and determine the location of high pressure (arid) and low pressure (high rainfall) areas. Natural causes of climate change. Evidence for natural climate change. How human activities produce greenhouse gases that cause the enhanced greenhouse effect leading to global warming. Evidence for how human activity is causing climate change. The range of projections for global temperature change and sea level rise 1b: EXTREME WEATHER How are extreme weather events increasingly hazardous for people? Characteristics and seasonal global distribution of tropical cyclones. How the global circulation of the atmosphere leads to tropical cyclones in source areas (reasons why some tropical cyclones intensify and their dissipation). Physical hazards of tropical cyclones and their impact on people and environments. Why some countries are more vulnerable than others to the impacts of tropical cyclones. How countries can prepare for, and respond to, tropical cyclones. The effectiveness of preparation / response in one developed country and one developing / emerging country. 1c: TECTONIC HAZARDS Why do the causes and impacts of tectonic activity and management of tectonic hazards vary with location? The composition and properties of each of the layers of the Earth (including the asthenosphere). How the core’s internal heat source generates convection. Distribution and characteristics of the three plate boundary types (convergent / divergent / conservative). Causes of contrasting volcanic and earthquake hazards (including tsunami). Primary and secondary impacts of earthquakes OR volcanoes on property and people in a developed and emerging or developing country. Management of volcanic or earthquake hazards in a developed and emerging / developing country (including short-term relief, long-term planning, preparation and prediction). business (es) Arctic divergent environment (al) boundary secondary government (al) conservative tsunami infrastructure convergent volcano
