Document Summary
Processes and natural hazards: natural hazards can arise from three main processes: Examples of recent catastrophes: tsunami thailand, december 2004, hurricane (katrina) new orleans, august 2005, earthquake haiti, january 2010, tsunami japan, march 2011. Magnitude and frequency: the impact of a hazard is a function of both its magnitude (e. g. energy release) and frequency. It can also be affected by other factors (geology, land use urban or rural?, population density, etc. : magnitude-frequency concept there is an inverse relationship between magnitude and frequency. The rock cycle: a rock is an aggregate of one or more minerals, the rock cycle refers to a group of interrelated processes that produce the three different rock types igneous, sedimentary, metamorphic. In a given location, the types of rock give clues to geological events of the past. Population growth: human population reached 7 billion in late 2011. India and china combined account for 1/3 of earth"s population.
