Tectonic - Study guides, Revision notes & Summaries

Why might the level of wealth and development affect the impacts of tectonic hazards? - Answer - High levels of wealth can lead to more investment in preparedness, e.g. Japan's aseismic building architecture - Increasing poverty often leads to more shanty towns, which don't have proper building codes and are often built in vulnerable locations, e.g. favelas in Rio, Brazil Why might geographical isolation increase a population's vulnerability? - Answer More isolated communities will ...

silicates - minerals that contain silicon and oxygen and usually one or more other elements, are one of the largest groups of minerals oxides - compounds that have oxygen as their anion, t ut they exclude those with oxygen complexes such as carbonate, suphate, and silicate. have O2 as their anion, Ways rocks may form - Igneous: forms from magma that has either cooled slowly under ground or cooled quickly at the surface after a volcanic eruption Sedimentary rocks: formed when weathered frag...

big bang : -still energy left from explosion -discovered in 1960s -assumes earth came from material -Kant created most pop model of formation (planet accretion) nebula : beginning form of planets many bump into others and combine earths composition : -more dense material in center -heterogeneous (bc heat and dense elements melt and flow) 2 -accretion -compression -radioactive decay 3 layers of earth : -based on composition -core, mantle, crust -metallic core sank to center lit...

Outline the structure of the core. - Answer The core is made up of dense rocks containing iron and nickel alloys. It is divided into the solid inner core and the molten outer core, which has a temperature of over 5000C. This heat is produced due to two processes: primordial heat left over from the Earth's formation and radiogenic heat produced by the radioactive decay of isotopes. Outline the structure of the mantle. - Answer The mantle is made up of molten and semi-molten rocks contai...
