- 1Types of natural hazardsHurricane, Volcanoes, Tsunami, Flood, Avalanches, Earthquakes
- 2Layers of the earthCrust, Mantle, Outer core, Inner core
- 3Convection currentsHeat moving
- 4What do we call the movement of tectonic plates?Continental Drift
- 5What currents move the Earth's tectonic plates?Heat from the decaying core
- 6CrustThinnest layer, Rock outside of Earth
- 7MantleThickest layer, Rock= Hot and Molten
- 8Outer core2nd thickest, Rock is molten
- 9Inner coreVery hot, Made of solid metal
- 10What is the name of 'super continent' that existed 200 million years ago?Pangea
- 11Convection CurrentsOccurs in the Mantle. The Mantle gets heated up due to the heat of the Earth's Core. The convection currents are hot, which means they will rise to the top, once they get there they will cool back down and sink. This continues to happen and moves the tectonic plates.
- 12Tectonic hazardsOccur on plate boundaries
- 13Continental plateThickest, Less dense, Oldest, Granite
- 14Oceanic plateThinnest, More dense, Newest, Basalt
- 15RetrofittingRetro-Old
Fitting-Put on - 16How can we measure Earthquakes?Using the Richter scale
- 175 Factors affecting the death toll of EarthquakesTime of day, Depth of focus, Time of year, Location of epicentre, Associated hazard (Tsunami)
- 18What are the 2 types of Earthquakes?Shield and Composite
- 19Shield volcanoLess viscous and occur at constructive plate boundaries
- 20Composite volcanoMore viscous, occur at destructive plate boundaries
- 21Features of an EarthquakeVolcanic bombs, Ash cloud, Pyroclastic flow, Crater, Main vent, Lava flow, Magma chamber, Secondary vent, Secondary cone
