What is the theory of continental drift?
The theory that states the continents move apart due to convection currents in the asthenosphere
1 of 8
What is slab pull theory?
The process of a tectonic plate descending into the mantle is named subduction, and slab pull occurs when an oceanic plate subducts into the underlying mantle
2 of 8
What are the 3 main types of volcanoes?
Composite, shield and dome, composite volcanoes often known as strato volcanoes due to their steep sided cones formed from several layers of ash
3 of 8
Name the 3 C/S for Earthquakes
Haiti, Sichuan, and Japan earthquake and tsunami, All showing different levels of devlopment and how it was dealt with in terms of the countries level of development
4 of 8
Name the 3 steps of a Tsunami forming
1. Generation of a tsunami in deep ocean 2. Tsunami run up 3.Landfall
5 of 8
What is the formula for hazard risk?
Risk(R) = Hazard(H) x Vulnerability(V) / Capacity to cope(C)
6 of 8
What is the Park model and what does it show?
The park model is a hazard reponse curve demonstrating how a country or region may respond after a hazard or catastrophe. It can be used to show the differing levels of development in different areas and how they may recover
7 of 8
What are the 4 stages to the hazard management cycle?
Mitigation (prevention), Preparedness, Response, recovery
