Concept 1
An event (naturally occurring) which has the potential to cause loss of life or property.
A hazard
The boundary where two plates slide past one another.
What is a Transform boundary ?
Where plates move away from one another often causing trenches.
What are divergent boundaries ?
A special type of wave where the sea or ocean is set in motion by an event, often an earthquake, which displaces the water above it and creates a huge wave.
What is a tsunami?
Hurricanes, and typhoons occur in which hemisphere?
What is the northern hemisphere?
Earthquakes, volcanoes and tsunami’s are caused by what geophysical process?
What is geological?
An area of low pressure with winds moving in a spiral around the calm central point called the eye of the storm. The winds are powerful and rainfall is heavy.
What is a cyclone?
The after-effects that occur as indirect impacts of a natural event, sometimes on a longer timescale, for instance fires due to ruptured gas mains resulting from the ground shaking.
What are Secondary Hazards?
Tsunamis are a specific secondary effect caused by what type of hazard?
What is an earthquake?
This event is characterized by unusually cold ocean temperatures in the Equatorial Pacific and flooding and heavy rain serious typhoons, hurricanes and very cold weather in various parts of the world.
What is La Nina?
Cyclones, storms and tornados are all examples of what type of geophysical process?
What is atmospheric?
The initial impact of a natural event on people and property, caused directly by it, for instance the ground buildings collapsing following an earthquake.
What is Primary Hazard?
The point at the Earth’s surface directly above the focus.
What is the epicenter?
The abnormal rise in seawater level during a storm, measured as the height of the water above the normal predicted astronomical tide.
What is a storm surge?
At which geographic coordinates do tropical storms occur?
What is 5 to 30 degrees north or south of the equator.
Tectonic plate margin where two plates are moving towards each other or coming together and the oceanic plate is subducted. It can be associated with violent earthquakes and explosive volcanoes.
What is Convergent boundary?
Action taken to reduce or eliminate the long-term risk to human life and property from natural hazards, such as building earthquake-proof buildings
What is mitigation?
Waves that transmit the energy released by an earthquake.
What is seismic waves?
Tropical storms do not form at the this location as there is not enough spin from the earth’s rotation.
What is the equator?
an effect whereby a mass moving in a rotating system experiences a force acting perpendicular to the direction of motion and to the axis of rotation.
What is the Coriolis Effect ?
Actions taken to enable communities to respond to, and recover from, natural disasters, through measures such as emergency evacuation plans, information management, communications and warning systems.
What is planning?
The process of a more dense lithospheric plate going under a less dense plate.
What is Subduction ?
a sudden and terrible event in nature (such as a hurricane, tornado, or flood) that usually results in serious damage and many deaths.
What is a disaster?
Tropical storms form over warm oceans where the water temperature is at.
What is 27 degrees celcius?
The area of a cyclone around which all the winds accumulate.
What is the eye?
