Hazardous environments

Hotspot

Stationary magma plume deep in the earths surface that form volcanoes at the surface

Destructive plate boundary

• Oceanic plate moves towards a continental plate

• Oceanic plate subducts under continental plate as it is move dense

• Oceanic plate melts in the subductive zone

• Magma then rises and forms a volcano

Constructive plate boundary

• Two plates move away from each other

• Magma rises to fill the gap

• Eventually the magma cools and forms new crust

Tropical cyclones

A very powerful low-pressure weather system

Measure volcanoes

VEI

Prevent earthquake damages

• In the building of buildings add rubber shock absorbers

• These absorb the seismic waves from the earthquake

• Preventing the building from being damaged

Formation of tropical cyclone

• Warm are rises leaving behind an area of low pressure

• As the warm air rises it cools and condenses forming cumulonimbus clouds

• These clouds create the eye wall and produce heavy rainfall

• In the eye of the storm it is calm

Measure earthquakes

Richter scale

Focus

The point at which the earthquake occurs

Epicentre

The point directly above the focus at the earths surface

Predict tropical cyclones

• Use a storm tracker

• Track the weather for current tropical cyclones

Earthquakes causing tsunamis

• Earthquakes under the water

• Cause tremors in the water

• This increases the height of the waves causing a tsunami
