AQA GCSE - Tectonic hazards keywords

What is the keyword for the following definition: Tectonic plate margin where rising magma adds new material to plates that are diverging or moving apart.

Define Hazard Risk

• A sudden or violent movement within the Earth’s crust followed by a series of shocks.

• The probability or chance that a natural hazard may take place.

• A natural event (for example an earthquake, volcanic eruption, tropical storm, flood) that threatens people or has the potential to cause damage, destruction and death.

Define Plate margin

What is the keyword for this definition: Tectonic plate margin where two plates are converging or coming together and oceanic plate is subducted. It can be associated with violent earthquakes and explosive volcanoes.

• Destructive plate margin

• Constructive plate margin

• Conservative plate margin

• Dinner plate margin

What is the keyword for the definition: A sudden or violent movement within the Earth’s crust followed by a series of shocks.

• Natural Hazard

• Tsunami

• Volcano

• Earthquake

What is the key word for the definition: Recording physical changes, such as earthquake tremors around a volcano or tracking a tropical storm by satellite, to help forecast when and where a natural hazard might strike.

What is the keyword for this definition: A natural event (for example an earthquake, volcanic eruption, tropical storm, flood) that threatens people or has the potential to cause damage, destruction and death.

Define: Volcano

What is the keyword for the definition: A rigid segment of the Earth’s crust which can ‘float’ across the heavier, semi-molten rock below. Continental plates are less dense, but thicker than oceanic plates.

Immediate responses are: The reaction of people as the disaster happens and in the immediate aftermath.
