This type of short, non-explosive volcano is often found at divergent plate boundaries
What is a shield volcano?

This device, commonly used for measuring earthquakes runs a spool of paper past a pencil or other marker
What is a seismograph?

This can be found in the Himalayas, suggesting that the plates that formed the mountains were formed under the sea
What are marine fossils?
300
Tectonic plates are neither created nor destroyed at these boundaries, but earthquakes are common
What are transform boundaries (conservative boundary is also acceptable)?
300
All faults can lead to earthquakes including the one pictured
What is a normal fault?
300
These rocks can be thrown kilometres from volcanoes and can crush buildings
What are volcanic bombs?

Following a natural disaster in 2004, Australia placed a series of deep ocean detection buoys to detect this sort of disaster
What is a tsunami?
400
These cause continental drift
What are convection currents?
400
Folded mountains such as the Himalayas are often formed when two of these plates converge
What are continental plates?
400
This scale uses numbers to describe the magnitude of earthquakes
What is the Richter scale?
400
This series of volcanoes were formed as the Pacific Plate drifted over a hot spot

The most explosive volcanoes are likely to be found at these locations
Where are the convergent boundaries?
500
These earthquake waves are the most damaging
What are Rayleigh waves?
500
These mud flows from the sides of volcanoes can cause massive amounts of damage to the natural and built environments
