Earthquakes
What is an Earthquake?
A sudden shaking of the Earth’s surface caused by movement of tectonic plates.
What is a volcano?
An opening in the Earth’s surface where magma, gas, and ash can escape.
What is a tsunami?
A series of large ocean waves caused by an underwater disturbance.
What room was our original classroom?
DC10
What two colours make purple?
Red and blue.
What do we call the point inside the Earth where an earthquake starts?
The focus (hypocentre).
What is molten rock called when it is beneath the Earth’s surface?
Magma
What is the most common cause of a tsunami?
Underwater earthquakes.
How many lessons have we completed?
17 (one above or below will be accepted)
Which sport does the NRL belong to?
Rugby League.
What is the name of the point on the Earth’s surface directly above the focus?
The epicentre
What is molten rock called once it reaches the Earth’s surface?
Lava
Why do tsunami waves increase in height as they approach the shore?
As waves enter shallow water, they slow down and build up in height.

What type of plate boundary is most commonly associated with the largest and most powerful earthquakes?
Convergent (destructive) plate boundaries.
Name one hazard caused by volcanic eruptions.
Pyroclastic flows, ashfall, lava flows, or toxic gases. (any one)
Name two impacts of tsunamis on coastal communities.
Flooding, destruction of buildings, loss of life, displacement of people, contamination of water. (any two)

In rugby league, how many players are on the field for one team at a time?
13 players.
Explain how the movement of tectonic plates causes earthquakes.
Tectonic plates move slowly but can become stuck due to friction. Stress builds up over time until it is suddenly released, causing the ground to shake as energy travels through the Earth as seismic waves.
Explain why volcanoes commonly form along tectonic plate boundaries.
Volcanoes form at plate boundaries because plates either move apart (allowing magma to rise) or collide (where one plate is subducted, melts, and forms magma), which then rises to the surface.
Explain how an underwater earthquake can generate a tsunami.
When an earthquake causes the seafloor to suddenly move up or down, it displaces a large volume of water, creating waves that travel across the ocean and grow in height near coastlines.

3 years
What is one major global issue currently affecting many countries?
Climate change, rising cost of living, or conflict. (any one)
