Last lesson, the Earth shook from below. Today, the forces come from water and weather — tsunamis, cyclones and floods — and we look at how communities prepare for them.
A tsunami isn't one big surfing wave — it's a huge amount of energy travelling through the water. Watch where it starts.
Extreme weather reshapes the land and affects communities. In Australia, three types matter most.
| Event | What it does | Australian example |
|---|---|---|
| Cyclone | Strong winds (over 200 km/h) + storm surge erode coasts and flatten trees | Cyclone Yasi (2011), Qld |
| Flood | Moving water erodes soil, deposits mud, damages homes | 2022 Eastern Australia floods |
| Extreme heat & drought | Dries the land, raises bushfire risk, stresses living things | Black Summer bushfires (2019–20) |
People can't stop these events — but science helps them predict, prepare and respond, which saves lives.
In your groups, analyse a real case-study card with data. We'll model the first one together.
On your own, write a short structured summary of one extreme event.
For a tsunami, also sketch and label the cause-to-coast energy chain:
