Rip Currents:
- If you are ever stuck in a current, swim to the right or left, not against the current.
- Currents are caused by tsunamis or earthquakes.
- When you get stuck in a very strong current, you run the risk of death.
- Usually when the waves in the ocean die down, a current will form.
Tsunamis:
- Tsunamis are affected by the shape of the ocean floor which is called topography.
- Earthquakes are the usual effect of a tsunami.
- Tsunamis are very high waves that can rip through cities and tear through houses.
- These natural disasters are very powerful and can take many lives.
Jellyfish:

- Jellyfish and many other organisms live in the Australian Ocean which has the biggest coral reef.
- When you are in the water at the beach, you must be very careful because you can easily step on a jellyfish and you WILL get stung.
- The most deadly kind of jellyfish are called irukandji.
