Ocean Hazard Notes
Tsunamis: Tsunamis are one of the most dangerous threats of the ocean. Tsunamis are made when two plates collide and make an enormous pressure. That pressure is brought to the surface of the ocean and makes four-way waves. Those are the tsunamis. They look like normal waves until they reach the coasts and beaches.
Rip Currents: Rip currents are another one of the most dangerous threats of the ocean. Rip currents are made by breakers cross sand bars off the shore. The water travels back to sea through the gaps in the sand bar, creating a rip current. People caught up in the rip currents end being drag out more to sea and drowning.
Jelly Fish: Along with tsunamis and rip currents, jellyfish are also a big threat in oceans. People may get stung by one due to shared habitats when you are swimming in the Great Barrier Reef. Some chances are they might get stung by the box jellyfish or the Irukandji jellyfish. Both the Irukandji and the Box jellyfish like warm waters, so when it becomes summertime, more jellyfish appear. The fact that we're hunting more fish means more room for jellyfish.
