Rip currents: are currents of water that move with strong force out to sea and they are caused when water is pulled back out to sea by gravity and incoming waves force it back into the shore and this water mass keeps being pushed up then it finds a channel that has been formed in the floor by waves. When a rip current is formed it pushes with extreme force anything in it out to sea.
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 where they start to crash into each other and become a giant wall of water.
