Tsunamis

A Tsunami is a big wave usually caused by an earthquake on the Earth surface. The 4 spheres that make up the Earth's systems are disturbed by the disaster. The ozone layer, clouds (atmosphere), the ocean is forced from it's homeostasis to a raging destructive wave (hydrosphere), the land nearby is destroyed (lithosphere) , and the people nearby are dead or homeless. The kinetic energy that builds up in the wave starting from the earthquake is the reason the rest of the spheres are affected. People could grow mangroves and teach their young to take care of them, people can make shelter high up and overall be aware of their environment because they could possibly have a Tsunami in their area.
