The Geosphere can cause earthquakes which when underwater can cause other natural disasters like tsunamis to form. These tsunamis can then kill off parts of the biosphere such as plants, humans and land animals by drowning them in the water and then dragging them back into the ocean. Environmental science as the name suggests studies the environment of our planet. However, it runs far deeper than that as environmental science also teaches us why the Earth is the way it is, how changes in it occur as well as how the Earth's systems affect things like climate changes and even natural disasters. Therefore, by understanding environmental science we can learn to predict and avoid these natural disasters in order to create a safer society. Finally, while we can't do anything to prevent or even predict the attacks of tsunamis there are still ways to avoid them. Some methods include avoiding buildings within several hundred feet of the coastline and going to a spot about 100 ft above sea level. After completing our research we were most surprised to discover how some natural disasters can have a part in creating other natural disasters. Specifically how earthquakes can cause tsunamis if caused underwater.
