The Earth is made up of four spheres. They are Atmosphere, Biosphere, Geosphere, and Hydrosphere. The Atmosphere is (air) Biosphere is responsible for maintaining life. Geosphere (Land and Rockets). Hydrosphere (water). We connected all these four elements to our natural disaster.
While doing the search on the water flood in Sierra Leone, I learned that sierra Leone is one of the wettest cities in west Africa. They once received 20 inches of rainfall in August. In our search we learned that heavy rains over saturated the ground which caused it to be waterlogged and lose friction.
