We'll be covering the different earth systems and how a change in one particular system can cause a natural disaster as devastating as hurricane Katrina.
Identification of Roles
Natural Disasters occur because of movements or changes within some of the Earth's systems. These systems include:
Biosphere ~ the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms.
Cryosphere ~ Is the frozen water part of the Earth system. Beaufort sea and North Alaska. The one part of Cryosphere is the ice that is found in the water which includes frozen parts of the ocean that surrounds Antarctica and the Arctic.
Hydrosphere ~ Hydrosphere is all of the waters on the Earth’s surface (Oceans, Lakes, etc.); including water above the surface, like in clouds. The connection Hydrosphere has with hurricanes, is the formation of them. Hurricanes start with storms over the
Atmosphere ~ The blanket of gas on the surface of a planet or satellite. The atmosphere of the Earth is about 80% nitrogen and 20% oxygen. Natural disasters include tornadoes and severe storms.
Geo-sphere ~ Any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere. Natural disasters include volcanic eruptions and earthquakes.
The earth's systems affect each other in somewhat of a domino effect. I say this because for example, a natural disaster that forms in the Atmosphere or the Hydrosphere can have a major effect on the Geosphere, possibly creating enough to cause harm to living organisms in the Biosphere. An understanding of environmental science help in natural disasters because although we can’t stop natural disasters from occurring, we can prepare for them, especially with our advancements in meteorology and forecasting natural disasters such as hurricanes. The efforts we can make to create a better future is helping those are in need of it most, and understanding that if we all pitch in, we can make recovery easier.
