Kia ora, over the period of time that i’ve taken in my class, I have learned much about the spheres and how each one can affect each other and be affected by outside forces.
Much of what I’ve learned is how our human activity has affected each individual sphere in unique ways that in the end affect how our world works as a whole, some of these symptoms being more notable than others.
Each sphere carries out an idiosyncrastic duty that maintains the health of our earth.
The Biosphere is the most notable sphere in my opinion as the Biosphere harbours all living things on earth, giving it far more distinctive features than any other planet in our solar system.
The Geosphere is of course an extremely important one as the Geosphere assists in life processes such as the soil that creates life and maintains ecological balance, and the most interesting thing being that the very foundation of the earth is made up by all of the sedimentaries in the Geosphere.
The Hydrosphere is of course all forms of water on earth.
Every crack and crevice has once been touched by the various liquids that fluctuate in and around the earth.
Last but not least, the Atmosphere.
The atmosphere is the earth’s very own solar shield and makes up the layers above the ground of the earth that filters out most horrible space interference.
Not only that but the various gasses in the atmosphere help to maintain almost all life on earth.
All of these elements come together in unique and diverse ways that make our planet beautiful and ever changing in nature.
Though because of our human activities such as deforestation, mining, farming and so on, a lot of problems have come to occur over the years.
Problems like eutrophication, changing weather patterns, ocean acidification and so many more have come to be, due to some of the conditions that we have set, because of our evolution of technology and ideologies.
An example of these problems from our activities would be acid rain.
Some industries use sulfur which when burned becomes sulfer dioxide or SO2 which goes up into the atmosphere to take in more oxygen and become sulfur trioxide or SO3.
Once the sulfur trioxide reaches a cloud, it fuses with the water (H2O) in the cloud to become sulfuric acid (H2SO4).
This is how acid rain comes to be and is one of many different ways that human activity can affect the earth systems.
The classes for this science have actually been very interesting and informative of all things that go on around us while we try to keep to ourselves.
I found that some of these terms related to this science are things that I already knew but didn’t know what they meant.
I have learned a lot over the time I have spent in this class and truly believe that I have a greater understanding of us as a species.
