Physical Geography Essay



            The Earth system is made up of different spheres. These specific subsystems operate to support life on the planet. Equally, each one functions differently but also interacting with one another to promote a specific purpose and function.

            Hydrosphere is part of the Earth system. It is comprised of all Earth’s water. Biosphere is composed of all living things on earth such as plants, animals, and the ecological communities it creates. The Atmosphere is comprised of gasses and air. This system influences the development of air temperature as well as the weather system. Lithosphere is made up of rocks and hard solid land in the Earth’s crust. Examples of these are mountains, plains, valleys etc.

            As far as interaction is concerned, a simple way that the Earth’s system interacts is through the development of rain. Specifically, this relationship happens with the atmosphere and hydrosphere. It emphasizes the process of precipitation where water is moving up from the hydrosphere to the atmosphere. This in turn influences the creation of rain clouds and after interaction with specific components provides rain.

              Another simple way to explain the Earth system interaction is through the process called photosynthesis. This is considered the process wherein plants use sunlight coming from the atmosphere to produce food for its sustenance. In turn, it also releases oxygen and helps the circulation of air in a specific area. This particular approach examines the relationship between the biosphere, atmosphere and to some extent the geosphere particularly in providing the land area where plants can grow.


            Lastly, the interaction of the Earth system can also be seen in tsunamis. Specifically, this part involves the geosphere and hydrosphere. Tsunamis usually occur when there is a movement of the Earth’s crust under water. This movement then influences the movement of waves and gives a possibility for tsunamis to occur.
