Document Summary
Earth is made up of several interlinked systems. A system is a set of interacting and interrelated elements forming a complex whole. Systems interact with each other and their parts interact in the system. Includes gaseous part of earth from its surface to the exosphere, where the atmosphere gradually merges with space. Delicate and gives life to earth, without it we would not have lakes or oceans. Sometimes, frozen water is placed into its own system called the cryosphere. Also known as the geosphere, it encompasses solid earth, including geological material; soil (lithosphere). The layer of soil is the source of nutrients for living organisms and it provide habitats. Encompasses all life on earth; plants, animals and humans. Human presence includes; economy, culture, technology, communications, structures and other activities. Holistically (the whole picture) consider the interactions within each system and the environmental systems. Weather: state of the atmosphere at a particular place and time.
