- Hello! My name is Jersey.Today you're going to take a short tour with me into four major subsystems of the Earth. Ready?
- Here we go!
- Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). Each of these four spheres can be further divided into sub-spheres.

- The Atmosphere contains all the air in Earth's system.
- The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. When air temperature in the lower portion of this sphere changes, weather occurs. As air in the lower atmosphere is heated or cooled, it moves around the planet. The result can be as simple as a breeze or as complex as a tornado.

- The Biosphere contains all the planet's living things.
- This sphere includes all of the microorganisms, plants, and animals of Earth. Within the biosphere, living things form ecological communities based on the physical surroundings of an area. These communities are referred to as biomes. Deserts, grasslands, and tropical rainforests are three of the many types of biomes that exist within the biosphere.

- The Geospherecontains all of the cold, hard solid land of the planet's crust (surface), the semi-solid land underneath the crust, and the liquid land near the center of the planet.
- The outermost layer of the lithosphere consists of loose soil rich in nutrients, oxygen, and silicon. Beneath that layer lies a very thin, solid crust of oxygen and silicon. Next is a thick, semi-solid mantle of oxygen, silicon, iron, and magnesium. Below that is a liquid outer core of nickel and iron. At the center of Earth is a solid inner core of nickel and iron.

- The Hydrospherecontains all the solid, liquid, and gaseous water of the planet.
- A small portion of the water in the hydrosphere is fresh (non-salty). Most of Earth's fresh water, however, is frozen.Ninety-seven percent of Earth's water is salty. The salty water collects in deep valleys along Earth's surface. These large collections of salty water are referred to as oceans.The differences in temperature cause water to change physical states.

- Join me again in our next adventure, will you?
- Although the four systems have their individual identities, there is important interaction between them. Environmental scientists study the effects of events in one sphere on the other spheres. There are ten possible types of interactions that could occur within the earth system.
