Biologists and ecologists refer to this variety of life as biodiversity. It contains a wide range of organisms, including fungi, plants, and animals, that live together as a community. The biosphere refers to the relatively small part of Earth’s environment in which living things can survive. Both the geosphere and hydrosphere provide the habitat for the biosphere, a global ecosystem that encompasses all the living things on Earth. The geosphere includes all the rocks that make up Earth, from the partially melted rock under the crust, to ancient, towering mountains, to grains of sand on a beach. The cryosphere can also be involved in erosion, as large glaciers scour bits of rock from the bedrock beneath them.

Over time, erosion and weathering change large pieces of rocks-or even mountains-into sediments, like sand or mud.

That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth’s surface. Not only do the Earth systems overlap, they are also interconnected what affects one can affect another. Rivers and lakes may appear to be more common than are glaciers and icebergs, but around three-quarters of all the fresh water on Earth is locked up in the cryosphere. Ice, being frozen water, is part of the hydrosphere, but it is given its own name, the cryosphere. For instance, water vapor in the atmosphere is also considered to be part of the hydrosphere. All of the liquid water on Earth, both fresh and salt, makes up the hydrosphere, but it is also part of other spheres. Although liquid water is present around the globe, the vast majority of the water on Earth, a whopping 96.5 percent, is saline (salty) and is not water humans, and most other animals, can drink without processing. When observed from space, one of Earth’s most obvious features is its abundant water. All five of these enormous and complex systems interact with one another to maintain the Earth as we know it. Finally, there is the fifth system, which contains huge quantities of ice at the poles and elsewhere, constituting the cryosphere. The atmosphere is the fourth system, and it is an envelope of gas that keeps the planet warm and provides oxygen for breathing and carbon dioxide for photosynthesis. In the third system are the areas of Earth that are covered with enormous amounts of water, called the hydrosphere. The limited part of the planet that can support living things comprises the second system these regions are referred to as the biosphere. The first system, the geosphere, consists of the interior and surface of Earth, both of which are made up of rocks. There are five main systems, or spheres, on Earth. It turns out that no single feature is more significant than the others-each one plays a vital role in the function and sustainability of Earth’s system.

Eventually, however, their collective description would probably touch on all the major features and systems of our home planet. Each scientist might start with their favorite topic, from plate tectonics to rainforests and beyond.

What is the most important part of our planet, the main reason Earth is different from all the other planets in the solar system? If 10 different environmental scientists were asked this question, they would probably give 10 different answers.
