A very important linking sphere is the biosphere, the study of which is biology. The biosphere consists of all forms of life, from single-celled organisms to pine trees to people. The interactions of Earth’s other spheres – lithosphere/geosphere, hydrosphere, atmosphere and/or cryosphere and pedosphere – create the conditions that can support life.
