What Are Spheres?
Spheres are a round solid figure, or it's surface, with every point on its surface equidistant from it's center.
A biosphere is the regions of the surface, atmosphere and hydrosphere of the earth ( or analogous parts of other planets) occupied by living organisms. Biosphere affects the earth by climate. Some produce greenhouses gases and promote warming of our planet through the greenhouse effect. Others reduce the amount of greenhouse gases.
An hydrosphere is all the waters on the earth's surface, such as lakes and seas , and sometimes including water over the earth's surface, such as clouds. The planet includes ice, water, and vapor. The hydrosphere covers about 70% of the surface of earth and is the home for many plants and animals.
A atmosphere is the envelope of gases surrounding the earth or another planet. The atmosphere consists of 78% nitrogen, 21% oxygen, 1% of water and a minute amount of the other trace gases like argon, and carbon monoxide. All gases combine to absorb ultraviolet radiation from the sun and warm the planet's surface through heat retention.
A Geosphere is any of the almost spherical concentric regions of matter that make up the earth and it's atmosphere, as the lithosphere and the hydrosphere. The geosphere is considered the portion of earth system that includes the earth's interior rocks and minerals, landforms and processes that shape the earth's surface
A Cryosphere is the frozen water part of the earth's system. One part of the cryosphere is ice that is found in water. This includes frozen parts of the ocean such as waters surrounding antarctica and the and the arctic. There are places on earth that are so cold that water is frozen solid.
