Definition of a Sphere A sphere is a geometrical figure that is perfectly round, 3-dimensional and circular - like a ball. Geometrically, a sphere is defined as the set of all points equidistant from a single point in space.
Sphere Interactions. The surface of the geosphere, where the rocky part of our planet is in contact with water, air, and/or life is generally where the spheres intersect and affect each other. The processes that move matter and energy from one sphere to another are called sphere interactions. Humans (biosphere) built a dam out of rock materials (geosphere). 2  Water in the lake (hydrosphere) seeps into the cliff walls behind the dam, becoming groundwater (geosphere), or evaporating into the air (atmosphere).
