Spheres of Influence: The Earth's Differentiation Into Solid, Liquid, and Gas Layers Spheres of Influence: The Earth's Differentiation Into Solid, Liquid, and Gas Layers. Any person examining their surroundings immediately realizes the vastness of what envelopes him. However, the visible objects of the Earth pale in comparison to what is going on, unseen and unnoticed. The Earth around us is divided into three layers, the gas layer (atmosphere), liquid layer (hydrosphere), and solid layer (land). These layers developed and evolved over the course of billions of years and are still changing today.

Volume of a Sphere Volume of a Sphere. A sphere is a set of points in space that are a given distance r from the center. The volume of a 3 -dimensional solid is the amount of space it occupies. Volume is measured in cubic units( in3,ft3,cm3,m3 , et cetera). Be sure that all of the measurements are in the same unit before computing the volume. The volume V of a sphere is four-thirds times pi times the radius cubed.
