The four spheres of the Earth are the atmosphere, the biosphere, the hydrosphere and the lithosphere. Each of these spheres is considered by scientists as interconnected in a greater geosphere that harbors all terrestrial life and materials.


A sphere is a solid geometric figure defined as the set of all points equidistant from a common center point. It is perfectly symmetrical, and its surface is uniformly curved, without any edges, vertices or faces. It is the shape made when a semi-circle is rotated around its diameter.


A sphere is a round-shaped object in three-dimensional space. All points on a sphere's surface are the same distance from its center point. Some examples of a sphere are a globe, marble, soccer ball and basketball.


Half a sphere is defined as a hemisphere. The term hemisphere is derived from the Greek word "hemi," which means "half" and the Latin word "shaera," meaning "globe."


The volume of a sphere is found by multiplying four-thirds by pi by radius cubed. The Greek mathematician Archimedes first derived this formula. He also found that the surface area of a sphere equals four by pi by radius squared.


One way to draw a sphere is to draw a circle and shade it with a crayon. You need a sheet of paper, a crayon, a pencil, a cotton ball, an eraser, a compass and a drawing board to accomplish this task.


A sphere has no faces. A sphere is defined as a round symmetrical object, while a face is defined a flat surface of an object. By definition a sphere does not have any faces.


To find the surface area of a sphere, use the formula 4(pi)r2. In this formula, r is equivalent to the radius. Pi represents the infinite number 3.141592..., which is usually rounded to 3.14.


A sphere lacks edges. Edges are associated with faces and are found in shapes like squares and rectangles. Because of the round shape of a sphere, it lacks faces.


A sphere can be made out of paper by using origami techniques to fold the paper several different ways and pushing it out to make it appear as a spherical shape. It is a moderately easy origami project.
