Layer vs. Sphere — What's the Difference?

A sheet, quantity, or thickness of material, typically one of several, covering a surface or body

A sphere (from Greek σφαῖρα—sphaira, "globe, ball") is a geometrical object in three-dimensional space that is the surface of a ball (viz., analogous to the circular objects in two dimensions, where a "circle" circumscribes its "disk"). Like a circle in a two-dimensional space, a sphere is defined mathematically as the set of points that are all at the same distance r from a given point in a three-dimensional space.

A person or thing that lays something

A round solid figure, or its surface, with every point on its surface equidistant from its centre.

A shoot fastened down to take root while attached to the parent plant

Arrange in a layer or layers

Enclose in or as if in a sphere

Propagate (a plant) as a layer

(Mathematics) A three-dimensional surface, all points of which are equidistant from a fixed point.

To divide or form into layers

To form into a sphere.

To cut (hair) into different, usually overlapping lengths.

(Botany) To take root as a result of layering.

Any of the concentric hollow transparent globes formerly believed to rotate around the Earth, and which carried the heavenly bodies; there were originally believed to be eight, and later nine and ten; friction between them was thought to cause a harmonious sound (the music of the spheres).

A single thickness of some material covering a surface.

(mythology) An area of activity for a planet; or by extension, an area of influence for a god, hero etc.

An item of clothing worn under or over another.

(figuratively) The region in which something or someone is active; one's province, domain.

A (usually) horizontal deposit; a stratum.

One of the items in a hierarchy.

(logic) The extension of a general conception, or the totality of the individuals or species to which it may be applied.

One in a stack of (initially transparent) drawing surfaces that comprise an image; used to keep elements of an image separate so that they can be modified independently from one another.

(transitive) To place in a sphere, or among the spheres; to ensphere.

A person who lays anything, such as tiles or a wager.

(transitive) To make round or spherical; to perfect.

A mature female bird, insect, etc. that is able to lay eggs.

A body or space contained under a single surface, which in every part is equally distant from a point within called its center.

A hen kept to lay eggs.

Hence, any globe or globular body, especially a celestial one, as the sun, a planet, or the earth.

A shoot of a plant, laid underground for growth.

The apparent surface of the heavens, which is assumed to be spherical and everywhere equally distant, in which the heavenly bodies appear to have their places, and on which the various astronomical circles, as of right ascension and declination, the equator, ecliptic, etc., are conceived to be drawn; an ideal geometrical sphere, with the astronomical and geographical circles in their proper positions on it.
