sphero-, spher-, -sphere-

(Greek: ball, round, around; globe, global; body of globular form; by extension, circular zone, circular area)

earth spinning.
Relatively thin life-supporting areas of the earth's surface, extending from a few miles into the atmosphere to the deep-sea vents of the oceans.

The biospheres are global ecosystems that can be broken down into regional or local ecosystems, or biomes.

Organisms in the biospheres are classified into trophic levels (steps) and communities.

blastosphere, blastula
1. An embryo at an early stage of development, consisting of a hollow ball of cells.
2. An early embryonic form produced by cleavage of a fertilized ovum and consisting of a spherical layer of cells surrounding a fluid-filled cavity.
3. An animal embryo at the stage immediately following the division of the fertilized egg cell, consisting of a ball-shaped layer of cells around a fluid-filled cavity known as a blastocoel.
blogosphere, blogsphere
1. All of the blogs on the internet, and the people who write or read them.
2. The total universe of blogs and the collection of all bloggers, blog sites, blog readers, and blog texts or contents.
3. The current state of all information available on blogs and/or the sub-culture of those who create and use blogs.
celestial sphere (s) (noun), celestial spheres (pl)
1. The imaginary orbit around the Earth: The sun, moon, stars, and planets appear to be placed on the celestial sphere.
2. The imaginary shell formed by the sky: The celestial sphere is usually, represented as an infinite circle, the center of which is the observer's position.
The central or interior portion of the earth.
chemical lithosphere
The chemical boundary layer between the surface of the earth and the asthenosphere that contains the material differentiated or extracted from the mantle.
The portion of the earth's atmosphere, 30-80 kilometers, or 20 to 120 miles, above the earth's surface, where chemical (especially photochemical) activity is most intense.

It encompasses the stratosphere, the mesophere, and possibly a part of the thermosphere.

1. A creative LED [l(ight-)e(mitting) d(iode)] a semiconductor diode that converts applied voltage to light and is used in lamps and digital displays which can be controlled to generate any color via a light panel or remotely by a switch.

These frosted polyethylene spheres are illuminated with high-power LED's and are designed for both indoor and outdoor applications.

2. A sphere, internally illuminated with high-power LED's enabling the sphere to be changed to any color a person desires.
chromosphere (s) (noun), chromospheres (pl)
1. A gaseous layer of the sun's atmosphere; extending from the photosphere to the corona, that is visible during a total eclipse of the sun.
2. A scarlet, gaseous envelope surrounding the sun outside the photosphere, from which enormous quantities of hydrogen and other gases are erupted.
3. A layer of rarefied, transparent gases in the solar atmosphere which measures 6,000 miles (9,700 kilometers) in thickness and lies between the photosphere (the sun's visible surface) and the corona (its outer atmosphere).
4. A gaseous envelope surrounding a star.
A reference to an incandescent, transparent layer of gas, primarily hydrogen, several thousand miles in depth, which lies above and surrounds the photosphere (intensely bright part) of the sun but is distinctly separate from the corona (luminous envelope surrounding the sun).
The world's first permanent IMAX (motion picture film format) theater, built in 1971.

Its design which is similar to that of Spaceship Earth is the icon of Walt Disney World's Epcot theme park.

It consists of a triodetic-domed structure (related to a geodesic dome, consisting of 1,490 acrylic glass bubbles and is illuminated at night).

circumsphere (s) (noun), circumspheres (pl)
In geometry, a circumscribed sphere of a polyhedron which is a sphere that contains the polyhedron and touches each of the polyhedron's vertices (the points of geometric figures that are opposite their bases).
A small, rounded, marine organism, capable of braking up into coccoliths or microscopic structures of varying shapes and sizes that are made of calcite, are secreted by calcareous nannoplankton, and form chalk and limestone when fossilized.

Coccoliths range in size from one to thirty-five micrometers in size.

1. The material universe.
2. An apparatus for showing the position of the earth, at any given time, with respect to the fixed stars.

It consists of a hollow glass globe, on which are depicted the stars and constellations, and within which is a terrestrial globe.
