  • Interesting fact: Sharks have survived on earth for about 400 million years
    • n earth The terraqueous globe which we inhabit. It is one of the planets of the solar system, being the third in order from the sun. The figure of the earth is approximately that of an ellipsoid of revolution or oblate spheroid, the axes of which measure 12,756,506 meters and 12,713,042 meters, or 7,926 statute miles and 1,041 yards, and 7,899 statute miles and 1,023 yards, respectively, thus making the compression 1:293. The radius of the earth, considered as a sphere, is 3,958 miles. The mean density of the whole earth is 5.6, or about twice that of the crust, and its interior is probably metallic. The earth revolves upon its axis in one sidereal day, which is 3 minutes and 55.91 seconds shorter than a mean solar day. Its axis remains nearly parallel to itself, but has a large but slow gyration which produces the precession of the equinoxes. The whole earth revolves about the sun in an ellipse in one sidereal year, which is 365 days, 6, hours, 9 minutes, and 9 seconds. The ecliptic, or plane of the earth's orbit, is inclined to the equator by 23° 27° 12″ .68 mean obliquity for January 0, 1890, according to Hansen. The earth is distant from the sun by about 93,000,000 miles.
    • n earth One expression only in the Old Testament gives us the word earth in its astronomical meaning,—that in the twenty-sixth chapter of Job:—
    • n earth The solid matter of the globe, in distinction from water and air; the materials composing the solid parts of the globe; hence, the firm land of the earth's surface; the ground: as, he fell to the earth.
    • n earth The loose material of the earth's surface; the disintegrated particles of solid matter, in distinction from rock; more particularly, the combinations of particles constituting soil, mold, or dust, as opposed to unmixed sand or clay. Earth, being regarded by ancient philosophers as simple, was called an element; and in popular language we still hear of the four elements, fire, air, earth, and water.
    • n earth The inhabitants of the globe; the world.
    • n earth Dirt; hence, something low or mean.
    • n earth The hole in which a fox or other burrowing animal hides itself.
    • n earth In chem., a name formerly given to certain inodorous, dry, and uninflammable substances which are metallic oxids, but were formerly regarded as elementary bodies. They are insoluble in water, difficulty fusible, and not easily reduced to the metallic state. The most important of them are alumina, zirconia, glucina, yttria, and thorina. The alkaline earths, baryta, strontia, lime, and magnesia, have more the properties of the alkalins, being somewhat soluble in water, and having an alkaline taste and reaction.
    • n earth In electricity: The union of any point of a telegraph-line, submarine cable, or any system of conductors charged with or conveying electricity with the ground. It is generally made by joining the point at which the earth is to be established by means of a good conductor with a metallic plate buried in moist earth, or with metallic water-pipes or gas-pipes, which, on account of their large surface of contact with the earth, usually afford excellent earth-connections.
    • earth To hide in or as in the earth.
    • earth To put underground; bury; inter.
    • earth To cover with earth or mold; choke with earth.
    • earth In electricity, to put to earth; place in connection with the earth.
    • earth To retire underground; burrow, as a hunted animal.
    • n earth The act of plowing; a plowing.
    • n earth A day's plowing.
