Note: It consists of an inner core made of iron and nickel, an outer core of liquid metal, a mantle, and, on the outside, a crust.
Note: The surface of the solid Earth is in a state of constant change as the rock is moved around by the processes of plate tectonics.
Note: On the Earth's surface, the oceans and the continents form the stage on which the evolution of life takes place. The atmosphere above the surface circulates, producing the daily weather.

Earth
(1.) In the sense of soil or ground, the translation of the word _adamah'_. In Gen. 9:20 "husbandman" is literally "man of the ground or earth." Altars were to be built of earth (Ex. 20:24). Naaman asked for two mules' burden of earth (2 Kings 5:17), under the superstitious notion that Jehovah, like the gods of the heathen, could be acceptably worshipped only on his own soil. (2). As the rendering of _'erets_, it means the whole world (Gen. 1:2); the land as opposed to the sea (1:10). _Erets_ also denotes a country (21:32); a plot of ground (23:15); the ground on which a man stands (33:3); the inhabitants of the earth (6:1; 11:1); all the world except Israel (2 Chr. 13:9). In the New Testament "the earth" denotes the land of Judea (Matt. 23:35); also things carnal in contrast with things heavenly (John 3:31; Col. 3:1, 2).
earth
see down to earth; ends of the earth; four corners of the earth; move heaven and earth; not have an earthly chance; on earth; run to earth; salt of the earth.
