Aristotle believed that the universe was made up of a series of concentric spheres, with Earth at the center. He thought that the stars and planets were embedded in these spheres and that they moved in circular orbits around the Earth.
"Geocentric".
Aristotle believed that the Earth was at the center of the universe, with all other celestial bodies revolving around it in a series of concentric spheres. This geocentric view of the universe contrasted with the later heliocentric model proposed by Copernicus.
This idea, known as the geocentric model, was a widely held belief in ancient times that placed Earth at the center of the universe with celestial bodies moving around it in concentric spheres. This view was eventually replaced by the heliocentric model proposed by Copernicus, which correctly positioned the Sun at the center of the solar system. The geocentric model was influenced by observations that seemed to support Earth being stationary and everything else revolving around it.
Aristotle believed that the universe was geocentric, with Earth at the center and celestial bodies moving in perfect circular orbits around it. He also thought that the universe was eternal and unchanging, consisting of a series of concentric spheres made of a quintessential fifth element, ether.
Aristotle believed in a geocentric model of the universe, with Earth at the center and celestial bodies orbiting around it in concentric spheres. He also theorized that the universe was eternal and unchanging.
The Earth's mantle is below the crust. The layers of the Earth form concentric spheres. Below the mantle is the core.

Aristotle believed that the universe was eternal and unchanging, with Earth at its center. He theorized that the stars and planets were embedded in a series of concentric spheres that rotated around the Earth. Aristotle also believed in the concept of natural motion and the existence of a fifth element, or quintessence, which made up the heavenly bodies.
The Greeks believed in a geocentric universe, where Earth was at the center and celestial bodies like the sun, moon, planets, and stars orbited around it in circular paths. They envisioned a series of concentric spheres surrounding Earth with each sphere carrying a celestial body. This model was known as the Ptolemaic system.
Aristotle's model of the universe took into account the charted movements of the heavenly bodies, but was complicated by the assumption that Earth lay at the center of the universe.
