ptolemaic system
Together the four spheres of the Earth make up the Earth system. These spheres are the geosphere, hydrosphere, biosphere and the atmosphere.
The main spheres or layers of Earth's atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each zone has its own distinct characteristics and plays a unique role in Earth's atmospheric processes.
The correct order of Earth's spheres from the interior to the exterior is the inner core, outer core, mantle, and crust.
Earth is composed of four main spheres: the lithosphere (solid outer layer), hydrosphere (all water on Earth), atmosphere (layer of gases surrounding Earth), and biosphere (all living organisms on Earth). These interconnected spheres work together to support life on our planet.
Earth's spheres are defined based on the different physical and chemical properties that characterize distinct regions of our planet. The main spheres are the atmosphere (air), hydrosphere (water), lithosphere (land), and biosphere (living organisms). These spheres interact and influence each other, leading to the Earth system as a whole.
Ptolemaic system
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.
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.
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.
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.
Journey to the Center of the Earth - TV series - was created in 1967.
