Why do planets have layers?
Planets have layers due to a process called differentiation, where heavier materials sink towards the center and lighter materials rise to the surface. This creates distinct layers with different compositions and properties. For example, Earth has layers like the crust, mantle, outer core, and inner core, each with its own characteristics based on the materials present.
What is Saturn's crust made of?
Saturn does not have a solid surface like planets such as Earth. Its upper layers are made of gases, primarily hydrogen and helium. Below these layers is a liquid metallic hydrogen layer, which transitions into a rocky core at the center of the planet.
How many layers in earths mantle?
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
What type of model is a heliocentric?
A heliocentric model is a model of the solar system where the Sun is at the center and the planets orbit around it. This is in contrast to the geocentric model, where Earth is considered to be the center of the universe.
Aristotles study about the solar system?
he thought the earth was the center of the universe and the sun and the planets orbiting the earth. but he was wrong.

Why the center of the earth is so deep?
The center of the earth is deep because the earth is composed of layers, with the core being at the very center. The intense pressure and heat from the weight of the layers above push the core deeper into the earth.
Which of the earth's atmospheric layers is the closest to the earth's?
troposphere
What is Saturn's crust made of?
Saturn does not have a solid surface like planets such as Earth. Its upper layers are made of gases, primarily hydrogen and helium. Below these layers is a liquid metallic hydrogen layer, which transitions into a rocky core at the center of the planet.
What are five layers of the earth in order from the outside the center of the earth?
The five layers of the Earth, from the outside to the center, are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.
How do earths layers contribute to the planets physical characteristics?
The Earth's layers contribute to the planet's physical characteristics by the types of rocks these layers produce. The rock formation of the Earth's surface define the physical characteristics of the planet.
Why the earth is not the center of the milky way?
Earth is a planet. Center's of galaxies sometimes contain black holes. Planets can't be black holes.
In the geocentric model do the planets travel around the stars?
The syllable "geo-" always has something to do with the earth. The "geo-" "-centric" model has the earth at the center, and the planets revolving around the earth.
In what part of the atmosphere does a space ship fly?
The Earth's exosphere extends ~120,000 miles, so most Earth-orbiting spacecraft are in the exosphere. Spacecraft that go to other planets, the sun, Lagrange points and everything that leaves Earth's orbit is in space, which is not a part of Earth's atmosphere.
What is the difference of the heliocentric model and the geocentric model?
Geocentric models had the earth as the center of the universe with the sun and all the planets orbiting it. Heliocentric models (the current accepted ones) have the sun as the center, with the earth and planets orbiting it.
What are two layers are part of the last layer of the atmosphere?
Thermosphere - extends from 80 km above the Earth Mesosphere - extends from 50 - 80 km above the Earth Stratosphere - extends from 15 - 50 above the Earth Troposphere - closest to the Earth
Is the center of the earth known as the crust?
No it is called the core which is the hottest part of the layers.
