what are the two major differences in the composition of the inner and outer planets?
233766
Summary. The four inner planets have slower orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have faster orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.

They are two different kinds of planets. Jupiter is a gas giant with no discernible solid surface, while Earth is a terrestrial planet. Jupiter's primary atmosphere consists of hydrogen and helium, while Earth's atmosphere is composed of a mix of oxygen and nitrogen and other chemicals.

How do the inner planets differ from the outer planets? ... Inner planets are smaller than the outer planets; gas giants have more gravity; Farther apart, inner planets have a solid surface, Inner planets are hotter, inner planets have a shorter period of revolution. Distance from the sun causes these differences.

The innermost layers of the Earth. The Earth has an outer core (liquid) and an inner core (solid). They are not chemically distinct from each other, but they are chemically distinct from the mantle. The core is mainly composed of nickel and iron.

The inner planets are made of rocky material, which has higher density; these are often known as terrestrial (earth-like) planets. The outer planets are made mostly of low density gases; these are often known as Jovian (Jupiter-like) planets.

The four outer planets—Jupiter, Saturn, Uranus, and Neptune—are all gas giants made primarily of hydrogen and helium. They have thick gaseous outer layers and liquid interiors. All of the outer planets have numerous moons, as well as planetary rings made of dust and other particles.

The earth's inner core is a solid ball of iron, nickel and other metals, while the outer core is liquid metal composed of iron and nickel as well. ... The outer core is believed to be about 2,300 kilometers (1,400 miles) thick, and is located 2,890 kilometers (1,400 miles) beneath the surface of the Earth.

The inner planets are closer to the Sun and are smaller and rockier. ... The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.

The terrestrial inner planets are composed largely of refractory minerals, such as the silicates, which form their crusts and mantles, and metals such as iron and nickel which form their cores. Three of the four inner planets (Venus, Earth and Mars) have atmospheres substantial enough to generate weather.

The terrestrial planets are rich in heavier gases and gaseous compounds, such as carbon dioxide, nitrogen, oxygen, ozone, and argon. In contrast, the gas giant atmospheres are composed mostly of hydrogen and helium.

Main Difference: The main difference between the inner core and outer core of the earth is that inner core of the earth is the innermost layer of our planet, whereas outer core is the layer that surrounds the inner core.

The generally accepted difference is one of formation; stars are said to have formed from the "top down", out of the gases in a nebula as they underwent gravitational collapse, and thus would be composed almost entirely of hydrogen and helium, while planets are said to have formed from the "bottom up", from the ...

Differences between the Inner and Outer Planets. ... The four planets closest to the Sun are known as the Inner Planets, or the Terrestrial Planets. These planets are Mercury, Earth, Venus and Mars. The four planets furthest from the Sun are known as the Outer Planets, or the Gas Giants.

All of the inner planets are solid, dense, rocky planets. The inner planets either do not have moons or have just one (Earth) or two (Mars). None of the inner planets have rings. Compared to the outer planets, the inner planets have shorter orbits around the Sun, but all the inner planets spin more slowly.

by position relative to the Sun: inner planets: Mercury, Venus, Earth and Mars. outer planets: Jupiter, Saturn, Uranus, Neptune. The asteroid belt between Mars and Jupiter forms the boundary between the inner solar system and the outer solar system.
1322604
The four inner planets, or terrestrial planets, have solid, rocky surfaces. Earth, the third planet from the Sun, is the only planet with large amounts of liquid water, and the only planet known to support life.

Because of their large mass and cooler temperature, they have a very different composition; they are mostly made of light elements with extended atmospheres in a gaseous form. Outer planets exist in much bigger systems than inner planets. All outer planets have ring systems and moons.
