The early solar system comprised of a disk of gas which was hot near the newly formed protosun (about 2000 degrees Kelvin) and cooler at further distances. Rocky substances condensed at the higher (inner) temperatures, while icy substances condense at much lower temperatures further out (about 200 degrees Kelvin) and hydrogen and helium at lower temperatures still - just above absolute zero. So in the early stages, the inner solar system was rocky, while the planets forming in the outer regions of the solarsystem were made from (and accumulated) ice and gas. Things have pretty much remained this way since.

How are inner planets characterized?
Inner planets are characterized by their proximity to the sun and their rocky composition. They are also known as terrestrial planets as they have solid surfaces and are made up of mostly rock and metal. Inner planets include Mercury, Venus, Earth, and Mars. They are generally smaller and have shorter orbital periods compared to outer planets.
How do the inner planets differ from the outer?
The outer planets are mostly composed of gases and the inner planets are mostly made of rock, metals.
What are some differences between Pluto and solid inner planets?
One major difference is their size. Pluto is significantly smaller than the solid inner planets like Earth, Mars, Venus, and Mercury. Another difference is their composition. Inner planets are primarily composed of rock and metal, while Pluto is composed mostly of ice and rock. Additionally, inner planets have clear and defined orbits around the Sun, while Pluto's orbit is more eccentric and tilted.
Are all inner planets made of rock?
yes
The surfaces of the inner planets are mostly made of?
Rock.
Why are inner planets composed mostly of rock and metal?
The inner planets at made out of rocks because of the sun and the falling rocks.
Inner planets that are composed mainly of rock and metal are called?
Terrestrial
Why are inner planets called rock planets?
They have solid surfaces composed of rock.

What divides the planets into inner planets and outer planetss?
the 4 inner planets are rock planets and the 4 outter planets are gas planets separated by the asteroid belt
What are the inner planets made from?
The inner planets (Mercury, Venus, Earth, and Mars) are made primarily of rock.
How are inner planets similar?
All inner planets are made of rock. (Earth, Mars, Venus, and Mercury)
What is the main difference between inner planets and outer ones?
Inner planets are mostly rock and outer planets are mostly gas.

What do inner planets have that outer planets dont have?
the inner planets are hot and or warm. the outer planets have rings. they both have the asteriod belt in the middle. they both have4 planets. the inner planets are smaller, made of rock and are AWESOME!
How the inner planets are similar to each other?
The four inner planets are all made of rock or are rock based but the four outer planets are all made of gas or gas based.
