Why are the inner planets composed of heavy elements and outer planets composed of gas?

During the creation of the planets, gravitational forces pulled the heavier planets towards the center. The lighter gas filled planets by default established further orbits. It is thought that heat caused the inner planets to lose their gas composition.

How does the temperature of the inner planets compare to the temperature of the outer planets?
The inner ones are hotter and the outer ones are colder
How do the sizes of inner planets compare to the sizes of gas giants?
The sizes of inner planets are generally smaller compared to the sizes of the gas giants. The inner planets are Mercury, Venus, Earth and Mars. The gas giants are Jupiter, Saturn, Uranus and Neptune.
What is the central layer of nickel?
The inner core of the Earth is said to be composed of mainly a nickel-iron alloy also known as NIFe. Both of these elements are in their purest state in this core.
Which layer of earth is composed primarily of solid iron?
The inner core is solid and composed mostly of iron.
Identify one inner planet?
The inner planets are Mercury, Venus, Earth, and Mars. There is also the Sun
What are inner planets made of?
Heavy elements.
Most of the smaller inner planets in the solar system are composed of the heavier elements and most of the huge outer planets are composed of the lighter elements What might you conclude by that fact?
Lighter elements could not condense in areas around the sun.
Why do inner planets have similar substances?
The inner planets are mostly composed of heavier elements than the gas giants because those materials gravitated closer to the sun when the solar system was forming.
Why do the inner planets have more of the lighter elements like hydrogen and helium gas like the outer planets do?
The Sun and its planets formed form a huge cloud (disk) of dust which contained both light and heavy elements, but there were more light elements (hydrogen) than heavy. As the disk coalesced into the sun and planets the areas close to the young sun were too hot (heated by the sun) for the light elements to condense and settle onto the young inner planets which are therefore rocky, while the outer planets being further from the sun did accumulate the lighter and more volatile elements. However in the centers of the giant planets there are rocky (heavy) cores.
What are the inner planets made of?
Iron co2 silicon oxygen potassium .... and lots of other stuff hi!
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.
Why are inner planets called rock planets?
They have solid surfaces composed 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.
Why do the inner planets rotate on their axis's slower compared to that of the outer planets?
Since the inner planets are composed mainly of rocks, they are heavier, and rotate slower.
Of what substance are the inner planets mostly composed of?
Iron and Rock.
Why are the inner planets made of heavy materials?
The Inner Planets dense and rocky because they are close enough to the sun that the heat has driven off the free hydrogen and helium which forms most of the Gas Giant planets (and most of the universe). Only the heavier elements remain.
Why would the average densities of the four large outer planets be so low when compared with the average densities of the inner planets?
Because the outer planets are composed of mainly gas or ice, whereas the inner planets are composed of rock which has a higher density.
