It was from a giant cloud of gas and dust, called a nebula that collapsed forming our solar system. Slowly, gravity began to pull the solar nebula together, which began to spin faster and faster until it flattened into a disk. Gravity pulled most of the gas into the center of the disk, where nuclear fusion began. This created our sun.
Meanwhile, in outer parts of the disk, gas and dust particles collided and stuck together. Eventually the bigger pieces planetesimals, combined to form our eight planets. Planets that stuck together in the inner solar system were small terrestrial planets (rocky). Planets that stuck together in the outer solar system were large gas and ice giants.

∙ 14y agothey form because when rock and gas mixes, the planets starts to make its shape and then it turns into a gas planet

We don't actually know how gas giants are formed. First of all the term gas giant is misleading. The term gas giant refers to a planet which is predominantly hydrogen and helium.

What causes clouds to form individual planets over time?
gas
For what reason did the inner planets not collect gas like the gas giants did?
The inner planets did not collect gas like the gas giants did because of their closeness to the Sun. The high temperatures allow for rocky, solid surfaces to form.
How many gas planets are there?
In our Solar System, there a four gas planets. To be factually correct, there are only 2 gas planets - Jupiter and Saturn. and 2 ice planets - Uranus and Neptune. Combined, they a colloquially known as the Gas giants or Jovian planets.
How the sizes of the inner planets compare to the sizes of the gas giant planets?
The inner planets are smaller than the gas giant (outer) planets.
Which planets are gas planets?
The Gas Giant planets are: Jupiter, Saturn, Uranus, and Neptune.
What type of stars form planets?
None Stars are gas Planets are solid
Can condense and become concentrated enough to form a star and possibly planets?
A gas cloud. It must contain dust to form planets. (And lots of hydrogen to form a star.)
What causes clouds to form individual planets over time?
gas
Will there ever be more planets?
In the words of my physics teacher 'Not in your lifetime!' Planets form from a disk of dust and gas when the star is just a proto-star. Planets cannot form after the star has been formed.
For what reason did the inner planets not collect gas like the gas giants did?
The inner planets did not collect gas like the gas giants did because of their closeness to the Sun. The high temperatures allow for rocky, solid surfaces to form.
What caused the dust cloud to form individual planets over time?
Gas
What causes dust clouds to form individual planets over time?
gas
Why can't gas leave the gas planets?
The gas of the gas planets is kept in place by gravity.
Are the gas planets bigger or smaller than the rocky planets?
the gas planets are bigger than the rocky planets
Can gas planets have craters?
No. Gas planets do not have solid surfaces.
Which planets are gas planets and why are they called that?
Gas planets are the planets formed with gas - eg earth has a crust so it is a rock planet. But Jupiter is a planet composed of gas so it is a gas planet. Nothing solid at all. The Gas Planets are: Jupiter Saturn Uranus Neptune
Which planets are terrstrial which planets are gas planets?
Terrestrial:Mars Gas: Saturn, Jupiter, Uranus and Neptune
