Why were planets closer to the sun not able to retain lighter gases?

The lighter gases were blown away by the solar winds. This is why the inner planets have rocky cores and are not gaseous planets.

Which process explains why the terrestrial planets do not have hydrogen and helium in their atmospheres?
The terrestrial planets are less massive and therefore have less gravity. As a result, much of the lighter gases could escape, in the process of planet formation.
What are the two main reason why Jovian planets have much thicker atmoshperes than the Terrestrial planets?
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
What are the two major ways that the terrestrial planets and the jovian planets differ?
The four inner planets are made of rock . The outer planets are made of various gases and condenced gases. Hydrogen being prominante.
How many planets are made up of gases?
All of the planets in the solar system have at least some trace gases in their atmospheres, but the planets known as gas giants are composed of mostly gases. They are the four outermost planets, Jupiter, Saturn, Neptune, and Uranus. In contrast, the four innermost planets, Mercury, Venus, Earth, and Mars, are called the terrestrial planets and are mostly composed of solids.
Stars and planets are made from gases in a?
galaxy
Why have the Jovian planets retained their atmospheres?
Simply because the gas giants are so big that the force of gravity is sufficient to retain the light gases.
What happened to the lighter gasses once the sun formed?
Due to the Sun's strong gravity, the lighter gases would mostly stay in the Sun. The same happens - to a great extent - in the case of the larger planets.
Which process explains why the terrestrial planets do not have hydrogen and helium in their atmospheres?
The terrestrial planets are less massive and therefore have less gravity. As a result, much of the lighter gases could escape, in the process of planet formation.
What do greenhouse gases in the atmosphere absorb and retain?
Greenhouse gases in the atmosphere absorb and retain infrared radiation (heat) from the surface of the earth.
What do you call gases that retain heat within the atmosphere?
Greenhouse gases.
What are the two main reason why Jovian planets have much thicker atmoshperes than the Terrestrial planets?
While terrestrial planets are made of rock and have gases in the atmosphere, jovian planets are made almost entirly of gases. If an atmosphere is made of gases in a planet, then the atmosphere of the planets with more gases will be thicker.
Why are the planets colourful?
The gases ;)
Why the inner planets are all terrestrial?
It is my understanding that, due to their close proximity to the Sun, and the corresponding higher temperatures, lighter gases (mainly hydrogen and helium) evaporated off into space.
How many planets in are solar system are gases?
4 planets in the solar system are gases. They are Jupiter, Saturn, Uranus, and Neptune.
Is the outer planets hot?
No, the outer planets in our solar system are not hot. In fact, they are extremely cold due to their distance from the Sun. The outer planets, such as Jupiter, Saturn, Uranus, and Neptune, are made up mostly of gases and have no solid surface to absorb and retain heat.
What are the two major ways that the terrestrial planets and the jovian planets differ?
The four inner planets are made of rock . The outer planets are made of various gases and condenced gases. Hydrogen being prominante.
Why do planets have layers?
Planets have layers because of the gases that form in the solar system.
