Mercury is the only planet (and inner planet) without an atmosphere - due to its small size. Mars has an atmosphere, but it is a thin one, mainly of carbon dioxide.
Jovian planets do not have a solid surface, therefore their atmospheres are thick all the say to where their surface would be. Their atmospheres have more gasses than those surrounding terrestrial planets.
Jovian planets are less dense when they Are compared to terrestrial planets because they are Mostly composed of hydrogen gas.
The terrestrial planets in order from the thickest to thinnest atmospheres Venus, Earth, Mars, and Mercury. Since the gas giants are almost entirely made of gas, it is difficult to determine where the atmospheres end.
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.
The masses of the gas giants are greater, which would make them larger, and their gravity can hold more massive atmospheres. Due to limits on the compressibility of atmospheric gases, these atmospheres are very deep. The lower solar heating farther from the Sun also plays a role in allowing these planets to maintain a high percentage of their lighter gases (hydrogen, helium) than the inner planets. So, even without their atmospheres, the cores of gas giants would have greater diameters than the terrestrial planets. They are simply bigger planets.

The four Jovian planets in our solar system are Jupiter, Saturn, Uranus and Neptune. The four terrestrial planets are Earth, Venus, Mars and Mercury. The difference between the Jovian planets and the terrestrial planets is that Jovian planets are enormous and made of gasses and ices while terrestrial planets are relatively small and made of rocks and metals. Other differences are that terrestrial planets have high densities, rotate slowly, have no moons or magnetic fields and have thin atmospheres (Earth is an exception because it has a moon and a magnetic field), while Jovian planets have low densities, rotate rapidly, have many moons and a magnetic field and have thick atmospheres.
They are different because terrestrial planets is any of Earth like planets including: Mercury, Venus, Mars, and Earth. However jovian planets are the Jupiter like planets including: Jupiter, Saturn, Uranus, and Neptune
No. As the name gas giant implies, these planets are made largely of gas. They have extremely thick atmospheres.
The masses of the gas giants are greater, which would make them larger, and their gravity can hold more massive atmospheres. Due to limits on the compressibility of atmospheric gases, these atmospheres are very deep. The lower solar heating farther from the Sun also plays a role in allowing these planets to maintain a high percentage of their lighter gases (hydrogen, helium) than the inner planets.

Yes. all the terrestrial planets have atmospheres. however, in the same area that there are 10 Billion Billion Atoms in earth's atmosphere, (about 1 cubic in) there are about 10 million atoms in mercury's. maercury has almost no atmosphere, and we don't even know what it is, but both mars and Venus's atmospheres are 95 % CO2, but venus's atmosphere is thick, even thicker than earth's, but mars's is thinner than earths. all the terrestrial planets have some kind of atmosphere.
The gas giants and the terrestrial planets initially formed in similar ways, however, the powerful solar wind of the young sun stripped away the first atmospheres of the inner planets. The outer planets were less affected by this and so retained their thick atmospheres of hydrogen and helium. Today, the outer planets recieve much less heat from the sun than do the inner planets, allowing various ices to form.
The greatest difference is in their size. Gas giants are large but have a very low average density (much of their size includes their atmospheres). From a physical standpoint, terrestrial (rocky) planets have a solid exterior surface. Jovian (gas giant) planets instead exhibit a smooth range of increasing density, and do not have the abrupt change to solidity that terrestrial planets exhibit.
