Earth.
Earth is the planet that has gases, land masses, and large amounts of surface water. It is the only known planet to have these three characteristics in such abundance.
Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.
Jupiter is a gas giant and does not have a solid surface for nutrients as we know them to exist. It is primarily composed of hydrogen and helium with trace amounts of other gases.
Hydrogen, Helium , Methane and Deuteride are the main gases found on the planet Uranus.
Earth is the only one we know of so far :)

Mercury, the smallest planet that is also closest to the sun. It is due to these reasons that it has no atmosphere, so the surface is a near vacuum. There are trace gases about, but not in large enough amounts to call a real atmosphere.

Mars does have very small amounts of greenhouse gasses, but not enough to help warm the planet.
The planet Saturn does not have a solid surface. Saturn is almost entirely made up of gases, hydrogen and helium.
Mercury is a planet with a very thin atmosphere consisting mostly of trace amounts of gases like helium and hydrogen. However, its atmosphere is so tenuous that it is often considered to be effectively airless.
Earth is the third planet from the Sun in our solar system. It has one natural satellite, the Moon. Earth's atmosphere is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases. The planet's surface is about 71% water, mostly in the form of oceans. Earth is the only known planet to support life.
Because it has no atmosphere and thus no greenhouse gases. Greenhouse gases absorbs infrared heat emitted by an object and redistribute the energy throughout out a planet. Since there are no greenhouse gases present on Mercury, the energy absorbed by the planet can also escape the planet at a much greater rate into the vacuum that is space, thus keeping the surface temperature of the planet well below freezing
Yes, mostly carbon dioxide (96%) and a bit of nitrogen (3%), the other 1% being traces amounts of other gases.
