Earths atmosphere consists of 78.09% Nitrogen, 28.95% Oxygen and 1% trace elements, mainly Argon. The martian atmosphere consists of 96% Carbon Dioxide, 1.9% Nitrogen, 1.9% Argon, with oxygen present only as a trace element. Where you to inhale the martian atmosphere you would suffocate. The atmosphere on mars is also very thin, only 0.06% that of the Earth's so your blood would boil etc. The temperature is also incredibly cold ranging from - 87°C, rarely going above freezing, so humans could not function there with no form of space suit.
There are different definitions for day, but on average the Martian day is 38 minutes longer than the Earth day.
Venus is smaller than earth and its nearer to the sun so the atmosphere is hotter
Nitrogen (N2) is the most abundant gas in the Earth's atmosphere having percent volume of 78.8 compare to Oxygen 20.95 %, which falls on the second place after Nitrogen.
-- smaller -- warmer -- closer to the sun -- more dense -- greater population of living things -- fewer moons -- fewer rings -- faster orbital speed
This question does not work: atmosphere is volume, and land and sea area is just that, area. You cannot compare one to the other.Perhaps what you mean to ask is the ratio of the atmosphere's volume to the Earth's volume.The Earth's radius is around 6350 km, and the official edge of space in 100 km above sea level.The Earth's volume = πr2 = 3.14 x 6350 x 6350 = about 126,600,000 km3.The Earth's and the atmosphere's volume = πr2 = 3.14 x 6450 x 6450 = about 130,600,000 km3.The atmosphere's volume = 130,600,000 - 126,600,000 = about 4,000,000 km3.The ratio = 4,000,000 ÷ 126,600,000 = about 0.032.Or if you want that as the atmosphere as a fraction of the earth and atmosphere together: 4,000,000 ÷ 130,600,000 = about 3/100.That as a percentage is 3%.
The Martian year is about 687 Earth days.
There are different definitions for day, but on average the Martian day is 38 minutes longer than the Earth day.

Because of atmosphere
it is bigger, much bigger. The atmosphere is different because of the gases that compose it.
The hydrosphere is the body of liquid water on the earth, and the atmosphere is the body of gas around the earth.
they both have land and is hot
Venus is smaller than earth and its nearer to the sun so the atmosphere is hotter
We are adapted to breathing and living in Earth's atmosphere. A planet would need to have an atmosphere similar to that of Earth for people to find it livable.
Titan is the only satellite in the solar system to have a substantial atmosphere. Others do have very tenuous atmosphere, but Titant's atmosphere is even denser than Earth's.
it has almost doubled!
The Moon has almost no atmosphere, so that is unable to influence lunar gravity - which is about one sixth of Earth's gravity.
