Why some planets moons have atmospheres and others don't?
All of the planets except for Mercury have substantial atmospheres. Mercury is the least massive of the planets and has the weakest gravity, which makes it hard to hold on to gasses. It is also the closest planet to the sun, and the intense heat will tend to drive away any gasses that would collect around the planet. The moons of the solar system all have weaker gravity than Mercury does, so most are unable to hold onto an atmosphere. Titan, the largest moon of Saturn, is the only moon in the solar system to have a substantial atmosphere. While it has weaker gravity than Mercury it is much farther from the sun and much colder, which makes it harder for gasses to escape. Other large moons, even cold ones may lack atmosphere for a few reasons that could have to do with the compositions of the moons or events in the past that may have driven an atmosphere away.
What is the correct unit for pressure?
Pascals, KiloPascals, inches of mercury (inHg), millimeters of mercury (mmHg), and pounds per square inch (PSI) are several common units of pressure. Some others are: Bar, Torr, Atmospheres.
What the atmospheric of mercury?
Mercury has no significant atmosphere.
Why are the temperatures on each of the others terrestrial planets more extreme than the temperatures on earth?
On Mercury & Mars there is negligible atmosphere thus extremes in temperature.On Venus its hot - constantly. Because the atmosphere is much thicker.
What is the planet Mercury main gases?
Carbon dioxide 95.32%Nitrogen 2.7%Argon 1.6%Oxygen 0.13%Carbon monoxide 0.07%Water vapor 0.03%Nitric oxide .0013%Trace gases(including krypton and methane among others)Improved answer : Mercury has no significant atmosphere, but hasMINUTE traces of some gases.
How are the compositions of the inner planet's atmospheres alike?
Mercury doesn't have an atmosphere of any significance. Earth's atmosphere is nothing like the others. That leaves Mars and Venus. They do have similar atmospheres because they both have about 95% carbon dioxide. However the atmosphere of Mars is much thinner than Earth's whereas Venus has a much thicker atmosphere than Earth's.
What can you predict about mercury's atmosphere?
Mercury's atmosphere comprises the following:Oxygen (42%),Sodium (29%),Hydrogen (22%),Helium (6%).others (traces).
How does Titans atmosphere compare with the atmospheres of other satellite in the solar system?
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.

What the atmospheric of mercury?
Mercury has no significant atmosphere.
True or false all of the moons in your solar system are rocky worlds with no atmospheres?
False. Some moons like Titan of Saturn have a thick atmosphere; others are not rocky, being mainly balls of ice.
Why are the temperatures on each of the others terrestrial planets more extreme than the temperatures on earth?
On Mercury & Mars there is negligible atmosphere thus extremes in temperature.On Venus its hot - constantly. Because the atmosphere is much thicker.
Are all metals in solid state at room temperature?
no. Mercury is a liquid at room temperature under 1 atmosphere. And hydrogen, technically, is also a metal.
Are Mercury luxury cars?
yes Mercury luxury are cars but not as fast as others
Why mercury thermometer is accurate than others?
Because mercury is very fast dissolving metal
Is it true mercury doesnt have enough gravity to have an atmosphere?
Mercury does not have what we would call an atmosphere. It is very, very thin , a collection of a few atoms per cubic meter, some being ionized from the surface. It is less than a trillionth of Earth's.
