Both Earth and Mercury have atmospheres, but they are very different. Earth's atmosphere is dense and rich in oxygen, suitable for supporting life. Mercury has a very thin exosphere composed mainly of oxygen, sodium, hydrogen, and helium, which is not conducive to sustaining life.
What else can I help you with?
Why does the Earth have an atmosphere?
The Earth has an atmosphere to protect life by providing oxygen for living organisms to breathe and to regulate the planet's temperature by trapping heat from the sun. It also shields the Earth from harmful radiation and meteoroids.
Is Mercury or earth hotter?
When it is night on Mercury, it's colder than earth at any given time,but during the day,obviously,there is no comparison,the earth is much colder. BY THE WAY:this is coming from a 13 year old ;) but one that knows her sh*t.
Torricelli invented a device for measuring air pressure called a(n)?
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
What planet has the weakest greenhouse effect?
Mars has a weak greenhouse effect compared to Earth. Its thin atmosphere is primarily composed of carbon dioxide, which is not as effective at trapping heat as Earth's predominantly nitrogen and oxygen atmosphere.
How are earth and moon alike different?
They are round in shape, also they have crater's. However the moon has no water or life, but Earth does. Earth is a planet and the moon is not.Also how the moon is different is it is 1/6th of Earths gravitational pull.
How are earth and Mars are alike and different?
earth and mars are like and different because they have a atmosphere and gravity
Is Mercury different from earth?
Mercury can not support life, Mercury does not have an atmosphere, no seasons, shorter orbit around the sun, etc.
How are earth's moon and mercury's moons alike?
Mercury does not have a moon.
How are mercury and earth alike?
both planets
How are Earth's moon and mercury alike?
The Earth's moon and Mercury are alike in that they are both rocky and airless. They are also both devoid of life and both have craters and plains.
Does mercury have an atmosphere that is very similar to earth's atmosphere?
mercury has no atmosphere which means it is nothing like earths.
Can you breathe on planet mercury?
No. Mercury essentially has no atmosphere. Earth is the only planet with an atmosphere that humans can breathe.
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.
Does mercury have a thick atmosphere compared to earth?
No, it has hardly any atmosphere.
What is the Mercurys atmosphere compared to earth?
Mercury's atmosphere is extremely thin compared to Earth's. It is composed mostly of oxygen, sodium, hydrogen, helium, and potassium, but its overall density is about 100 trillion times less than Earth's atmosphere. Mercury's weak gravity isn't strong enough to retain a thick atmosphere like Earth's.
What two planets are most alike?
Venus and Earth are the two planets that are most alike in terms of size and composition. They are similar in mass, density, and have a similar rocky composition. However, Venus has a harsh environment with extreme temperatures and a thick, toxic atmosphere, unlike Earth.
Why do planets like mercury have many more crater holes then earth?
Earth has an atmosphere unlike Mercury. Since Earth has an atmosphere, the meteriors burn up before they hit the ground. Mercury has little to no atmosphere so the meteriors are free to hit the ground and make craters.
