Why do temperatures on the surface of Mars vary between day and night more than they do on the Earth's surface?
Because Mars has much less of an atmosphere to hold in the gases/heat. It also does not have any vegetation, which helps hold heat near the ground. This lower atmosphere also means that water cannot be sustained in a liquid state on Mars. So without massive planetary change, we could never inhabit it.
What holds the atmosphere to the earth?
The earths gravity. The more mass a body has, the more gravity, The Earth has enough mass to hold an atmosphere. The Moon, on the other hand, is not massive enough, and so does not have a high enough gravity, which prevents it from holding an atmosphere.
Why is the water on the moon frozen?
The moon doesn't have the kind of atmosphere that can hold heat like Earth. Therefor, it is too cold for water.
List two reasons why the moon's surface has high temperatures?
he extreme temperatures on the moon are a result of the moon having no atmosphere. It gets up to 100 deg Celsius because there is no atmosphere to block some of the sun, and gets down to -173 C because there's no atmosphere to hold heat in at night.
What might surface temperatures be like on a planet with no atmosphere?
It largely depends on how close to the parent star (or sun) the planet is, but planets with no atmosphere will tend to have rather extreme temperatures. They will go from hot days to cold nights more easily as there would be no atmosphere to hold the heat from the sun, so they'll have a larger temperature range throughout the day/night cycle.
What happens to the infrared radiation that earth emit to the atmosphere?
Much of it is captured by the greenhouse gases, which hold the heat and prevent it escaping into space. As we add more and more greenhouse gases, they are able to hold more heat. This is how we are causing global warming.
The process by which gases hold heat in the atmosphere is called the what?
The Greenhouse Effect. It happens when Greenhouse Gases (CO2) thicken the atmosphere and trap heat.
What is The process by which gases in the atmosphere hold heat?
I think that you are talking about the greenhouse effect.
Why does the earth remain warm after sunset?
The surface of the earth holds heat, and the greenhouse gases in the atmosphere hold heat all through the night. If the earth had no atmosphere, then at night all the heat would escape out to space and the earth would be freezing.
Why doesn't mercury's serface hold heat as it rotates from fasing towards the sun to facing away from it?
Mercury has no atmosphere. That is why Mercury doesn't hold any heat.
When gases in the atmosphere form a blanket around the earth to hold heat in?
not liquids or solids?
How do greenhouse gases trap heat in earths atmosphere?
Greenhouse gases aren't trapping heat it but letting more in. The Earth's atmosphere blocks out most of the suns heat and harmful rays. With the gases polluting the world, the atmosphere is slowly weakening, letting more and more heat through.
Why is venus is hotter than mercury even thow mercury is nearest to the sun?
Because mercury doesn't have and atmosphere it isn't able to hold on to the heat from the Sun. So at night Mercury gets VERY cold. Venus has a very thick atmosphere and it is able to hold on to its heat.Mercury:all the heat escapes because it doesn't have a thick atmosphereVenus:has a thick atmosphere and it is able to hold no to the heat unlike mercury
How is the atmosphere related to global warming?
Greenhouse gases in the atmosphere catch and hold the sun's heat. These gases are building up as we burn fossil fuels. The more gas there is the warmer it gets. This is causing global warming.
Which planet closest to the sun and why isn't it the hottest planet?
Mercury is the closest planet to the sun, but is only the second hottest planet after Venus. Venus gets hotter as the thick carbon dioxide atmosphere holds the heat more effectively, while Mercury has no atmosphere to hold the heat.
Would Venus weigh more with the heat and gas in the atmosphere?
The heat would make no difference, but the atmosphere would increase the weight.
Why does the temperature drop a lot in other planets at night?
The temperature does not drop drastically on all planets, only planets with a thin atmosphere, such as Mars or Mercury. It is because the thick atmosphere traps the heat, and clouds are a bonus, like on Venus, because they trap much more heat than just a thick atmosphere. On a planet like Mars, which has a very thin atmosphere, it cannot hold on to very much heat in the night side, and a planet like Mercury cannot trap any heat and cannot be shielded from the heat for lack of a real atmosphere. That is the basic idea. =)
