How much more mass does mercury have than earth?
Mercury does not weigh anything more than earth
Why does the Earth have an atmosphere while other planets do not?
AnswerThe truth is, the other planets DO have atmospheres.Planets other than Earth have gases surrounding the planet just like we do here. However, the types and/or quantities of gases in the atmospheres of other planets are simply not capable of supporting life like Earth is for one reason or another.Venus, for example, has an atmosphere extremely rich in greenhouse gases such as Carbon Dioxide. Because of this, Venus is a VERY hot planet from all the solar radiation that is constantly beaming onto the planet with no way to escape.Venus is not hot though find out more on wikipedia
Why does the moon have more surface craters than the Earth does?
I'm no expert but id guess that earth (being a larger target) has been hit more then mercury. (here is where the guessing ends) but mercury is devoid of water Ware as earth has lots. their was once a time where earth was covered with impact craters. but over rain eroded them away. mercury has no rain so the craters will stay their for millions of years
Where are the alkali and alkaline earth metals located on the periodic table?
Alkali metals: Group 1 in the periodic table Alkaline earth metals: Group 2 Halogens: Group 17 Noble Gases: Group 18 You can easily find them if you look at a periodic table.
Is earth the fastest revolving planet?
Yes, Earth does spin faster than Mercury.For more details, visit this NASA site:http:/www.nasa.gov/worldbook/mercury_worldbook.html
What is the current situation of the earth's atmosphere?
Well in terms of Global Warming, the burning of fossil fuels (gas for cars is one) releases more greenhouse gases, which mean there are more greenhouse gases in the atmosphere. These gases reflect sunlight BACK towards earth, keeping it warm. So the more greenhouse gases means the earth is warmer.
Is the greenhouse effect more pronounced for florists or earths surface?
The greenhouse effect is more pronounced for the earth's surface. Heat rising from the surface is trapped by greenhouse gases. These warm gases heat the air around them as well, also, as the earth' surface again.
How is the gardeners greenhouse a miniature version of the greenhouse effect?
The greenhouse effect is called that becouse the earth naturally acts like a greenhouse but with the gases (like CO2) going up into the air, the barrier around the earth that acts like a greenhouse, makes the barrier stronger and that makes the earth get more warmer. So...The more greenhouse gases we produce the warmer the earths temperture would be

What do greenhouses gases trap?
Greenhouse gases trap infrared heat (from the sun) rising from the surface of the earth. More greenhouse gases trap more heat, and this is the situation now. Increasing levels of carbon dioxide (CO2) in particular are trapping more heat and causing a global warming.
How does the increase in greenhouse gases support the theory of global warming?
Part of the theory of global warming is that greenhouse gases capture the earth's heat. If more greenhouse gases are added to the atmosphere then more heat will be retained.We can measure that levels of greenhouse gases have increased, and we can measure that temperatures have risen. These measurements thus support the theory of global warming.
What would happen if gases absorbs visible light?
Earth's atmosphere does have greenhouse gases. These gases absorb some of the infrared radiation emitted by Earth's surface. If it did not, Earth would grow warmer and warmer as it absorbed more and more solar radiation. Greenhouse gas molecules absorb and emit infrared radiation.
Why should humans care about the increase in greenhouse gases?
If we do not care about the increase in greenhouse gases, the climate of the Earth shall increase in temperature and then we will all be bunz-pasted. And no more doing it for babies.
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.
What is the purpose of reducing greenhouse gases?
If we don't reduce the levels of greenhouse gases in the atmosphere the earth will get warmer and warmer. Greenhouse gases trap the sun's heat. Whenever we burn fossil fuels, that is, for transport or to produce electricity, we are adding more and more carbon dioxide into the atmosphere. This is what is causing global warming.
How does the greenhouse effect affect the air temperature?
The greenhouse effect keeps the air and earth warm enough for life.The sun's energy warms the earth.Infrared heat rises from the surface of the earth into the atmosphere where it is trapped by greenhouse gases causing the greenhouse effect.The warm greenhouse gases in turn warm the surrounding atmosphere, and some of this heat goes back down to earth, where it adds more warmth to the earth's surface.
Having more greenhouse gases in the atmosphere will do to the average temperatures in the atmosphere and why?
Green house gases will keep more of the heat that enters the earth. It will raise the temperature
