What did oparins hypothesis suggest that early earth atmosphere lack?
oxygen
How does the lack of an atmosphere in space affect the reflection of starlight?
Because it wants to...and nobody cares. :)
Why does earth have atmosphere whereas other don't?
Earth has an atmosphere due to its gravity and magnetosphere. Other planets do have atmospheres (Venus, Mars, Jupiter, Saturn, Uranus, etc.) and even some moons have been shown to have them. Some planets lose their atmospheres or don't have them at all due to either their small size preventing them from holding onto the gases required to form an atmosphere, or their lack of geological activity (a molten core like earth possesses) meaning there is no magnetosphere (a magnetic field surrounding the planet that redirects particles from the sun around the planet) which causes the atmosphere to be eroded away over time by solar wind (a constant stream of charged particles emitted by the sun) and lost into space. Our magnetosphere and the interaction with particles from the sun and those in the upper atmosphere are the cause of the Aurora Borealis. This is a very basic explanation, for more information on the topic look to wikipedia.
Why troposphere is densest part of the atmosphere?
gravity helps pull down the layers of the atmosphere and the upper atmosphere is further away so its going to have less of a pull on it there for being less dense then the closest atmosphere. hoped that helped.
What is composed of hot dry air?
Oxygen and carbon dioxide mix match to form hot dry air.
What is the relationship between the moon and surface gravity lack of atmosphere and temperature range?
The Moon's gravity causes the lack of atmosphere (any possible atmosphere evaporates out into space in a fairly short time); and the lack of atmosphere causes the extreme temperatures.
What is the relationship between the moon surface gravity lack of atmosphere and temperature range?
The Moon's gravity causes the lack of atmosphere (any possible atmosphere evaporates out into space in a fairly short time); and the lack of atmosphere causes the extreme temperatures.
What limitation of a refracting telescope could be 'overcome by placing the telescope in space?
If the telescope were placed in space (like hubble) the images would be greatly improved due to the lack of both atmosphere and ambient light, such as streetlights. The lack of atmosphere means that the light from distant objects need not travel through turbulent gases found in the atmosphere. this would eliminate the 'twinkling' of stars, and the lack of ambient light would result in much greater detail in the image.

Why is Mars the only planet humans stay alive on?
Im pretty sure if i put you on Mars you'd die pretty quick, mostly due to the lack of substantial atmosphere allowing huge temperature swings. Also noxious gases (or lack thereof)
Why do most planets lack seas and ocean?
the lack of oxygen, and h2o in the atmosphere.
What is the most distinctive property of noble gases is that they are called what?
noble gases are also called inert gases due to their lack of reactivity
Is helium poisenous?
No however the lack of oxygen is deadly. It is unlikely that you will hurt yourself sucking the helium out of balloons, as long as you breathe oxygen in between breaths of helium. There is a small percentage of helium (.0005%) in the earths atmosphere.
What gas did early atmosphere lack?
Oxygen
Why lack of atmosphere around the moon?
The moon's gravity is too weak to hold on to an atmosphere.
What are some results of the Moon's thin atmosphere?
Our moons lack of atmosphere means that it is a vacuum at the surface, it's like being in space. The lack of atmosphere means that meteors are able to hit the moon without being burnt up by frictional forces. The lack of atmosphere also means that there is no weather, wind or rain.
