What orbit high above earth and use instruments to gather data from the upper atmosphere?
it takes in heat from the atmosphere
Why is a telescope orbiting the earth a better location for observations than a land based telescope on top of a mountain?
because earth based telescopes have to gather light that has traveled through the atmosphere which can distort and blur the light. space based telescopes do not have to see through the atmosphere, so the the light they gather is less distorted allowing astronomers to see farther into space and get better pictures.
It extends about 75 miles. Earth's Atmosphere The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Early attempts at studying the nature of the atmosphere used clues from the weather, the beautiful multi-colored sunsets and sunrises, and the twinkling of stars. With the…
Nitrogen makes up 78% of our atmosphere and the atmosphere contains 3,346,200,000,000,000,000 cubic meters of nitrogen. Because nitrogen is a gas it tends to gather in the atmosphere rather then say, stay trapped underground. That is why its maximum concentration is in the atmosphere. It's a good thing there is so much in our atmosphere too. Without it, the earth would get pummeled by gamma rays from our sun. This could turn the earth into…
The atmosphere is the layer of gases surrounding the earth. It is composed of nitrogen, oxygen, carbon dioxide, and several other gases. Scientists have divided the atmosphere into four layers. The layer directly above the earth is called the troposhpere, and extends approximately 10 to 15km above the earth. Next is the stratosphere, followed by the mesosphere, and the thermosphere,
If the Earth were larger, there would probably be an increase in gravity. (assuming the new Earth had the same density as the old one.) A larger gravity would gather the atmosphere closer to the ground, (which might be tough on Everest climbers) and the atmosphere would be more dense, and not quite as thick. With a greater gravity, the loss of light gases would be reduced, but only by a little.
There is no sharp boundary to the atmosphere: It decreases in pressure gradually, until the amount of gas present is effectively nil. Many authorities define the end of the atmosphere at 10,000 km (6,200 mi.) above Earth's surface, although there is no significant difference in composition, temperature, or pressure between a point 8,000 km (5,000 mi.) above Earth or a point 12,000 km (7,500 mi.) above Earth.
