Why are telescopes placed in space above earths atmosphere?
Scintillation. Our atmosphere is in continous motion. Warm air changes the angle of EM waves passing through a little bit differently than cold air. The constant motion causes constant shifts in the waves. This is why the stars seem to twinkle. In space, there is no such distortion. Space borne telecopes see far clearer images because of this.
What is free atmosphere?
Free Atmosphere or Free Air is a part of the atmosphere that lies above the Earths frictional influence.
Does the earths atmosphere extend about 1 kilometer above its surface?
i don't know this answer sorry.
What causes the pressure of the atmosphere?
Atmospheric pressure is caused by the force of the air above the earths surface. It is measured by the point in which the air meets the atmosphere.
Why did the Hubble telescope take off into space?
The problem with ground based telescopes is that the atmosphere distorts images, The Hubble space telescope is above the atmosphere and therefore can view with much better clarity.
What is the air above the earths surface called?
The atmosphere

What layer of the earths atmosphere extends 17km above the earth?
stratosphere
What is the difference between a plane and spacecraft?
An aircraft flies in the Earths atmosphere, whereas a spaceship flies above the atmosphere.
Why are near infrared telescopes located on mountaintops and ultraviolet telescopes in Earth orbit?
The primary infrared blocker, water vapor, is mostly in the lower atmosphere and the primary ultraviolet blocker, ozone, is located high in the atmosphere, far above mountaintops.

i don't know this answer sorry.
Why is it important that the projectile in the last question be above the Earths atmosphere?
because of Air Ressistant
Why are astronomical IR telescopes deployed well above the cloud but never on the ground?
Ground based telescopes are not as effective at these observations because infrared light is largely blocked by water in Earth's atmosphere.
Why have scientists put ultraviolet infraredgamma-ray and X ray telescopes in space?
they did it to get more detailed pictures of space

What is the lowest layer of Earths atmosphere the one directly above the ground called?
The Troposphere. M. West
