Why are large based telescopes are built with the ability to move to oppose the movement of the earth?

Because everything in the sky appears to be moving, at a rate that takes it
across roughly the width of the full moon every two minutes ! If the telescope
were stationary and didn't follow that motion, it would be impossible to observe
any highly magnified object for more than a few seconds before it was gone, out
of the telescope's field of view, and photographic exposures of many hours would
be nothing but an astronomer's pipe dream.

Do astronomers use ground-based X-ray telescopes?
No they do not, or use gamma ray telescopes either. Not ground based.
What do astronomers use to look at planets?
Their eyes, ground-based telescopes, space telescopes.
Why should telescopes such as Hubble produce more detailed images than Earth based telescopes?
Earth based telescopes have to see through the atmosphere and all the dust it contains. space telescopes like Hubble have nothing but clearspace to see through.
Why are telescopes observations better on the moon than on earth?
Observations from Earth-based telescopes are obscured by the atmosphere.
What are the advantages of ground-based telescopes?

What are the major types of optical telescopes?
Ground-based telescopes, and space telescopes. Or: refracting telescopes (main collector is a lens), and reflecting telescopes (main collector is a mirror). Or: Home telescopes (small ones), and professional ones (larger and more expensive).

Observations from Earth-based telescopes are obscured by the atmosphere.
Do digital telescopes exist?
No, digital telescopes don't exist. The telescope which we know are optical telescopes and what NASA uses are radiation based telescopes, or something related to radioactivity. As far I know, I've never heard about digital telescopes.
Why do astronomers currently prefer orbiting telescopes over earth based telescopes?
Orbiting telescopes are located in the sky, where it is not affected by the turbulence of the atmosphere, while ground-based telescopes are located on the ground, where the atmospheric turbulence (the moving of air) is greater. This is also the reason that some telescopes are built on mountains where the atmosphere is thinner and turbulence is smaller.
What action did storm thurmond taker to oppose the civil rights movement?
He extended Civil Rights to women. That is Civil rights could not be abridged based on gender.

What makes the hubble telescope different from all the land based telescopes you have?
The Hubble telescope is different from land based telescopes in that being in space it does not suffer atmospheric distortion, thus clearer pictures.
The Hubble Space Telescope obtains higher-resolution images than most ground-based telescopes because it is?
Only because it gets no atmospheric interference, which most of the ground based telescopes do.
Can Earth-based telescopes can detect all forms of light?
No. Many frequencies of light are absorbed by the atmosphere, and so Earth-based telescopes can't detect it. That's why space telescopes such as the Hubble are so valuable; they allow us to see in frequencies that we cannot detect here on Earth.
