Model answer
What a good answer should say
- To eliminate atmospheric distortion of images
Explanation
Why this works
The cause is the presence of Earth's atmosphere, which distorts light from celestial objects. The mechanism involves atmospheric turbulence and varying density, which can blur and distort images.
The effect is that telescopes located on the ground capture less clear images, leading to inaccurate observations. Consequently, placing telescopes above the atmosphere allows for clearer, more precise astronomical observations.
