- D.They can observe more wavelengths of light
Model answer
What a good answer should say
- They avoid atmospheric interference and light pollution
Explanation
Why this works
The cause is the presence of the Earth's atmosphere, which can distort and absorb various wavelengths of light. The mechanism is that atmospheric conditions can scatter light and introduce noise, affecting image clarity.
The effect is that ground-based telescopes often produce less accurate data. Consequently, space telescopes can provide clearer, more reliable observations free from these interferences.
