34. why is it calledredshift?\n a. because the universe turns red as it expands\n b. because galaxies turn red\n c. because the light from receding galaxies shifts toward the red end of the spectrum\n d. because red galaxies move slower\n\n35. what environmental issue is directly caused by the burning of fossil fuels?\n a. deforestation\n b. global warming\n c. acid rain\n d. ozone layer depletion\n\n36. what geological process contributes to the ongoing evolution of mountain ranges at convergent boundaries?\n a. sedimentation\n b. erosion\n c. tectonic activity\n d. glaciation
Answer
# Brief Explanations:
- For question 34, redshift is defined as the light from receding galaxies shifting towards the red - end of the spectrum.
- For question 35, burning fossil fuels releases greenhouse gases like carbon - dioxide which causes global warming.
- For question 36, at convergent boundaries, tectonic activity such as the collision of tectonic plates contributes to the evolution of mountain ranges.
# Answer:
34. C. Because the light from receding galaxies shifts toward the red end of the spectrum
35. B. Global warming
36. C. Tectonic Activity
