Explanation / Answer

4)- option b

the depositional environment at the time here was in the volcanic arc mountain range.

5)- option a

which is at subduction zone the downgoing plate is composed of oceanic lithosphere.

6) - option b

which is the Laramide orogeny, was the major event that was occuring at the same time of the ancestral mountain upliftment. Infact, it was one of thecause for the uplifment of the ancestral mountain.

7)- option b

which is plants, mammals,arthopods. Microorganism are thought to have paved the way for inception of land plants. The earliest complex land plants date back to around 850 million years.
