Question

1. rivers carry tons of tiny rock fragments called sediments into the ocean. what do you think will happen to these sediments after a few million years?

Explanation:

Sediments carried to the ocean will accumulate on the ocean floor. Over millions of years, due to pressure from overlying sediments and chemical processes (cementation), these sediments will undergo lithification, forming sedimentary rocks. Also, tectonic activity might lift these rock - formed sediments above sea level over time, or they could be further eroded and transported again, but the primary process for the sediments is to become part of sedimentary rock formations through compaction and cementation.

Answer:

After a few million years, the sediments carried by rivers into the ocean will accumulate on the ocean floor. Over time, due to pressure from overlying layers and chemical cementation (lithification processes), these sediments will be compacted and cemented together to form sedimentary rocks. Additionally, tectonic forces might eventually lift these rock - formed sediments above sea level, or they could be subject to further erosion and transportation, but the key transformation is the formation of sedimentary rocks from the accumulated sediments.
