A geologist is studying rock layers in a river delta. The layers are buried at a shallow depth beneath sediment that the river is depositing today. Just like the sediment on top, the sediment in the rock layers was deposited by the river. How might the geologist estimate how long it took to deposit the sediment seen in the rock layers?

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
