Will mark a scientist observes the ocean tides moving large amounts of sand away from the beach. this is evidence for which type of natural process? a) physical weathering b) chemical weathering c) erosion d) deposition

erosion because it is the breaking down of the earth over time by wind or water

Erosion

Explanation: because in the 2.03 it says something about breaking down something, but I'm pretty sure that's the answer.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.
