Problem: Given the question: What is the final step of the following process: - Water from the ocean washes onto beaches in waves - The waves contain sediment from the ocean - The water and particles in it hit rocks and sand on the beach - The wind and current sometimes push the water and particles harder - Tiny parts of the rocks on the shore come off the larger rocks - The waves pick up sand and small rocks from the beach - The waves go back out into the ocean - The waves carry the new particles with them
++++++++++++++++++++++++++++++++
The answer is:
Rocks and the beach look a little different.
