Q: What is the final step of the following process: - Bats fly through an area - The bat makes sounds with their mouth or nose - The sound waves travel away from the bat - The sound waves hit objects - The sound waves bounce off the objects back towards the bat - The bat hears the sound waves echoing off the objects - The bat knows where the objects are because of where the sound echoed from

Q: 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
A: Rocks and the beach look a little different.

Q: What is the final step of the following process: - Particles in the environment interact with rocks - The particles remove small pieces of the rock each time they touch the rocks - The particles continue to hit, brush against, or grow against the rocks - The rock eventually is broken apart by this contact - The pieces of the rock are now small rocks
A:
The rock pieces are worn away into smaller and smaller pieces by the same forces
