[EX Q]: Process:  -Bats and other animals produce a high-pitched tone -The sound travels in waves, as sound does -The sound "bounces" off of a nearby object -The sound wave returns to the bat -The bat hears the echoed sound -Folds in the bat's ear and adaptations in the bat's brain enable it to determine the size, shape, and position of the other object via the properties of the returned sound waves -Other animals use echolocation in generally similar ways -
 Question: What is the effect of the air is in an enclosed airtight area on bats produce a high-pitched tone.?
[EX A]: none

[EX Q]: 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 -Rocks and the beach look a little different.
 Question: What is the effect of there is more calm waters on more erosion by the ocean.?
