Out of the wild west during the time of colonial expansion , the native peoples would put their ears to the ground to listen for herds of bison or groups of horses in the area. Why would listening to the ground be more effective than cupping a hand around your ear while standing up on high ground?
A.the ground is denser than the air so the sound of a herd can be heard sooner through ground than through the air.
B.the ground is less dense than the air so the sound of a herd can be heard sooner through the ground than through air.
C.the ground is denser than the air so the sound of a herd can be heard through air than through ground.
D.the ground is less dense than the air so the sound of a herd can be heard sooner through the air than through the ground.
