Hope it helps :)

Answer 2

Answer:

Being elastic, the entire earth does not accelerate all at once away from you when you jump. Instead, you just deform a tiny bit of earth right under your feet. If the ground you are standing on is loose and weak, such as sand or mud, then the deformation caused by jumping only travels a few meters.
