Lava flows on the Moon and Mercury created large, smooth plains. We don't see similar features on Earth because
a. Earth has less lava.
b. Earth had fewer large impacts in the past.
c. Earth has plate tectonics that recycle the surface.
d. Earth is large compared to the size of these plains, so they are not as noticeable.
e. Earth's rotation rate is much faster than that of either of these other worlds.
