| What is the difference between a volcano and an impact crater? |
|
Definition
Volcanoes have lava flow, a round, flattened rim, a smooth crater floor and a bullseye ridge pattern.
Impact craters have a central peak and sharp edges. |

| Are there any small craters on Venus? |
|
Definition
There are no
small
craters on Venus.
Meteorites
are

destroyed
in
the atmosphere.
Crater
clusters
exist
on the the surface of Venus. Larger
meteorites
break
up
before
impact to form these clusters.
Also, a
lack
of
large
craters
indicates
resurfaced
area. |

| What is the most geologically active moon in the solar system? |
|
Definition
| IO. Io is the innermost Galilean moon. It is bigger than our moon, and has over 400 volcanoes. The volcanism is due to Jupiter's pull, not due to tectonics. The volcanoes spew out sulfur and oxygen, and these elements create a plasma torus. |
