Earth
These pictures show craters at different places on the Earth's surface.

Like other planets, the surface of the Earth has many
craters. Barringer Meteor Crater (right image), located in Arizona, is 1.2
km across, and is 49,000 years old. The twin impact craters seen
in the left image are Clearwater East and West craters, located in
Quebec, Canada. They were formed at the same time by two separate but
probably related meteorite impacts. These two craters, which are much
older than the Barringer crater, appear much more worn away or eroded
than the younger crater.

Mars
These pictures show examples of craters on the surface of Mars.
The picture at the left shows the Sinus Sabaus and Deucalionis Regio
region of Mars, and was obtained by Mariner 6 in 1969.

There are many craters on the surface of Mars. The
image at the
left (best seen at full size), taken by Mariner 6 in 1969, shows many
craters in the Sinus
Sabaus and Deucalionis Regio region of Mars. The crater at the lower
right of this image is Flaugergues and the double crater to the lower
left is Wislicenus. In the full size image, you can see craters within
craters, overlapping craters, and craters with raised central peaks. The
image at the right shows an eroded crater and sand dunes near the south
pole of Mars. Craters in this region of Mars are being
erased by the action of sand on the Martian surface. There are even sand
dunes within the crater.
