Sum it all up:  

The deepest impact craters are created by __________, __________, and__________ objects.

Objects that strike at an angle will produce __________.

Impact craters can provide clues about the past.

The Principle of Superposition states:
The order of layers of geologic features found on the surface information about which features are older or younger.
Features found on top are the youngest.

If a crater is found on the floor of or overlapping the rim of another crater, it must be younger. The crater on the bottom must have been there first, making it older.

Which crater in the image is younger? (Click one)

Crater density, or the number of craters in areas of equal size, can help determine the age of the surface.

The more craters on the surface, the older that surface is.

Which surface in the image is likely to be older? (Click one)

Over time, craters can be modified by geologic processes. The more modified a crater, the older it is. Craters generally flatten and lose shape with age.

Which crater in the image below is the oldest? (Click one)

Required

Explain how scientists could determine the relative ages of two nearby planetary surfaces if Surface A has very deep craters with sharp edges and lots of ejecta, while Surface B has many shallow, worn craters and a smooth layer of lava covering parts of it.

Optional and just for fun: Play with the Asteroid Launcher website.  

Also check out some cool impact craters on Earth.
