Craters
Impact craters generally have a rim with ejecta around them, in contrast volcanic craters usually do not have a rim or ejecta deposits. As craters get larger (greater than 10 km in diameter) they usually have a central peak. The peak is caused by a rebound of the crater floor following the impact. Sometimes craters will display layers. Craters can show us what lies deep under the surface.

Famous quotes containing the word craters:
“Listen.
We must all stop dying in the little ways,
in the craters of hate,
in the potholes of indifference....”
