Open Directory - Science:Earth Sciences:Geology:Geomorphology:Impact Craters

The topic of this category is existing craters on Earth, known or suspected of being formed by impact of an object from space.

For objects currently still in space, consider the category Science/Astronomy/Solar_System/Asteroids,_Comets_and_Meteors/Near_Earth_Objects.

For speculation on future impacts, consider the category Society/Future/Catastrophes/Large_Near_Earth_Object_Impacts.

Sufficiently powerful asteroid and comet impacts can change the surface of the earth, creating craters and modifying rocks and soil.
