Inside walls are still terraces, although they are rounded due to erosion.   The name is from Bartholomaeus Pitiscus (also Barthelemy, Ba…rtholomeo, 24.08.1561-02.07.1613) which was a trigonometrist, astronomer and teolog.He invented the first trigonometry.   Read more: http://lupuvictor.blogspot.ro/2011/03/hommel-and-pitiscus-craters.html

The Moon is much less geologically active than Earth. Unlike Earth’s crust, whose multiple tectonic plates overlaps and collides and gave rise to mountain areas or destroyed bottom seas, the Moon’s crust is a rigid single plate. A series of Moon features results from the deformation of the crust, which include compression (shortening) and tension (extension). Tectonic features are well illustrated around Humorum and Serenitatis basins.
