does not involve heat
Usually near water/ involves water
sometimes contain fossils
forms from previously weathered and erroted material which may have been
igneous, sedimentary, rock metamorphic rock.

Sit on viscous (thick fluid) part and move with it
There types of plate boundaires - ANSWER1. Transform boundaries: they slide past
each other causing friction/ earthquakes
2. Divergent boundaries: two plates that pull away from each other/ creates new
crust
3. Convergent boundaries: plates push into each other/ one goes under called
