5 Tatanan

5.1 tatanan

gneiss punika bahan dhuwur metamorphic rock IE wis ngalami luwih Suhu lan tekanan saka Schist. iku kawangun dening metamorfosis saka wangun gneiss saka rock vulkanik, krikel utawa granitie.

nalika lahar dirilis saka gunung, iku diwiwiti saka cooling cepet banget kang freezes mekanisme saka crystallization. asil punika kaca vulkanik karo susunan Gamelan seragam.
