Please check my homework: list what happened first to last. I'd say V-C-O-M-X-K-E-B-S-Z-J-G-L-F-T-D-A-P-H-N-R but I'm not sure about the last few letters and when T happened- it is a geologic structure, fault I think but it seems a bit strange to be marked lightly. I'll comment what the letters mean
