Answer:
If sea level vary just as a function the doesn't depend on the regional erosion/ uplift then the sea level changes are determined just as a module of 10 is multiplyed by 100, 1000, 10 000 for the next 1000, 1000000, 10 000000 years
If not then we have to have the coordinates of the interconnected variations
Ans: waterfalls are most common where hanging valleys occur. Such valleys generally form when glacier ice deeply erodes a main or trunk valley, leaving tributary valleys literally hanging far above the main valley floor. After the glaciers have melted and withdrawn, streams from such tributary valleys must fall in order
