A vertical sequence of transgressive and regressive facies records the rise and fall of sea level.

Question

Quizplus · Accepted Answer

A transgressive sequence refers to a depositional environment that shifts vertically upwards to higher energy environments. A regressive sequence refers to a depositional environment that shifts vertically downwards to lower energy environments. These shifts are driven by changes in sea level. Therefore, a sequence of transgressive and regressive facies records the rise and fall of sea level.
