Final answer:
Wave-cut benches can indeed become terraces when there is a relative rise in the land surface compared to the sea level, a process that is true due to tectonic uplift or sea level changes.
Step-by-step explanation:
Wave-cut benches become terraces when the land surface rises relative to the sea level. This statement is true. A wave-cut bench is formed by wave erosion along a coastline at the foot of cliffs or steep slopes. Over time, with tectonic uplift or a drop in sea level (regression), these benches can be elevated above the sea level, forming a terrace. Conversely, if sea level were to rise (transgression), sediment would be deposited closer towards the coastline, creating an onlapping pattern as reflected in Walther's Law.
The changes in sedimentary environments also relate to the tectonic setting, as seen in the Recôncavo Basin. Moreover, adaptations like terrace farming in the Andean region are examples of human intervention to create arable land on sloped terrains, which are not related to the wave-cut benches becoming terraces.
