Question

Quizplus · Accepted Answer

Regolith is the layer of broken-up or fragmented rock that is created through constant weathering processes such as erosion, abrasion or hydraulic pressure. It typically accumulates at the surface of consolidated or bedrock and can range from a few centimeters to several meters in thickness depending on the geological setting and climatic conditions. Bedrock (A) refers to the unweathered, solid rock beneath the regolith, while parent material (C) refers to the underlying geological formations that give rise to the regolith through weathering and erosion. Outcrop (D) refers to the exposure of bedrock at the Earth's surface, which may or may not be weathered or fragmented.
