Final answer:
Frost shattering is a geological process also known as frost wedging, where water freezes in rock cracks and expands, causing the rock to break apart.
Step-by-step explanation:
Frost shattering is also referred to as frost wedging. This geological phenomenon occurs when water seeps into cracks in rock and freezes. As the water freezes and turns to ice, it expands by about 9%, which can exert tremendous pressure on the surrounding rock - enough to cause the rock to fracture and break apart. Over time, this process can significantly alter the landscape, as can be seen in places like Bryce Canyon, Utah, where frost wedging is a key force shaping the unique rock formations. Therefore, the correct answer to the question 'Frost shattering is also called frost ________.' is E) wedging.
