Final answer:
Ice wedging and abrasion are both processes involved in the weathering and erosion of rocks. Ice wedging occurs when water seeps into cracks and crevices in rocks, freezes, and expands, causing the rock to crack or break apart. Abrasion is the mechanical weathering process in which rocks and sediments are worn down and eroded by the frictional action of moving water, wind, or ice.
Step-by-step explanation:
Ice wedging and abrasion are both processes involved in the weathering and erosion of rocks.
Ice wedging occurs when water seeps into cracks and crevices in rocks, freezes, and expands, causing the rock to crack or break apart. This process is commonly seen in areas with freezing and thawing cycles, such as mountainous regions.
Abrasion is the mechanical weathering process in which rocks and sediments are worn down and eroded by the frictional action of moving water, wind, or ice. It involves the scraping and grinding of rock surfaces by the abrasive forces of these agents, leading to the formation of smoother and rounded features.
