Is abrasion primarily a physical or chemical weathering process?

💡 The Answer

• Abrasion is a process of weathering that occurs when material being transported wears away at a surface.
• The context explicitly states that the primary process of abrasion is physical weathering.
• Physical weathering involves mechanical breakdown without changing the rock's composition.
• Abrasion relies on friction from scuffing, scratching, and rubbing of materials.
