What is it called when wind blows sand & silt against exposed rock, eventually wearing away the rock's surface?

• erosion
• abrasion
• chemical weathering
• oxidation

As a glacier moves across land it is carrying sediments. These sediments are cutting into the rock it's passing over. What processes are happening at the same time?

• The moving & the cutting are both erosion
• The moving is erosion & the cutting is weathering.
• The moving & the cutting are both weathering.
• The  moving is weathering & the cutting is deposition.
