Here's the correct matching of each landform with its definition based on elevation and characteristics:
- Mountains - rise at least 2,000 feet above sea level with steep sides
- Plateaus - broad, flat highlands with canyons cutting through them
- Mesa - Small, flat-topped landform with steep sides
- Buttes - even smaller landforms similar to mesas
- Hill - between 500 and 2,000 feet high with rounded tops
