7. Which of the following descriptions is about a sand dune?

• Found at the mouth of fast-flowing rivers, like the Mississippi. Formed by water erosion and deposition.
• Found in high mountainous areas, like the northwestern US and India. Formed by glacial weathering and erosion.
• Found in deserts and along coastlines, like the Sahara desert. Formed by wind erosion and deposition.
