Weathered particles are eroded and then deposited when the momentum of the river slows down.So a delta has to start with weathered particles and then the particles have to be eroded and then they are deposited.aking the world better, one answer at a time.

INTRODUCTION: Inverted papilloma (Schneiderian papilloma) is a primarily benign lesion that occurs in the nasal cavity and paranasal sinuses. Clinical problems include a tendency towards local destruction, recurrence and malignant transformation into squamous cell carcinoma.
Kramer and Som classified SPs as true nasal neoplasms and described them as true papillomas, distinguishing them from inflammatory nasal polyps.Ringertz was the first to identify the tendency of SPs to invert into the underlying connective tissue stroma, which differs from other types of papillomas.
