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.
A virus, known as the papillomavirus, causes the growth. The general appearance is wart-like, raised, with the central surface having an open pore if the wart is inverted. In dogs, the warts are most commonly presented in a raised manner; however, inverted warts are not uncommon. The pigmented appearance normally presents as a rough surface that is flat in appearance and black in colour. There are instances where the papillomatosis can progress, causing common forms of skin cancer.
