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.
Note the following: Bowel obstruction: This is associated with up to 30% of benign small bowel tumors, and these tumors remain the leading cause of intussusception in adults. Volvulus: Volvulus from serosal ependymal lesions has also been reported. Three types of small bowel adenomas have been described: adenomatous polyps, Brunner gland adenomas, and villous adenomas. 2  In general, they may develop as single or multiple lesions, both sessile and pedunculated.
