A heavy rain started coming down, blanketing the stadium and flooding the concrete decks. Large rivers watered the land, occasionally flooding and blanketing the region with new sediment. On January 29, it snowed again in Haifa, blanketing most of the city in white. The calcareous ooze blanketing Nazca Ridge is completely subducted. The most common gas used in blanketing is nitrogen. Char bed and water can coexist as steam blanketing reduces heat transfer. Tank blanketing is also used to keep contaminants out of a storage space. Selectivity also provides some immunity to blanketing interference.
