During the last glacial maximum, where was the highest rate of deposition of ice

Question

During the last glacial maximum, where was the highest rate of deposition of ice-rafted debris in the North Atlantic Ocean? A. Near the Arctic Circle B. Near their sources areas in Greenland and Canada C. Near their sources areas in Scandinavia and Iceland D. Where the icebergs first encountered warm water, at 45-50*N E. Where the icebergs first encountered warm water, at 5-15* N During the last glacial maximum, where was the highest rate of deposition of ice-rafted debris in the North Atlantic Ocean? A. Near the Arctic Circle B. Near their sources areas in Greenland and Canada C. Near their sources areas in Scandinavia and Iceland D. Where the icebergs first encountered warm water, at 45-50*N E. Where the icebergs first encountered warm water, at 5-15* N A. Near the Arctic Circle B. Near their sources areas in Greenland and Canada C. Near their sources areas in Scandinavia and Iceland D. Where the icebergs first encountered warm water, at 45-50*N E. Where the icebergs first encountered warm water, at 5-15* N

Explanation / Answer

The highest rates of deposition from north atlantic ocean where the icebergs first encountered warm water, at 45-50*N because of the small ice rafting episodes at volcanic rock and red sandstone and the larger ice rafting episodes at the limestones and chemically distinctive rocks.
