Answer:
The sand is supplied to the beach more slowly than it is lost to the deep waters. This prevents sand beaches from forming.
Explanation:
The formation of sandy beaches depends on a set of environmental forces that must interact with each other. These forces are summed up by the speed at which the sand is added to the solid part of the beach and the speed at which the sand is taken by the deep waters. This justifies the reason why sandy beaches are not formed in Acadia, because the speed at which the sand is captured by the deep waters, is greater than the speed at which the sand is added to the solid part of the beach.
There is no really good reason. It could have been placed anywhere for reference of 0 degrees longitude, but at the conference it was decided that it would pass through Greenwich
