The sediments located in Heinrich layers contain almost exclusively<u> </u><u>ice</u><u>-</u><u>rafted</u><u> </u><u>detritus</u><u>, known as </u><u>IRD</u><u>.</u>
Heinrich layers are layers of sediment in the North Atlantic. These sediments have consist of high amounts of debris in Foraminiferida shells brought by ice. This composition explains how these layers function as a historical record of major ice releases.
These layers are formed from huge releases of ice of the Hudson Strait ice stream. The North Atlantic cores of sediment found in these layers are badly sorted and lack almost any foraminifera, being composed of primarily ice-rafted detritus (IRD).
These IRDs are described as sediments of no particular size that are carried by floating ice until they are introduced into the water and mix into the environment. This Ice carries debris located within it in the way a raft would carry a person, by allowing it to float on the surface of the water

Answer:
A) contours at around 2,000 meters depth.
Explanation:
- As the contours of the world when measured from a 2000 meters depth shows us the same orientation and fitting f the continental shelf sand the plates as the lines joined the place as they are then overlapped and hence are connected by the values that are assigned to them.
