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.the cloud layers are thicker, allowing fewer holes to see the colorful layers
Explanation:
- As the outer atmosphere of the Saturn contains about 96% of hydrogen and 3.2% of the helium. With the amounts of ammonia, the acetylene, ethane, propane, and methane are found in the atmosphere.
- The cloudy layer of the Saturn exhibits banded patterns layer similar to that the Jupiter. The composition of the clouds varies with depths and the increasing pressure and temperature that ranges from 100–160 K.
