Answer:

Red coloration--- sedimentary environments

Yellow coloration ---- marine environments

Brown coloration ---- low temperature environments

Explanation:

Coloration of sediment samples indicates the presence of different minerals in these sediment that are found in different type of environment. Red coloration of the sediment sample is the presence of hematite in that environment. The environment that is responsible for the presence of hematite is sedimentary environments whereas, yellows colour result from limonite that is present in shallow swamps, lakes, and marine environments. and brown colour occurs due to the presence of goethite that is found in low-temperature environments.
