Please choose the best description, or definition for Principle of Fossil Correlation. states that rock layers with the same unique groupings of fossils escaped from the highlands and died due to starvation. states that rock layers with the same unique groupings of fossils lived in communities to protect the herd states that rock layers with the same unique groupings of fossils are of the same geologic age. states that rock layers with the different groupings of fossils are from dead animals who died due to the ice age

Uhhh so here is what I found in the lessons about Principle of Fossil Correlation:

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
