Explanation:

An appositive is a noun or noun phrase that renames another noun right beside it. Those appositive phrases which are considered nonessential are separated from the rest of the sentence with commas.

In the sentence above, the appositive phrase is the NP "my American history teacher". This NP renames the proper noun Mr. Turner. As you can see, this nonessential appositive phrase has been separated from the rest of the sentence with commas. If it was dropped, the meaning of the sentence would be left unchanged.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.
