Read the excerpt from "Bone Detective," by Lorraine Jean Hopping. The Hunley recovery team planned to display Diane’s casts in a museum that was about to be built. But did the casts belong in a public exhibit? Some people objected to displaying soldiers' remains—even though they were plastic replicas. Diane saw nothing wrong with it. In fact, she had no qualms about showing the real bones.

"If people want to really learn about the soldiers,” she said, "you have to show the bones. The bone is a record of a person’s life, especially the last part—the circumstances of death.”

How and why did the Hunley sink? What can we learn about the lives—and deaths—of its ill-fated crew? Scientists will likely be investigating the answers for years to come, thanks in part to Diane’s casts.

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.

hope it !

evidence and logical support is essential for a scientist to do in order to maintain credibility. this is because no one can believe without any logic and without any evidence.hence a scientist can maintain credibility by proving himself and by answering logically so experiments prove very beneficial. logical hypothesis give conclusion which is acceptable. therefore, there are two main factors to maintain credibility by a scientist is evidence and logical support.
