The correct answer is - Concave shape of Wave Rock.
The concave shape of wave rock is a nice physical evidence of deposition in the Earth;s evolution. It is a land structure dated to 2.7 billion years old, and it is the basis around which the Australian continent formed. The Wave Rock structure is created by the weathering of the surrounding area, and this is exactly what proves the deposition part, because Wave Rock was bellow the ground, and that was due to the deposition of material around it over time, but since it is made out of much tougher material from its surroundings, the weathering lowered the surrounding terrain while Wave Rock remained to witness for the past.
Answer:
B. Theory
Explanation:
A theory can be changed as new information is discovered.
Hello! The largest mass extinction in Earth's history occurred about 250 million years ago, right before the dinosaurs appeared. Devonian Period ended about 355 million years ago, which was before the mass extinction occurred. Therefore, C is eliminated. The Cambrian Period came before Devonian Period, ending around 485 million years ago, which also eliminates A. Ordovician Period ended about 445 million years ago, which also before the mass extinction. B is gone, which leaves us to the last available answer choice being D. The Permian Period ended around 250 million years ago, which was the time of the mass extinction. The largest mass extinction even occurred at the end of the Permian period. The answer is D: Permian.
