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.
