The possible answers are :
a.) Gases diffuse from areas of low concentration to areas of high concentration. 
b.) Gases diffuse from areas of high concentration to areas of low concentration. 
c.) Gases diffuse between areas of equal concentration. 
d.) Concentration has no effect on gas diffusion

The correct answer is b.) Gases diffuse from areas of high concentration to areas of low concentration. 
Gas concentrations tend to form an equilibrium over time. This means that the gas molecules diffuse from the area of high concentration to the area of low concentration in order to make the two concentration equal.

Which physical evidence supports the evolution of Earth due to deposition?
stiv31 [10]

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.
