(Density dependent is the answer)
<span>Acids will break down the rocks, as the acids goes deep in the rocks cracks can form. When the cracks get to large the rock can break apart.</span>
There are five classes of food, out of this five only two provides energy; these are carbohydrate and fat and oil. Out of these two, carbohydrate provides the most energy for the body in the shortest time. This is the reason why glucose, which is the end product of carbohydrate is normally given to sport men during games.
First let me say this, i may be wrong. I think it would change over time because first of all the sandstone has different densities. Different kinds off rocks erode and get broken down by the wind at different rates. If its density is higher, it will take longer to erode
