Cookie on the top shelf get done before cookies on the bottom shelf because of heat transfer in the oven
Explanation:
Heat generated by the electric oven at bottom is transferred to the top. The cookies at the top absorbed the hot air(heat) which begins the baking process and sends the cold air to bottom of the oven. This continues until the entire oven has a uniform hot temperature. By this time, the cookies at the top is almost baked and the cookies at the bottom is just beginning the process of baking. As the process continues the cookies at the top completes the baking process before those at the bottom.
