FALSE. 
during dry weather , the water level in a small pond drops NOT because of runoff but RATHER because of <u>EVAPORATION</u>. 
Explanation:
Dry weather means there is little;e relative humidity in the air mass the region. Therefore, more  water from the pond easily evaporates  because of the air’s high capacity to hold more moisture before getting to saturation. This is why water levels in water in small ponds lower or even dries up in dry conditions during the dry season.  The warmer air temperatures increase the capacity of the air to hold more moisture hence evaporation of water from the ponds is increased.

When acid rain falls, aquatic animals get affected due to the spreading of acid rain which harms and destroy wildlife, it can reach to aluminum and then to soil, which basically destroys the ecosystem of the aquatic animals.
        
             
        
        
        
I think A is the youngest layer, because of the new sediments that fell upon the animal.
