When scientists use the law of superposition to determine the age of a fossil, they go by the principle of 'every undisturbed layer of rock is older than the layer above it. This is not the most precise way of determining age, and in fact this method can only reveal the approximate age, but not the exact one.
A thermocline is the transition layer between the warmer mixed water at the surface and the cooler deep water below. It is relatively easy to tell when you have reached the thermocline in a body of water because there is a sudden change in temperature.
