Faunal succession and fossil correlation relate to the principle of superposition because there are fossils of certain organisms in a rock layer. By knowing the order in which the organisms came and that fossils of the same age mean the rock layers are the same age, scientists can determine the age of the rock layers with the youngest layers on top. True or False

"the periodic table is arranged in order of atomic number."

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
