In rock layers what is usually found at the bottom?
Normally, the oldest rocks are found at the bottom of the layers, being the first of the sediments that were deposited.
Is it true that the Law of Thermodynamics says that the oldest layer of sediment will be found beneath younger layers of sediments?
FALSE
Why are sedimentary rocks formed in layers?
Sedimentation of transported weathered and eroded material is continuous, cyclical, or event based. New sediments are deposited on top of existing sediments, forming layers that may be visible in a sedimentary rock body.
How do you determine the order of rock layers?
The chronological order of rock layers is usually determined by their order in an undisturbed sequence of strata. According to the principle of superposition, the oldest layers would be found at the bottom and the youngest layers at the top. In disturbed rock layers (those that have been folded, uplifted, or generally disrupted by tectonic forces), the determination must be made based on the presence of index fossils, comparison to undisturbed strata or radiometric dating.
Where can you find the oldest fossils in sedimentary rock layers?
It would be found in the lower layers, rather that younger fossils which are found in the upper layers. ♥

Is it true that the Law of Thermodynamics says that the oldest layer of sediment will be found beneath younger layers of sediments?
FALSE
Why are sediments usually found in layers?
because they are sedimentary rock
Where are the oldest rock layers always found?
Deep in the ground.
Where would the oldest fossils be found in the rock layers?
The furthest down of all top layers.
How does superposition work?
the theory that layer of sediments are geologically younger than the layers found below it
