the idea that younger rock layers are deposited on top of older rock layers in an undisturbed section of sedimentary rock can best be explained by which of steno's principles? a. principle of superpositionb. principle of original horizontalityc. principle of original lateral continuityd. principle of faunal succession

Option (A)

Explanation:

The law of Superposition was introduced by Nicolas Steno in the 17th century. According to this law, in an undisturbed sedimentary rock layers or sequence, the rocks that are found at its base are the oldest rocks and the rocks that are found at the apex indicates the youngest rocks.

In nature, all sedimentary sequences do not satisfy this principle, because sometimes, some sedimentary sequences are affected by several factors such as the plate tectonic activity, earthquake, and faulting.

The Steno's principles were a huge contribution to the field of geology.

Thus, the correct answer is option (A).

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
