Answer:
hello there
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first) and rock strata (layers) closest to the ground surface are the youngest (formed most recently). A fossil is the remains or traces of plants and animals that lived long ago.
Animal remains are most likely to be fossilized if their hard parts are covered by layers of sediments soon after death. With time and pressure, these sediments, such as sand, plant debris, or ash, become compressed into rock. Therefore, fossils are found in sedimentary rock, like sandstone, shale, limestone and coal.
