Which is correct about fossils location and age?(1 point)
Responses
Fossils found in lower rock layers are older than fossils found in upper layers.
Fossils found in lower rock layers are older than fossils found in upper layers.
Fossils found in rock layers that have been disturbed are the oldest.
Fossils found in rock layers that have been disturbed are the oldest.
Fossils found in rock layers closest to Earth’s surface are the oldest.
Fossils found in rock layers closest to Earth’s surface are the oldest.
Fossils found in among numerous other fossils are most recent in age.
The correct statement about the location and age of fossils is:
"Fossils found in lower rock layers are older than fossils found in upper layers."
This statement is based on the principle of superposition in geology, which states that in an undeformed, undisturbed sequence of sedimentary rocks, each layer is younger than the one below it and older than the one above it. Therefore, if fossils are found in lower rock layers (assuming the layers have not been overturned or disturbed), they would generally be older than fossils found in the upper layers.
The other statements provided are not correct:
- Fossils found in rock layers that have been disturbed may not follow the principle of superposition due to the disturbance, so their age relative to other fossils could be variable and not necessarily older.
- Fossils found in rock layers closest to Earth’s surface are not necessarily the oldest; they could be in younger layers that are exposed due to erosion or other geological processes.
- The presence of numerous other fossils does not automatically indicate the most recent age; it depends on the geological context and the specific layers in which the fossils are found.
