The correct response is the body of a jellyfish. Jellyfish are primarily composed of soft tissues, which do not fossilize well, leading to a scarcity of fossil records for them. In contrast, the shells of a crab, snail, and the bones of dinosaurs are more likely to leave fossil evidence due to their hard structures.

The response that best supports the evidence that an asteroid collision may have caused the extinction of dinosaurs is:
Rare metal on Earth called Iridium is found in layers where dinosaurs disappeared.
The presence of iridium, which is more common in asteroids than in the Earth's crust, in the geological layer corresponding to the time of the dinosaurs' extinction provides strong evidence for the asteroid impact hypothesis.
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 among numerous other fossils are most recent in age.
Fossils found in among numerous other fossils are most recent in age.
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 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 that have been disturbed are the oldest.
The correct statement about fossils' location and age is:
Fossils found in lower rock layers are older than fossils found in upper layers.
This principle is known as the Law of Superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest layers will be at the bottom, and the younger layers will be at the top.

The correct response is:
They are based on important events that happened in Earth’s history.
The divisions of the geologic time scale are not equal in length because they relate to significant geological and biological events, such as mass extinctions, the appearance of major groups of organisms, and other pivotal changes in Earth's history.
