Question
How does faunal succession help show what was different about the environment in the past? (1 point)
Responses

Faunal succession states that older fossils do not exist from any time before the Mesozoic era. This information indicates that the environment has not changed.

Faunal succession states that older fossils are found in upper geological layers. This information aids in absolute dating of plant and animal life.

Faunal succession states that older fossils are found in deeper geological layers. This information aids in relative dating of plant and animal life.

Faunal succession states that older fossils are found in volcanic rocks only. This information aids in the dating of tectonic plate movements.

Answer 1

The correct response is:

**Faunal succession states that older fossils are found in deeper geological layers. This information aids in relative dating of plant and animal life.**

This statement reflects the principle of faunal succession, which indicates that fossils occur in a definite and determinable order in geological strata. This order helps scientists understand the historical sequence of life on Earth and how environments have changed over time based on the types of organisms that existed in different geological periods.
