• How a mountain form?

Which of the following observations would provide the strongest evidence for the claim that a certain organism had gone extinct at some point in the past? Marks 2

• Fossil evidence shows that the organism was often killed and eaten by animals that lived at the same time.

• Fossils of the organism are found in the older rock layers, but no fossils are found in younger rock layers.

• For a certain time period in the past, scientists have found rocks in certain areas where the fossil is not found.

Fossils are best used to show evidence of - Marks 2

• the processes that change Earth over time.

• organisms that will live in the future

• plants and animals that lived long ago.

• behaviors of extinct organisms.

• The population will increase.

• The population will stay the same.

• The population will continue to decrease and possibly become extinct.

• The population will decrease a little more, but then begin to increase.
