Fossil Review (3a.)

Front

What is a fossil?

Back

A fossil is the preserved remains or traces of a once-living organism, often found in sedimentary rock.

Front

What can fossils tell us about past environments?

Back

Fossils can provide clues about the climate, geography, and ecosystems of the past, helping us understand how environments have changed over time.

Front

What is the significance of finding a fish fossil in a desert?

Back

It suggests that the area was once covered by water, indicating a change in the environment over time.

Front

What does it mean if a fossilized plant has characteristics that retain water?

Back

It indicates that the plant likely lived in a dry environment, such as a desert, where water conservation was important.

Front

How can scientists infer the habitat of a fossilized animal?

Back

By examining the physical features of the fossil, such as teeth shape and body structure, scientists can make educated guesses about the animal's habitat.

Front

What is the difference between a plant fossil and an animal fossil?

Back

Plant fossils are remains of plants, while animal fossils are remains of animals. They can provide different information about past environments.

Front

Why are palm tree fossils found in cold mountain regions puzzling?

Back

Palm trees typically grow in warm climates, so finding their fossils in cold regions suggests that the climate has changed significantly over time.

Front

What does it mean if two different types of fossils are found together?

Back

It may indicate that those organisms lived in the same environment at the same time, providing insights into the ecosystem.

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation of sediments, often containing fossils.

Front

What can the size of a fossil tell us about the organism?

Back

The size of a fossil can provide information about the organism's age, species, and the environment it lived in.
