Topic 6 Lesson 2 Evidence of Change from Fossils and Rock

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 are land fossils?

Back

Land fossils are fossils of organisms that lived on land, such as plants and animals.

Front

What are marine fossils?

Back

Marine fossils are fossils of organisms that lived in the ocean, such as fish, shellfish, and marine plants.

Front

What does it mean when sea levels go down?

Back

When sea levels go down, it means that the amount of water in the ocean decreases, exposing more land.

Front

What happens when sea levels go back up?

Back

When sea levels go back up, it means that the ocean water rises, covering more land and possibly burying fossils.

Front

What is sedimentary rock?

Back

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

Front

What is the significance of the oldest layer of rock?

Back

The oldest layer of rock is significant because it provides information about the earliest life forms and environments on Earth.

Front

How do fossils form?

Back

Fossils form when organisms are buried by sediment, which hardens over time, preserving their shape.

Front

What is the process of fossilization?

Back

Fossilization is the process by which organic material is replaced by minerals, turning it into a fossil.

Front

What can fossils tell us about the past?

Back

Fossils can provide information about the types of organisms that lived in a particular area, their environment, and how they changed over time.
