Fossils

Species remain unchanged over time.

Species change over time due to helpful traits being passed on.

All individuals in a species are identical.

Evolution only occurs in fossils.

Faults are breaks in the Earth's crust where rocks move, while folds are bends in rock layers caused by pressure.

Faults are formed by volcanic activity, while folds are formed by earthquakes.

Faults are always older than folds, while folds are always younger.

Faults and folds are both caused by erosion.

Species remain unchanged over time.

Individuals with helpful traits are more likely to survive and reproduce.

All species are identical.

Fossils do not provide any information about evolution.
