Earth's History

Geologic time is divided best into units based on:

• geologic changes

• fossils and rocks

• types of trilobites

• types of life forms living during certain periods

NGSS.MS-ESS1-4

The type of Earth material most likely to contain fossils is:

• igneous rock

• metamorphic rock

• sedimentary rock

• native material

Trilobite that lived for a short period of time and was abundant is an example of a(n):

• trace fossil

• permineralized fossil

• original remain

• index fossil

7-To learn how Earth’s atmosphere has changed over time scientists study air bubbles in which of the following?

• pollen

• ice cors

• rocks containing uranium

• fossils in sedimentary rock

8-Rocks and fossils that are similar are found in Asia and Africa. This is evidence of: Continental Drift Fossil Record Law of Superposition Rock Cycle

• continental drift

• fossil record

• law of superposition

• rock cycle

9-A scientist wants to find the relative age of a rock. He most likely would use: A-radioactive dating B-law of superposition C-the geologic time scale D-ice cores

• radioactive dating

• law of superposition

• the geologic time scale

• ice cores

In which situation will older rock layers lie above younger rock layer?

• Rock layers have been overturned by folding - plate tectonics

• Erosion has exposed older rocks, and new layers have been deposited

• Sedimentary rock layers have remained undisturbed after deposition

• Igneous intrusions have cut through layers of sedimentary rock.

Unless a layer of rocks has been overturned or shifted, the bottom rock layer:

• has fossils

• is the oldest

• has the greatest amount of minerals

• has the hardest rocks

The fish fossil is older than the amphibian fossil which is older than the reptile fossil ...... this is an example of:

• Absolute Dating

• Relative Dating

• Superposition

All of the discovered fossils make up a collection known as the:

• index fossils

• law of superposition

• fossil record
