Science TCI (Unit 5): Rocks!

What is relative dating?

• The process of determining the order in which events in Earth’s history occured

• The process of absoluting the order in which events in Earth’s history occured

• The process of determining the approximate time in which the fossil was

What is absolute dating?

• The process of determining the approximate age of a rock, fossil, or event

• The process of determining the order in which events in Earth’s history occured

• The process of absoluting the order in which events in Earth’s history occured

What is the law of superposition?

• States that in undisturbed rock layers, the oldest rock is at the bottom and the youngest rock is at the top

• States that in undisturbed rock layers, the youngest rock is at the bottom and the oldest rock is at the top

• States that in disturbed rock layers, the oldest rock is at the bottom and the youngest rock is at the top

What is an index fossil?

• A fossil of an organism that lived over a widespread area for a short period of geologic time and so can be used to date the rock layers in which it occurs

• A fossil of an organism that lived over a widespread area for a short period of geologic time and so can be used to date the rock sections in which it occurs

• A fossil of an organism that lived over a widespread area for a long period of geologic time and so can be used to date the rock layers in which it occurs

• A fossil of an organism that lived over a widespread area for a short period of science time and so can be used to date the rock layers in which it occurs

What is the principle of lateral continuity?

• States that rocks are deposited in layers that extend horizontally in all directions until they reach an obstacle

• States that sediments are eroded in layers that extend horizontally in all directions until they reach an obstacle

• States that sediments are deposited in layers that extend vertically in all directions until they reach an obstacle

• States that sediments are deposited in layers that extend horizontally in all directions until they reach an obstacle

What is the principle of original horizontality?

• States that rocks form when sediments are deposited in horizontal layers due to gravity

• States that rock layers form when rocks are deposited in horizontal layers due to gravity

• States that rock layers form when sediments are deposited in vertical layers due to gravity

• States that rock layers form when sediments are deposited in horizontal layers due to gravity

What is the law of cross-cutting relationships?

• States that the rock feature that cuts across another rock feature is the older of the two features

• States that the rock feature that cuts across another rock feature is the younger of the two features

What is the law of fossil succession?

• States that the sequence of changes in fossils as recorded by fossils is the same everywhere the fossils are found on Earth

• States that the sequence of changes in organisms as recorded by fossils is the same everywhere the fossils are found on land

• States that the sequence of changes in organisms as recorded by fossils is the same everywhere the fossils are found on Earth

What is the geologic time scale?

• A model of Earth’s history divide into eons, eras, periods, and epochs

• A model of land’s history divide into eons, eras, periods, and epochs

• A model of water’s history divide into eons, eras, periods, and epochs

What is the glacial period?

• During an ice age, a time of even cooler temperatures, when large ice sheets advance from the poles toward the equator

• During an era, a time of even cooler temperatures, when large ice sheets advance from the poles toward the equator

• During an ice age, a time of even warmer temperatures, when large ice sheets advance from the poles toward the equator
