Geologic Scale Diagrams

What can we use our knowledge of weathering and erosion for in the study of Earth's history?

• To predict future geological events

• To construct a timeline of Earth's history

• To locate natural resources

• To understand the composition of the Earth's core

What is Catastrophism?

• The theory that the Earth's surface is constantly changing due to human activities

• The theory that the Earth's surface has been changed by gradual, long-lasting events

• The theory that the Earth's surface has been changed by sudden, short-lived, violent events

• The theory that the Earth's surface changes due to extraterrestrial influences

According to the Law of Horizontality, how were layers of sediments originally deposited?

• Vertically by wind

• Horizontally by gravity

• Randomly by water

• Diagonally by ice

What does the Law of Horizontality suggest about rock layers that are not horizontal?

• They have remained unchanged since their formation

• They are the youngest rock layers

• They have been changed by outside forces

• They are found only in volcanic areas
