NGSS.MS-ESS2-3

What do the little "whiskers" on the intrusion mean?

• Contact metamorphism

• Indicates the type of rock

• Indicates the direction of the intrusion

• Disconformity

Tags

NGSS.MS-ESS2-2

What type of unconformity occurs between layers B and C?

• Angular Unconformity

• Disconformity

• Paraconformity

• Nonconformity

Tags

NGSS.MS-ESS1-4

What is the best explanation for the irregular surface between layers B and C?

• Some sort of igneous intrusion

• A river was flowing

• Erosion

• Uplift by plate tectonics

NGSS.MS-ESS2-2

What law explains that layer 1 is the oldest and layer 6 is the youngest?

• Superposition

• Original Horizontality

• Uniformitarianism

• Cross-Cutting Relationships

Tags

NGSS.MS-ESS1-4

Which layer(s) were uplifted?

• A

• B

• D

Tags

NGSS.MS-ESS2-2

Why are the layers no longer horizontal?

• Sediment is Forming

• Igneous Intrusion

• Erosion

• Uplifting

Tags

NGSS.MS-ESS1-4

NGSS.MS-ESS2-2

Does this show a dome or a basin?

• Dome (because it is in shape of a ring)

• Dome (the oldest layer is in the middle)

• Basin (because the lines curve downward)

• Basin (because the youngest layer is on top)

What happened to the missing rock (shown by dashed lines)?

• Erosion

• Uplifting

• Contact Metamorphism

• Volcanic Activity
