Unit 2- Earth's Structure

Explain how the movement of Earth's crustal plates can lead to the formation of mountains.

• Plates move apart, creating valleys

• Plates slide past each other, causing earthquakes

• Plates collide, pushing the crust upwards

• Plates sink into the mantle, forming trenches

Identify the current methods for measuring the age of Earth and its parts.

• Carbon dating and fossil analysis

• Law of superposition and radioactive dating

• Ice core sampling and tree ring analysis

• Seismic activity and erosion rates

FL.SC.7.E.6.3

Discuss how heat flow and movement of material within Earth can lead to volcanic eruptions.

• Heat flow causes the crust to cool and contract

• Movement of material creates pressure that forces magma to the surface

• Heat flow solidifies magma, preventing eruptions

• Movement of material causes the crust to thicken

What is the scientific theory of plate tectonics?

• A hypothesis about the Earth's magnetic field

• A well-supported explanation of the movement of Earth's plates

• A law describing the Earth's rotation

• A theory about the formation of the solar system

FL.SC.7.E.6.5

Explain how physical evidence supports the theory that Earth has evolved over geologic time.

• Fossil records show no change over time

• Rock layers show a consistent pattern of deposition

• Fossil records and rock layers show changes in species and environments

• Erosion rates have remained constant

FL.SC.7.E.6.4

Describe how the law of superposition is used to determine the age of rock layers.

• Older layers are found above younger layers

• Younger layers are found above older layers

• Layers are dated based on their color

• Layers are dated based on their thickness

FL.SC.7.E.6.3

Analyze how the movement of Earth's plates can cause earthquakes.

• Plates move apart, creating new crust

• Plates slide past each other, releasing energy

• Plates sink into the mantle, causing tremors

• Plates collide, forming mountains

FL.SC.7.E.6.5

What role does the mantle play in the movement of Earth's plates?

• It remains stationary, allowing plates to move over it

• It convects, driving the movement of plates

• It solidifies, preventing plate movement

• It erodes, causing plates to sink

FL.SC.7.E.6.1

How does the movement of Earth's plates create ocean basins?

• Plates move apart, allowing magma to rise and form new crust

• Plates collide, forming deep trenches

• Plates slide past each other, creating faults

• Plates sink into the mantle, forming basins

FL.SC.7.E.6.7

What is the difference between a scientific theory and a scientific law?

• A theory is a guess, while a law is a proven fact

• A theory explains why phenomena occur, while a law describes how they occur

• A theory is less supported than a law

• A theory is a hypothesis, while a law is a theory
