Which of the following discoveries led to a revival of Wegener’s continental drift hypothesis?

Variation in the orientation of magnetite

Magnetite crystals points to the magnetic north pole are evidence for continental drift if:

The pole is stationary but the continent is moving

The pole is moving across the landscape

The pole is flipping with the magnetic south pole

The pole is stationary and the continent is stationary

How does the variation between the alignment of magnetite crystals and the current magnetic north pole serve as evidence to support the theory of continental drift?

It indicates that the continents have moved over time, as the rocks’ alignments do not match the current magnetic north pole

It indicates that Earth has had multiple magnetic north poles in its history

As the continents drifted apart, the rocks’ alignments gradually changed, ultimately aligning with the current magnetic north pole

It indicates the magnetic north pole has shifted significantly throughout history, causing the disparity in rock alignments on the same continent

The image above shows a bathymetric map of the Atlantic Ocean. Which geologic feature is a mid-ocean ridge?

In the middle of the Atlantic Ocean

Off the east coast of South America

If it is true that new seafloor is created at mid-ocean ridges, then

Old seafloor must be destroyed somewhere

The planet must be getting bigger

New seafloor must sink directly into the mantle

The existence of “magnetic stripes” traced in the oceanic crust reflects __________

Reversals in the polarity of the Earth’s magnetic field

Variation in composition of the oceanic crust

The evidence that old seafloor is destroyed at deep-sea trenches includes the fact that

Magnetic stripes end at the trenches

Heat flow is high at the trenches

The crust is very thin at the trenches

Which of the following statements(s) supports the idea of seafloor spreading along the Mid-Atlantic Ridge?

Changes in the orientation of magnetized minerals

Changes in the thickness of the ocean sediments

With increasing age, seafloor rocks

Collect an increasing amount of sediment

How has the understanding of plate tectonics developed since Alfred Wegener’s time

New evidence and technological advancements have greatly supported and expanded the understanding of plate tectonics.

The concept of plate tectonics has been disproven and replaced by an alternative theory.

Plate tectonics is still not widely accepted as a valid scientific theory.

The understanding of plate tectonics has remained unchanged since Alfred Wegener’s time.

What does a line of earthquake epicenters on a map through the center of an ocean indicate?

A plate boundary is in the center of the ocean

The seismometer incorrectly identified where the epicenters of earthquakes were.

The center of a tectonic plate is at the center of an ocean

Nothing since scientists can not gain information about tectonics from earthquake epicenters.

How did scientists draw boundaries around the plates?

By analyzing the locations of earthquake epicenters

By studying the patterns of continental drift

By studying the shape of the coastlines of continents

By measuring the thickness of the lithosphere

How can our understanding of plate boundaries help reduce damage from earthquakes?

By identifying plate boundaries, we can implement construction practices that are more resistant to damage in earthquake-prone areas

Understanding plate boundaries helps us control and manipulate the forces of plate tectonics to prevent earthquakes

Understanding plate boundaries can not help reduce damage from earthquakes

Our understanding of plate boundaries allows us to predict the magnitude of earthquakes before they happen

The map above shows three tectonic plate boundaries. Which boundary is responsible for the destruction of Earth’s crust?

Convergent boundary on the Peru-Chile Trench

Divergent boundary on the Earth’s Pacific Rise

Divergent boundary on the Chile Rise

Earth’s crust cannot be destroyed

What causes crustal plate movements?

Convection currents in the Earth’s mantle

What happens at transform faults?

Plates push together and form mountains

Plates subduct under each other

SELECT ALL POSSIBLE ANSWERS: Which numbered feature in the image above represents a geologic feature formed from an ocean-ocean convergent plate boundary?

3 - A single volcano above a hotspot
