Which of the following best describes where the youngest and oldest crustal rocks can be found on the Earth?

The oldest crustal rocks are found on continents and the youngest on the ocean floor.

A section of crust that moves as a unit

A small part of the core Earth's core

A location of high volcanic activity

A location where new crust is formed

Which of the following statements regarding a convergent plate boundary between continental crust and oceanic crust is not true?

Oceanic crust changes into continents.

Hot spots that may create volcanoes are formed.

Oceanic crust reenters the mantle.

Rock A contains a high percentage of radioactive uranium and a small percentage of lead. Where would you be more likely to find Rock A?

In one of the oldest continental rocks

Symmetrical magnetic stripes in the ocean floor on either side of a mid-ocean ridge support–

the spreading of ocean floor on both sides of oceanic ridges.

the radioactive decay of uranium into lead.

the subduction of oceanic crust into the mantle.

the formation of the supercontinent Pangea.

How has the Earth's magnetic field changed over time

The magnetic field has reversed over time

The magnetic field has never changed over the last 4.6 billion years

Earth recently "gained" a magnetic field over the last 1,000 years due to human activity

The magnetic field has been slowly declining in strength

What is the relationship between seafloor spreading and the Earth's magnetic field?

The Earth's magnetic field is unaffected by seafloor spreading.

Seafloor spreading creates new oceanic crust, which is magnetic, and the Earth's magnetic field causes the crust to spread.

The Earth's magnetic field causes the seafloor to spread, creating new oceanic crust.

The cooling of magma during seafloor spreading creates magnetic stripes in the ocean floor, which reflect the Earth's magnetic field at the time of cooling.

How does seafloor spreading influence sea levels?

Seafloor spreading has no effect on sea levels.

Seafloor spreading causes sea levels to rise by creating new ocean floor.

Seafloor spreading causes sea levels to fall by creating new ocean floor.

Seafloor spreading causes sea levels to fall as the newly formed ocean floor cools and sinks.

What happens at a passive plate margin?

areas where a single tectonic plate transitions from oceanic lithosphere to continental lithosphere

areas where two tectonic plates collide (run into each other)

areas where two tectonic plates diverge (move away from each other)

areas where two tectonic plates move past each

What is the correct order (starting from the surface) of Earth’s layers?

crust, mantle, outer core, inner core

crust, outer core, inner core, mantle

mantle, outer core, inner core, crust

outer core, inner core, crust, mantle

Which of the following statements is true about the ocean floor?

It is constantly being recycled.

It is older than the continents.

It is composed mainly of granite.

What role do ocean trenches play in the process of plate tectonics?

They are locations where crust is destroyed.

They are sites where new crust is formed.

They are areas of high volcanic activity.

They are regions of crustal expansion.

What is the primary force that drives the movement of tectonic plates?

Convection currents in the mantle

Gravitational pull from the moon

How does the age of oceanic crust compare to continental crust?

Oceanic crust is generally younger than continental crust

Oceanic crust age varies greatly and cannot be compared

Oceanic crust is generally older than continental crust

If the Earth did NOT have a liquid outer core, how would earthquake waves travel differently.

P and S waves would both be absorbed.

Only S waves would travel through the Earth's core.

S waves would travel faster than P waves.

What causes the tectonic plates of Earth to continually move?

convection currents in the mantle

volcanic and seismic activity in the crust
