A Bit of This, A Bit of That
100

When one plate moves under another due to relative density.

What is subduction?

100

A divergent boundary on a continent will form this.

What is a rift valley?

100

The only liquid layer of the earth, responsible for the magnetic field.

What is the outer core?

100

SURPRISE BONUS (+200): In Seafloor Spreading, new crust is made at this feature while old crust is recycled at this feature.

What are mid-ocean ridges and deep-ocean trenches? 

100

The term for evidence of ancient magnetism.

What is paleomagnetism?

200

Island arcs, trenches, and volcanoes form here.

What is an oceanic-oceanic convergent boundary?

200

Developed divergent boundaries that create new seafloor are called this.

What are mid-ocean ridges?

200

The largest layer of the Earth (by composition).

What is the mantle?

200

These two geologists are responsible for the development of the Continental Drift Theory and the Seafloor Spreading Theory, respectively. 

Who are Alfred Wegener and Harry Hess?

200

DAILY DOUBLE (x2): This theory proposes that the lithosphere is broken into fragments that float along the asthenosphere, driven by convection currents.

What is the Tectonic Plate Theory?

300

Non-volcanic mountains form here.

What is a continental-continental convergent boundary?

300

All boundaries share this feature.

What are earthquakes?

300

This layer of the earth is composed of the crust and upper mantle. It floats along the asthenosphere creating tectonic plates. 

What is the lithosphere?

300

This increases as you move farther away from a mid-ocean ridge.

What is the age of the rocks?

300

These drive the movement of plate tectonics.

What are convection currents?

400

Continental-continental convergent boundaries undergo this process.

What is collision?

400

This occurs to crust at a transform boundary.

What is nothing (neither created, nor destroyed)?

400

This layer of the earth is composed of solid nickel and iron.

What is the inner core?

400

When comparing continental crust and oceanic crust, this crust is older.

What is continental crust?

400

The earth can be divided into these three layers based on their composition.

What are the crust, mantle, and core?

500

This plate subducts at an oceanic-oceanic convergent boundary because of this property.

What is the older plate because of density.

500

The primary features (two) of a transform boundary. 

What are earthquakes and faults?

500

These form in the mantle of the Earth, drive tectonic plate movements, and are the result of this property.

What are convection currents as a result of density?
500

These four pieces of evidence supported Wegener's concept of Continental Drift.

What are the fit of the continents, fossils, rock records, and climate data?

500

The earth can be divided into these five layers based on properties.

What are the lithosphere, asthenosphere, mesosphere, outer core, and inner core?
