VocabularyEarth has

several layers

Continents change position

over time

Plates move apart

Plates converge or scrape past each other

Metric System


Vocabulary100

This is the thinnest least dense layer of Earth


What is the crust?


Vocabulary200

The description of Continental-continental collision


What is when a continental plate collides with another

continental plate?


Vocabulary 300A slab of Earth’s crust and

uppermost mantle.


What is a tectonic plate?


Vocabulary400

The boundary where two plates scrape past each other.


What is a transform boundary?


Vocabulary500

Scientists think that this is the main driving force of plate

tectonics.


What is convection in the asthenosphere?


Earth has several layers100

Earth's layers from the center to the surface.


What is the inner core, outer core, mantle, crust?



One of these could best be used to model Earth's layers?A. a peach pit B. the skin of a peach C. an eggshell D. a hard-boiled egg


What is a hardboiled egg?



The layers of the Earth from coolest to hottest.


What is the crust, mantle, outer core and inner core?



The difference in composition of the Earth’s layers.


What is the crust is made of cool rock, the mantle is made

of heated softer rock, the outer core is molten or hot liquid metals and the inner core is

solid metal?



Earth’s layers from most dense to least dense.


What is the inner core, outer core, mantle, and crust?


Continents change position over time

100

The name that Wegener gave the land mass that was believed to be all of the current continents

joined together.


What is Pangaea?


Continents change position over time

200Wegener’s hypothesis of

Continental Drift states this.


What is Earth’s continents were once in a single landmass

and gradually moved apart


Continents change position over time300

Wegener used these three facts to support his theory of

continental drift.

Daily Double!!!


What is (1)Mesosaurus fossils found only in Brazil and West Africa,(2) rock formations in Brazil match those in western

Africa; limestone formations in the Appalachian

mountains match those the Highlands of Scotland,and (3) fossils of tropical plants are found in Greenland;

rocks in South Africa were scratched by sheets of ice?



The discovery of these helped scientists prove Wegener’s

hypothesis of Continental drift correct.


What are mid-ocean ridges and deep sea trenches?



Scientists combined Wegener’s hypothesis of Continental Drift and mapping of the sea floor to

develop this.


What is the theory of Plate Tectonics?


Plates move apart100

The name of the boundary where plates move apart.


What is a divergent boundary.


Plates move apart 200

At a mid-ocean ridge, the pattern formed by magnetic mineralsA) is randomly arranged at the ridge B) shows that hot spots in Earth's mantle cause volcanoes to formC) is the same on either side of the ridgeD) is older along mid-ocean ridges and younger near ocean trenches


What is C) is the same on either side

of the ridge?



This is why scientists believe that the Earth’s magnetic poles have changed several times over the

history of the Earth.


What is the rock on both sides of a mid-ocean ridge or rift valley aligns with the

poles then switches direction of polarity several times as you move further

away from the ridge?



This is how hot spots can be used to track plate movement.


What is the hot spot stays in the same spot while the

plate moves which creates a chain of volcanic islands?



The names of three different types of boundaries and what

they do.


What is 1) Divergent boundary where plates move apart2) convergent boundary where plates come together 3) Transform boundary where plates scrape past each other?


Plates converge and scrape past each other100This is called Continental-Continental collision and an example of what it forms.


What is two continental plates colliding, crumpling and

folding the rock in between. The Alps and Himalayas are

examples of this.


Plates converge and scrape past each other200The type of plates that are colliding at D in the diagram below.


What is oceanic crust with oceanic crust?


Plates converge and scrape past each other300

This is the name of the boundary at A and what happens at that boundary


What is transform boundary where plates slide past each

other and crust is neither created nor destroyed?


Plates converge and scrape past each other400

This happens when an oceanic plate and a continental plate collide.(name the collision and give an example of what forms there)


What is oceanic-continental collision? It forms deep ocean

trenches and costal mountains.


Plates converge and scrape past each other500In oceanic-oceanic subduction, one plate sinks under another. Which one sinks? Why? And what does it form?


The older oceanic plate sinks because it is denser and it forms island arcs and deep ocean trenches.


Metric system100

Kg in 1000 grams.


What is 1 Kilogram?


Metric system200

Formula of density (use m=mass, d=density and v=volume)


What is density=mass/volume or d=m/v?


Metric system300

Another name for .001 second.


What is a millisecond?


Metric system400

Kilometers in five thousand meters.


What are five kilometers?


Metric system500

The name for one billionth of a meter


What is a nanometer?


Final Jeopardy The feature labeled E is a volcanic island. Describe how it formed.


Click Once to BeginWhat is

A volcanic island may form when two oceanic plates collide. One of these plates sinks into the asthenosphere. As the plate sinks, parts of it melt to form magma. This magma fuels an underwatervolcano. The volcano eventually rises above sea level and becomes an island.
