Row 1, Col 1

Name the layers of the Earth in order from thinnest to thickest

Crust, core, mantle

1,2

Name the 3 types of heat transfer

Conduction, convection, radiation

1,3

What type of rock make up themajority of continental crust?Which type of crust, oceanic orcontinental, is generally older?

Granitic

1,4

What scientist helped to discoverthe process of sea-floorspreading? What type

of technology was availableto him that helped him

prove his theory?DD

Harry Hess, sonar

2,1

What is the main type of rock in oceanic

crust?

Basalt

2,2

How does the density of most Liquids and/or gases

substances change when heated?Why?

molcules in the substance move apart and make it less dense

2,3

The Pacific ocean is shrinking!Explain how this

could be happening

More oceanic crust is subducting than is beingcreated at mid-ocean ridges

2,4

Name 3 plates that interact with the North American plate

OldesJuan de Fuca, Pacific, Eurasian, Afican

3,1

What layer(s) of the Earthmake up the lithosphere?

Explain

Very uppermost part of the mantle and crust

3,2

Describe how convection currents form in a lava lamp?

Heat=less dense=rises=cools=increase density=cycle

3,3

Name and explain 3 pieces of evidence

that supported Wegener’s hypothesis

Matching coastlines, fossils/climate, land feature

3,4

What type of boundary formed Iceland?

Name the 2 plates

Divergent (C-C)

4,1

Name 3 island arcsformed by the Ring

of Fire

4,2

Besides from the sun,name 2 other examples of

radiation

Heat from stove, heat from fire

4,3

Name two continentsthat lie on the equator

S. America,Africa

4,4

Name one actual place here onthe N. American plate, formed

by each type of plateboundary

DD

San Andreas Fault(T) / Cascades (C) /Mid-Atlantic Ridge(D)

5,1

How do we know whatthe interior of the Earth is like?

Seismic waves, age of rock on ocean floor

5,2

Name 2 ways heat transferis happening to you right now.

Conduction from body heat, heat is radiating from heater

5,3

Why was Wegener’s hypothesisrejected?

Could not explain what force pushed and/or pulled the

continents

5,4

Name one feature that occursat each of the 3 plate boundaries

Mountains, valleys, trenches, islands, volcanoes
