seismology
11
What is the inner most layer of the Earth?
outer core
mantle
Inner core
crust
12

It is less dense than the plate it moves under.
It moves horizontally in the opposite direction.
It is pushed up and over the continental crust.
It sinks into the mantle, forming a trench.
13
What does a convergent, continental to continental create?
mountains
rift valleys
volcano
mid-ocean ridge
14
what type of rock is formed by heat and pressure?
sedimentary
metamorphic
chemical
igneous
15
Which type of rock is formed by compaction and cementation?
metamorphic
organic
sedimentary
igneous
16
Where is new oceanic lithosphere most likely created?
transform boundaries
divergent boundaries
convergent boundaries
17
What are the 3 MAIN layers of the Earth
crust, mantle, lithosphere
crust, mantle, core
mantle, inner core, outer core
crust, outer core, inner core
18
Who was known for the theory of Continental drift?
Wagner
Wegener
Weganer
Wagener
19
Why was Wegener's theory of continental drift not accepted?
the plates never moved
No data
data incomplete
couldn't explain how they moved
20
Identify the "G" in the diagram.
heat and pressure
cementation
melting
weathering and erosion
21
What is a break or crack in a rock mass where movement of Earth’s crust occurs?
earthquake
epicenter
fold
fault
22
what happens when oceanic crust slides under continental crust?
rift valley

23
What rock is formed by cooled magma?
metamorphic
sedimentary
igneous
chemical

What is process in which rocks continually change?
rock cycle
melting
geology
volcanic eruption
25
What are convection currents responsible for?
geology
plate tectonics

How are hot spots and island formation related?
create plates and cause movement with convection currents
Plates are formed by new hot spots when islands are formed
Plates move over hot spots and cover up new islands
magma wells up through weak crust and forms islands
