Oceanic Plates

25
The process wherein magma escapes from earth interior to form cool and hard rock volcano
Volcanoism
26
The channel magma that travels through that reach earth's surface
Main vent
27
Opening that allows molten magma to flow outside the surface
Crater
28
Formed through the cooling and solidification of molten rocks
Igneous rocks
29
Ability to flow. If the greater the answer is.The greater the resistance to flow
Viscosity
30
A landform with an opening at the top
Volcano
31
Volcanoes that arise from the excretion of magma to the mantle known as
Hotspots
32
Rough and jagged and dangerous due to it's sharp edges
AA
33
Small fragments of rocks and minerals and glasses
Volcano Ashes
34
Process of mountain building
Orogeny
35
Refers to a large surface feature that rises above it's relative
Mountain
36
Occurs when two oceanic plates converge and as the leading type
Island arc
37
Is caused by the compression on the crust above
Continental Volcanic Arc
38
Occurs along continental plate boundaries
Andean Type
39
Lowest point of the fold
Syncline
39
The peak of any folded rock layer
AntiCline
40
Sharp peaked anticline fold
Tightfold
41
Bending or warping of folding rock layers
Overfold
42
As a result of too much bending that no vertical regions can be seen
Recombent fold
43
A fold that has overtuned causing rock layers to be fractured
Nappe
44
Is a fracture between two blocks of rock
Fault
45
A slope or inclination of any geolical surface the greater the slope the greater dip angle strike / Any horizontal line that is drawn
DIP
46
Any rocks that falls above the fault line footwall / Any rocks that falls under the fault line
Hanging Wall
47
These faults can be found along transformed plate boundaries
Strike - Slip Fault
48
A storage location of molten rock below the ground
Magma Chamber
49
A Greek word which means ''All Earth''
Pangea
50
The Three Evidence Of Alfred Wegener
Geolical Fit Glacier Coal Deposit
51
Thinnest and outermost layer of the earth
Crust
52
The primary and secondary waves travel within the interior of earth, and are responsible for the detection on the epicenter of an earthquake
Seismic Waves
53
Also known as plate boundaries
Plate Margins
54
Internal part of seismograph and works as a pendelum that swings back and forth which is attached to a barrel that rotates and makes print of the ground shaking
Seismometer
55
When lava flows on the surface of earth, It is called
Extrusive volcanism
56
Entrapped lava flow that does not reach the surface is called
Intrusive volcanism
57
Lava flow exhibits smooth-surfaced characteristics
PAHOEHOE
