The study of the earth's structural features is known as ___TECTONICS______________.
The _LITHOSPHERE__________ is the thin, solid, outer layer of the earth above the asthenosphere.
The theory of ____ISOSTASY_________ is the balance maintained by the earth’s crust as it “floats” on the lithosphere. Glaciers
weight down the continents, erosion then continent building help them rise.
The earth’s continental crust is mostly composed of __GRANITE SIAL______ and the ocean floors are primarily composed of
__BASALTIC SIMA_____.
The point in the earth where rock fractures, resulting in an earthquake is known as __FOCUS_____.
Point on the earth’s surface directly above the focus is known as the __EPICENTER_________.
___VISCOSITY_______ is the resistance to flow of a liquid, such as magma. Magma composed of andesite and granite (SILICAGASSY) have a _HIGH_____ _VISCOSITY (LOW FLOW)-HONEY-Composite_______ and are quite explosive, while magma
composed of basalt has a __LOW___ __VISCOSITY (HIGH FLOW)-Maple Syrup-Shield________ and are quite runny.
____MAGMA____ is molten rock under the earth’s crust, from which igneous rocks are formed. __LAVA__________ is molten
rock that reaches the earth’s surface from volcanic activity.
_IGNEOUS_________ rock formed from the solidification (cooling) of magma below and above the earth’s surface.
This type of rock was changed by great heat and pressure from its original state ___METAMORPHIC_________.
The weathering and erosion of the earth’s crust is deposited in layers. The compaction and cementation of these layers results
in this type of rock ____SEDIMENTARY______.
A very large ocean wave caused by an underwater earthquake or volcanic eruption is known as a ____TSUNAMI_____.
The upper part of the mantle responsible for plate movement where convection currents are found is known as the
________ASTHENOSPHERE_____.
__INTRUSIVE________rocks solidify underground, and ____EXTRUSIVE______igneous rocks solidify on the surface.

Part B-Matching (15 marks):
11. _D____This plate boundary is where ocean and continental plates crash into each other forming volcanic mountain ranges.
12. __H___ This plate boundary is where two plates move away from each other.
13. ___J__ This plate boundary two plates crash together forming fold mountain ranges.
14. __A___ Earth quakes are the predominate tectonic force at this plate boundary
15. __B___ a gently rising, smooth-shaped volcanic dome formed from low viscosity
16. ___F__ mount saint Helen’s is an example of this volcanic dome
17. ___I__ steep sided volcanic cone with a large summit crater, composed mainly of ash and cinder spewed out from the vent
18. ___E__ a large crater formed by a volcanic explosion or by a collapse of a volcanic cone.
19. ___C__created where sections of the crust move apart and a block of land drops between two parallel faults to form a valley.
20.___G__formed where two plates are compressed forcing a block of land upwards between two parallel faults.
21. __N___A fault resulting from two diverging plates and downward movement of a block of land.
22. __K___A fault resulting from two plates compressing and the upward movement of a bock of land
23. __O___rock beds that have been folded or bent up upwards to form mountains or hill because of compressing
24.___L__rock beds that have been folded or bent downwards to form a valley because of compression
25.___M__a major zone of fractures in the earth’s crust extending down the California coastline
