What are the parts of the lithosphere?
the crust and the upper portion of the mantle
100
A seismograph measures _?_ during an earthquake. The amount of movement during an earthquake determines its severity which is measured by the _?_ scale. The point on the surface of the earth directly above where the earthquake started is called the _?_
How much the earth moves; Richter; epicenter
100
_?_ are geographical features that can form at convergent plate boundaries, divergent plate boundaries and hot spots. There are three different types: _?_, _?_, and _?_. The composition of the _?_ determines the severity of the eruption.
Volcanoes; composite, cinder cone and shield; magma/lava
100
Weathering that does not affect the chemical composition of rock is called __?__. An example of this type of weathering is _?_ during which small particles are moved by the wind or water and they break down the rocks. Another example is when water freezes in rocks and causes the rocks to break. This is called _?_
physical weathering; abrasion; frost wedging
100
Rock that forms due to heat and/or pressure is called _?_; rock that is not completely inorganic is _?_ rock which may contain fossils
metamorphic; sedimentary
200
Plate movement may occur because of convection currents in the _?_
athenosphere
200
The type of wave that reaches seismic stations first is the _?_ wave. A type of wave that does not originate from the focus is the _?_ wave. The minimum number of seismic stations necessary to find the epicenter is _?_
primary (p); surface; three
200
The type of volcano with the mildest eruptions are the _?_ volcanoes; trapped gas is found in both _?_ and _?_ volcanoes; _?_ volcanoes are make up of many layers of ash, cinders and lava
shield; composite and cinder cone; composite
200
The type of weathering that affects the chemical composition of rock is called __?__. Examples of this type of weathering are hydrolysis, acid precipitation and dehydration all of which involve _?_
chemical weathering; water
200
The _?_ of _?_ states that older rock lies under younger rock; it is used to _?_ rocks. To find the "real" age of rocks, we use radioactive isotopes. This is called _?_
principle of superposition; relative date; absolute dating
300
A region where two plates meet is called a(n) __?__, while an region where two plates are pulled apart is called a(n) __?__. When two plates slide along each other, that is called a(n) __?__
convergent boundary; divergent boundary; transform fault boundary
300
The breaking of rock along a fault line produces a natural phenomenon called a(n) _?_. These phenomena release huge amounts of _?_ in the form of _?_ waves
earthquake; energy; seismic
300
Which type of rock is made of lava? If the lava hardens on top of the earth it is called _?_; if it hardens below the surface it is called _?_
igneous; extrusive; intrusive
300
Many chemical processes involve water. The mixture of water and carbon dioxide produces _?_
carbonic acid
300
The type of rock formed as bits of other rocks are cemented together is _?_; fossils are found only in _?_ rock; most rocks are made of _?_ which have a characteristic chemical composition, occur naturally and have an orderly internal structure.
sedimentary; sedimentary; minerals
400
Evidence of plate tectonics includes alignment of _?_ rock on the ocean floor. The alignment changes because Earth's magnetic poles reverse every _?_ years.
magnetic; 200,000
400
Waves that cause the most damage during earthquakes are called _?_. They are a combination of longitudinal and transverse waves that cause a rolling motion.
surface
400
When metamorphic, sedimentary or igneous rock melts, the result is _?_
magma
400
The process by which water transports minerals to lower layers of rock is called _?_; the process by which sediment is laid down is called _?_
leaching; deposition
400
About 80% of the Earth's volume is made up of the _?_ layer of the earth
mantle
500
Movement of plates is possible because of the composition of Earth. The outer layer of earth is called the __?__ and is _?_. The next layer down is _?_ and it is _?_ on top and _?_ further down. The next layer is the _?_ which is _?_ on the outside and _?_ on the inside. Word bank: core, crust, mantle, solid, fluid, plastic
crust; solid; mantle; solid; plastic; core; fluid; solid
500
Lag time is the difference between: _?_ and is used to help calculate the distance from the focus to a seismic station
the arrival of p and s waves
500
Which type of plate movement produces mid-oceanic ridges? Shifting plate boundardies can produce _?_, _?_ and magnetic bands; the Ring of Fire is a _?_ boundary between oceanic and continental plates in which the oceanic plate _?_ under the continental plate
divergent; earthquakes; volcanoes; convergent; subducts
500
What force causes rock fragments to move downhill? Where do most earthquakes occur?
gravity; at plate boundaries

True or False: I have studied all of my graded homework, labs and quizzes. ESPECIALLY THE QUIZZES
Hopefully, its true!
