Intro & Maps for $100
1.Geology
2.Astronomy
3.Oceanography
4.Meteorology
What is the name of our galaxy?
The Milky Way galaxy
Alfred Wegener is credited with the idea
of ???????
Continental Drift
What is the difference between a fracture and
a fault?
A fracture is just a crack in the ground, but a fault is when there is movement along the fracture.
What are the three main types of volcanoes?
1. Shield Volcano2. Cinder Cone Volcano3. Composite Volcano (aka stratovolcano)
What determines whether a rock is
igneous, sedimentary or metamorphic?
The way that it is formed.
Which metric unit would be appropriate to give the distance from Cary
to Greensboro?
kilometers
Which scientist invented the telescope?
Galileo
Earth’s many lithospheric plates float on the ?????
asthenosphere
Where is the foot wall of a fault located?
BELOW the fault
Mt. St. Helen’s is an example of which type
of volcano?
Composite Cone
What are the two types of igneous rocks?
Intrusive Extrusive
What process do scientists use to solve
problems?
Scientific Method
Our sun is in what phase of its life cycle?
Main Sequence Star
What is the action at a divergent boundary?
AND Give an example of where this
type boundary is found.
Plates are pulling apart.Ex. mid-ocean ridges
What does the hanging wall do in a reverse
fault?
The hanging wall moves UP.
Name & describe three types of mafic lava.
Pahoehoe – wrinkled, ropey Aa – sharp, jagged chunks
Pillow Lava – globs of lava that are extruded underwater
What determines the difference between the
clastic sedimentary rocks?
Size of the particles
ex. Large = conglomerateMedium = sandstone
Small = shale
Which branch of earth science studies meteors
that streak across the sky?
Astronomy
Explain the differences between a meteor, a
meteorite, and a meteoroid.
Meteoroid – located in spaceMeteor – has entered Earth’s
atmosphereMeteorite – has crash-landed
onto Earth
What features are formed at a oceanic-to-oceanic convergent boundary AND where could you see such a boundary?
Trench and a volcanic island arc
ex. Aleutian Islands andJapanese Islands
Name the three major earthquake zones?
1. Mid-Ocean Ridges2. Pacific Ring of Fire3. Eurasian-Melanesian Belt
Which types of tephra can be carried by the
global winds and distributed worldwide?
Volcanic dust and ash
What are the two ways that metamorphic rocks
can be formed?
Regional metamorphismContact metamorphism
A student wants to determine which color absorbs heat the most. The
experiment has many different colors of paper under a lamp and the
temperature of each is recorded.
Name the Independent Variable.Name the Dependent Variable.
Independent Variable:different colors
Dependent Variable:temperature
Name and explain the theory about how our
universe began.
The Big Bang Theory states that all the matter of our universe began in
one tiny point. There was some type of explosion and all that matter and energy was flung outward and created our expanding universe.
Name the three types of plate boundaries and give
the type of stress associated with each.
1. Divergent Boundary – tension2. Convergent Boundary – compression3. Transform Boundary -- shearing
Name at least three ways that earthquakes might
be predicted.
1. The ground tilting2. Small foreshocks3. Seismic gap theory
Explain the difference between a crater and a
caldera.
A crater is a funnel-shaped pit at the top of the volcano. A
caldera is a bowl-shaped depression created when the
walls of the crater collapse.
What is the difference between a foliated and
nonfoliated metamorphic rock?
Foliated has a striped (or banded) appearance.
Nonfoliated does not have stripes (or bands).
