CC3.32 Review for Final Exampart 1

• This exam is cumulative and will including
  material from Minerals, Maps, Landforms (50 of
  the questions) and the Fourth Dimension (50 of
  questions).
• Once the final exam is finalized we will let you
  know the amount of questions (will be T/F and
  multiple choice).
• You will not be tested on material from Drowning
  of NY.
• In addition to the PowerPoint review I strongly
  urge you to review your graded assignments.
• Again the final will be on 05/20/09 3127N from
  830pm-1030pm
• You are responsible to bring a pen/pencil,
  calculator, ruler and string Cell phones are not
  permitted to be used during the exam for any
  reason!

Format of the Review

• This review will cover the material on the final
  exam. The slides will be similar to the previous
  reviews but focuses on what will be on the exam.
• Links are provided to guide you back to the
  website to accurately find the information
  discussed on the slide.
• If there is a problem with a slide or link please
  email me with the slide number and I will see
  what I can do to fix it!
• From all of us Good Luck and see you in 2 weeks!

Final Exam--Minerals ?KNOW THE DEFINITION OF A
MINERAL AND A ROCK A MINERAL is a naturally
occurring, inorganic solid, with a
characteristic chemical composition, a highly
ordered atomic structure and specific physical
properties. A ROCK, by comparison, is an
aggregate of minerals (and other debris such
bones or shells) and need not have a specific
chemical composition.
? Know the difference between a mineral, crystal
and crystalline http//academic.brooklyn.cuny.edu/

Final Exam--Minerals ?KNOW HOW TO CALCULATE THE
DENSITY OF A MINERAL. Density or specific
gravity is the ratio of the weight of a substance
to the weight of an equal volume of
water. Density Weight/Volume Record the
weight of the specimen, in this case 155.8
grams.
5
Final Exam--Minerals
?HOW TO CALCULATE THE DENSITY OF A MINERAL.
The amount of water displaced 20ml 20cc
(920-900) Divide 155.8g/20cc 7.79 g/cc. So,
the density of the minerals is 7.79g/cc.

• Final Review--Minerals
• Know and understand the properties which are
  most useful in mineral identification
• For Example Hardness, Density, Streak, Color
• ? Youll be ask to identify an unknown mineral
  using these properties which will be given to you
  in the test.

Final review--MAPS
In what general direction is the stream flowing?
West to East (The legs of the letter V give you
the direction of flow)
8
Final Review--MAPS Distance Between 2 Points
(MILES)
What is the straight line distance between points
Q and T?
First We measure the scale with the ruler and
now we know that 1.5 cm 100 miles
9
Final ReviewMAPS Distance Between 2 Points
(MILES)
What is the straight line distance between points
Q and T?
Second We measure the distance between the two
points and we get 8.5 cm. So, we want to find
8.5 x miles
10
Final ReviewMAPS Distance Between 2 Points
(MILES)
Calculations
Answer The distance between pt Q and T is 567
miles.
11
Final ReviewMAPS Gradient of a Steam
Gradient Difference in Elevation/
Horizontal Distance
Scale bar length 100 miles Contour Interval
50 feet
Elevation of point Q
583 Start Point Q End Point R
What is the average gradient of the stream
between points R and T? Begin by measuring the
length of the stream. Lay carefully a string
along the course of the river.
12
Final ReviewMAPS Gradient of a Steam
Measure the string and convert to miles (see
calculations on left). 884 miles is your
horizontal distance
13
Final ReviewMAPS Gradient of a Steam
Scale bar length 100 miles Contour Interval
50 feet
Elevation of point Q
583 Start Point Q End Point R
Next Label the contours taking into account the
contour interval 50 ft and the elevation of
point Q 583 ft
Then Measure the heights of points R and T and
find the difference between them which is 100ft.
(R 500 ft, T 400 ft 500-400100ft) 100ft is
your Difference in Elevation
14
Final ReviewMAPS Gradient of a Steam ?Remember
Gradient or steepness between two points is the
difference in elevation (ED) divided by the
horizontal distance (HD) To Calculate
Gradient (Using the numbers from the previous
slides) ED (difference in elevation) 100
feet HD (horizontal distance) 884 miles
Gradient is equivalent to slope (my/x)
15
Final ReviewMAPS Labeling Contours
Scale bar length 100 m Contour Interval 50
feet Elevation of point Q 583 feet Start
Point Q End Point R
What is the elevation (in feet) of contour
d? Answer 400 ft
You will be responsible to label all contours on
a given map similar to this. http//academic.bro

Final ReviewMAPS Topographic Features
Closed Depression
Review topographic maps and what features you may
find For ex. isolated hill, closed depression,
steep slope, gently sloping plain. (do not waste
time memorizing obscure features. Focus on the
ones mentioned above)

Review for Exam 2 Geology of New York City

Final Review-- Landforms Geologic Map
Examine the geologic map shown above. The
rectangles represent outcrops of bedrock. Assume
that each of the individual formations maintains
a more or less constant thickness throughout the
region.
20
Final Review-- Landforms Geologic Map
At drill hole E we hit Formation 1 At drill hole
A we hit Formation 2 At drill hole D we hit
what Formation??
Please keep in mind you must be consistent with
the thicknesses of the beds as you draw your line
connecting Formations.
21
Final Review--Scientific Method
?A hypothesis, by definition, is neither right
nor wrong, it's simply an untested
explanation. ?A hypothesis that survives the
scrutiny of proper testing is then known as a
theory or a model (not a proven fact).

Focus on what makes the scientific method most
convincing, difference between hypothesis and
theory and the definitions listed above. There
are only 3 questions on this topic.

Final Review-- Glaciers A mere 15,000 years
ago, during the Ice Age, most of northern North
America lay under the grip of colossal ice
sheets. The effects of the advancing and
retreating glaciers can be seen in the headlands
of Cape Cod, the Finger Lakes of New York, and
the hills of Michigan.

Final Review Glaciers Grooves and striations
that show a proof for the passage of a glacier.
