Announced Quiz 2 Study Guide
Announced Quiz 2 will take place during your normal lab time during the week of
April 4-10, during the first portion of class. You will be given approximately 30-40
minutes to complete the quiz. This quiz is worth 50 points and will constitute 10%
of your final grade.
Chapters to be covered on Announced Quiz 2 are:
Chapter 7 - Remote Sensing
Chapter 8 – Topographic Maps
Chapter 9 – Geologic Interpretation of RS Imagery and Topographic Maps
You will work alone on the quiz. Question formatting will be short answer, fill-inthe-blank, matching, multiple choice, etc. There will be a photocopy of a
topographic map and you will be expected to be able to locate points, recognize
geologic structures and landforms, create a topographic profile, and calculate relief
and stream gradient.
Topics to keep in mind while studying:
Chapter 7 - Remote Sensing


Definition of Remote Sensing
The main types of remote sensing imagery: thermal imagery, color imagery,
imaging radar and aerial photography and their advantages.
The uses and advantages of Remote Sensing Imagery
The appearance of vegetation with remote sensing imagery and other
features (water = black when clear and blue when sediment filled)
All aspects of Stereoscopic Viewing; you will not have to interpret actual
images for the exam, just conceptual questions.
Scaling and associated calculations
Chapter 8 – Topographic Maps




Normal map vs. Topographic map
Colors and representative features (ie, vegetation is green, population
centers are pink, etc)
The three scales represented on topographic maps
Definition of contour line and the associated rules using them. (i.e., closely
spaced contours are representative of steep slopes, enclosed contours
represent hills or knobs, etc)





Definition of bench mark
Definition of relief and calculation of relief
Definition of an Index contour and how they differ from normal contour
lines (i.e., they are bold and have the elevation noted, normal contour lines do
not)
How to locate a point on a map using the Public Land Survey System
How to create a topographic profile
Chapter 9 – Geologic Interpretation of RS Imagery and Topographic Maps


Know that contour lines and associated patterns are used in interpreting
geologic structures on topographic maps. (ie, repeating and descending
elevations (depicted by contour lines), going inward indicates a valley.
Definition of landforms and landscapes
Water as an erosional force
Stream valley types: V-shaped, floodplain
Stream types and patterns: graded streams particularly meandering streams
and the associated features (cut banks, meanders, ox bow lakes, etc),
Dendritic streams (and bedrock implications), braided stream patterns, and
alluvial fans.
Definition and significance of Gradient and how to calculate a stream
gradient
How geology influences landforms (i.e., rock resistively, etc.)
Landforms: Hogback ridges, cuestas, buttes and mesas, plateaus.
