Study Guide for Spring 2010 ENVI 110 Lab Final Exam Date: May 07 2010

1. Structure topics [KNOW or CREATE RULES TO HELP]

Solve map view and cross-section view geological units that may be deformed or not.

Understand and use the symbols that express the attitude of deformed (tilted, folded or faulted beds).

Know strike and dip, both rigorous definitions and how to measure and plot the measurements.

Terms to understand:

Plunge

Fold Axis

Plunge direction

Attitudes of faults as well as beds

Formation

Outcrop

6 Principles to determine Relative Age relationships

2. Geological Map skills (Assumed skills on topo maps)

Recognize large-scale features (folds and faults) as well as smaller details on geologic map

Understand the Legend or Explanation section of geologic map – age, rock type and formation names and symbols given.

Understand the cross-sections on a geologic map if printed on map

Understand the scale of map and the border positions (latitude/longitude)

Scales are almost always given as both fractional scale and bar scales; recognize that bar scales are more accurate when used carefully

Understand basic stream and river concepts and how they interact with contours

3. Fluvial processes – San Diego River Field trip gave many examples of how humans interact with rivers

Concepts: Discharge

Gradient

Energy of deposition or energy of erosion

Flood Plains

Flooding

Measurements of stream flow (stilling well for example)

Channelization and its purposes

Drainage patterns

4. Mountain/Desert Field Trip:

All rock types igneous to sedimentary to metamorphic (know how each forms and inter-relationships with each other – not just identification)

The tectonic phases or chapters of the So Cal region with observed evidence

Processes that operate at major tectonic boundaries

How the weather plays role in landscape formation, example here is rain-shadow effect (AKA orographic lifting of moist air)

5. Weather and Atmosphere

Measurements done in lab and field trips (pretty minimal measurements done)

Knowledge of structure of atmosphere with regard to pressure, temperature.

Understand water, the unusual substance, its 3 phases that exist on earth.

Coriolis sense

High and Low pressure regions as they relate to larger weather system

How do air masses move both vertically and horizontally

Reading weather maps (several special symbols used)

Predicting storm movement

Predicting wind changes as storms pass an area (weather map sense again)
