GEOLOGY 100, PROJECT 5 (Due Week 6)
Prior to answering the following questions make sure you read WEEK 5 Overview and Learning Resources. Also, you are expected to research outside sources from the course Webliography (under Content) and the Internet. Answers must be in APA-style paragraph form with proper APA citations. Graphics may be used to support your answers, but make sure you cite your source below the graphic.
1) Sketch or diagram “your interpretation” of the “Hydrologic Cycle”. What is the ultimate energy source for the water cycle to function on Earth? Label the major processes of the water cycle concept in the hydrosphere, atmosphere, biosphere, and geosphere. Use arrows to show the progression of water (H2O) through the cycle.
2) Define and describe the following geologic surface water terms and make sure you give a geologic location example for each term:
· drainage basin (watershed)
· drainage divide and continental divide
· stream erosion features: water falls, canyon (gorge), and V-shaped valley
· stream deposition features: stream load, alluvial material (alluvium), flood plain, and river delta.
3) Define “groundwater” and discuss its origin and role in the hydrologic cycle. Then define and describe the following groundwater terms:
· porosity vs. permeability
· saturated vs. unsaturated zones (also called zone of saturation and zone of aeration)
· water table
· aquifer (describe one in detail)
4) Visit the Virtual Caves website and then describe the geological formation of caves and caverns, with an example of each of the following cave types:
· solution caves
· sea caves
· erosional caves
· lava tube caves
5) View the video at Karst Topography: A Unique and Fragile Environment then discuss in a few paragraphs karst geology, including the origin of the term “karst”, the cave-forming rock types present, and the major karst surface and subsurface features. What is the major geologic hazard associated with karst regions? Choose one karst and/or cavern location in the USA (or other country) and discuss and describe the area, any unique subsurface life, and the human threats to this fragile environment.

Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years. A rock is found to contain 83.3% of the amount of uranium-238 that it contained when it was formed.
Module 05 – A Universe of Galaxies
Edwin Hubble’s observations of the Andromeda “nebula” in 1924, using the then new 100 inch telescope at Mount Wilson Observatory, lead to the understanding that the Milky Way was not the only galaxy, but one of a countless large groups of stars in our Universe. Within this new field of astronomy, Hubble devised a classification system for galaxies based on their observed shape and structure. In this laboratory exercise, you will use Stellarium to observe a number of galaxies and attempt to classify them using Hubble’s system.
Background Question – Describe the major Hubble galaxy classifications and how they are organized on Hubble’s “turning fork”.
Object: Explain the purpose of this laboratory assignment in your own words. What do you think you will accomplish or learn from this exercise?
Hypothesis: Write a simple hypothesis connected to observed properties of galaxies that you will be able to test using the Stellarium software (for example, most galaxies are spiral in shape like our Milky Way).
Procedure
1) Open the Stellarium software. Open the Sky and Viewing options window (F4). Under the “Sky” tab, uncheck the Atmosphere.
2) Select the Landscape tab and uncheck “Show ground”.
3) Open the Search window (F3) and enter Andromeda Galaxy. The view should shift to center on the Andromeda Galaxy. Scroll your mouse wheel forward to zoom in until you can see the Andromeda Galaxy in detail.
4) Based on the Andromeda Galaxy’s shape and appearance, record on the lab data table which major type of galaxy you think it is (Spiral, Elliptical, Irregular). Make a note if you see any particular interesting features (color, if spiral is there a bar, if a galaxy is interacting with another galaxy)
5) Repeat steps 3 and 4 for each galaxy listed on the data table. You make need to zoom in or out to see the selected in detail.
Q1: From the list of galaxies given, did you find more of classification group then the other?
Q2: Did you observe any spiral galaxies with a bar structure?
Q3: Where all the elliptical galaxies all the same exact shape?
Q3: Did you notice a difference in general color between elliptical and spiral galaxies?
Q4: Which classification group showed evidence of ongoing star formation (visible new O and B blue stars)?
6) Continue using Stellarium if you need further information to test your individual hypothesis. If you need further direction, please ask your instructor.
Conclusion: In 1-2 paragraphs, explain if your observations and data support or conflict with your hypothesis and if you have met your assignment objective. Was there any portion of the assignment that was particularly interesting or difficult?

George Hank, CEO of Walker Construction has an opportunity to bid on a contract that pays $5,500 upon completion, but the contract calls for a late performance penalty of $140 per week for each week that the project is delayed beyond eight weeks.Find the crash cost per week for each activity and determine what are the total normal costs for the project?
George Fine, owner of Fine Manufacturing, is considering the introduction of a new product line. George has considered factors such as costs of raw materials, new equipment, and requirements of a new production process. He estimates that the variable costs of each unit produced would be $8 and fixed costs would be $70,000.If the selling price of the product is set at $18 per unit, Fine Manufacturing expects to sell 15,000 units. What would be the total contribution to profit from this product at this price? $Please show/explain your mathematical solution.
