Instructions

Not all of the Viewing/Video Lessons have Questions for Reflection. There are six Viewing Lessons for which there are Questions for Reflection available--they are noted on your schedule of assignments as having Q4R. Choose three of the six Viewing Lessons which interest you the most, and answer the Questions for Reflection that pertain to those Viewing Lessons. The available Questions for Reflection for all six Viewing Lessons are listed below. Answers should be a maximum of two paragraphs per question. Submit your responses to the Dropbox. The links to the Dropbox are available from the Schedule Page, as well as below in the Dropbox section.

The three Questions for Reflection assignments can be turned in early, but they must be turned in by Unit 12--that is Week 12 of a course that is 16 weeks long or Week 6 of a course that is 8 weeks long. Please check your Schedule Page for due dates.

Save your files as .doc or .rtf files and save them with a title that reflects their content.

Viewing Lessons

  1. The Sea Floor
  2. Earth's Structures
  3. Evolution Through Time
  4. Weathering and Soils
  5. Metamorphic Rock
  6. Wind, Dust and Deserts

The Unit 2 -- Sea Floor

Lesson Goal: Understand the nature of major sea-floor features such as the mid-oceanic ridge, oceanic trenches, and fracture zones, as well as the surprisingly young age of sea-floor rocks.

  1. Describe how the sea floor is studied.
  2. Describe the geologic nature and significance of the mid-oceanic ridge.
  3. List the fundamental differences between continental and oceanic crusts in terms of their structure, age and rock type.

Earth's Unit 4 -- Structures

Lesson Goal: Recognize how bed rock responds to tectonic forces originating deep within Earth.

  1. Compare and contrast stress and strain.
  2. Distinguish between joints and faults. What makes a fault active?
  3. Explain what each type of unconformity implies about the sequence og geologic events.

Unit 6 -- Evolution Through Time

Lesson Goal: Describe the development of life on Earth.

  1. Describe the major types of life that dominated the Precambrian, Paleozoic, Mesozoic and Cenozoic Eras.
  2. Describe the processes that can either destroy the remains of an organism or cause them to become fossilized.
  3. State the various explanations for mass extinctions, such as the extinction of the dinosaurs.

Unit 8 -- Weathering and Soils

Lesson Goal: Understand how minerals and rocks change when they are subjected to the physical and chemical conditions that exist at Earth's surface.

  1. Describe the relationship among weathering, erosion and transportation.
  2. Compare and contrast mechanical and chemical weathering.
  3. Explain how climate affects the formation of soils.

Unit 9 -- Metamorphism

Lesson Goal: Understand the causative factors of metamorphism and the kinds of rocks produced.

  1. Compare the two most common types of metamorphism- contact (thermal) metamorphism and regional (dynothermal) metamorphism and the types of rocks that result from each.
  2. Explain the concept of metamorphic facies and how it relates to the classification of metamorphic rocks and their environment of origin.

Unit 11 -- Wind, Dust and Deserts

Lesson Goal: Understand the formation and location of deserts and their geologic features.

  1. Indicate where deserts are typically located and give some reasons for their geographic distribution.
  2. Compare wind and water as agents of erosion and deposition.
  3. Explain desertification and its relationship to human activity.

Dropbox

The drop boxes work like e-mail. After you click the drop box link, a window will open asking for your name, e-mail address, and allow you to browse your system for your file. You must save your files in a .doc or .rtf format or I cannot read them. Please save them with a name that indicates their content. For example: Reflection--Evolution, Q4R Weathering, or just the title of the lesson. You need to clearly and completely fill out all the information requested. To send in your assignment, click Browse, and find the assignment on your computer, e.g., a Word document that you want to submit. Click on Upload (which does the same thing as attaching a file to an e-mail). You should then receive a confirmation that the upload was successful.
