Unit 4 Assignment EVR

Part 1

Wegener’s Evidence

For part 1 of this assignment, you will be exploring the major types of evidence that were proposed by Alfred Wegener regarding the Theory of Continental Drift. As you may recall from the course reading, while his theory eventually evolved into The Theory of Plate Tectonics, Wegener laid the foundation for modern thought regarding the movements of tectonic plates.

Five types of evidence for Wegener’s theory are displayed. Review each of the evidence types.

Then, in a minimum of two sentences for each type, describe the evidence proposed.

• Jigsaw Fit
• Tectonic Fit
• Fossil Evidence
• Geological Fit
• Glacial Deposits

Then, for each of the scientists listed on the site, describe how their ideas caused the original theory to evolve into what we know today.

• Harry Hammond Hess
• Frederick Vine and Drummond Matthews
• John Tuzo-Wilson
• Dan McKenzie

Part 2

As part of this task, you will be creating a Google drawing of the following types of plate boundaries. Be sure to label each of your diagrams. Please carefully go through the if you have never used Google Draw before.

• Convergent Boundary (Subduction)
• Convergent Boundary (Collision)
• Divergent Boundary
• Transform Boundary

Part 3

Interactive Rock Cycle

• Go to:
• Go through all of the sections by participating in the interactive games and questions and by reading the text.
• Complete the “Test Your Skills” Quiz. Screen capture your results and paste the image into your assignment document.

Part 4

Soil Texture Classification

Soil has sometimes been called “the humble remains of once proud bedrock.” It is created from the leftovers that remain behind after a rock is broken down by weathering.

Today, you will observe a method of soil texture classification and complete a few practice problems that reflect what you have viewed.

Geologists generally classify soil based on the grain size of its mineral particles. These fall into three categories:

• Sand: gritty
• Silt: dusty
• Clay: fine and sticky

Complete the following steps:

1. Access the video clip below about soil texture.
2. Using the chart on your Unit 4 Assignment document, complete the provided exercise questions.
