Exam to be completed at home
Introduction
The exam is divided into four portions. Each part has its own set of instructions to follow.
There are a series of questions in Section One that are based on the lecture materials on mass movements. Section One’s responses are multiple-choice.A series of short answers and multiple-choice questions on a variety of geomorphic structures and processes appear in Section Two. In Section Two, a Google Earth file is used to depict a succession of places.
These are long-answer questions based on Google Earth locations in Section Three.
A question in Section Four describes the features of a certain soil order.
Making use of Google Earth
As part of this exam/assignment, you will need to use a Google Earth file. The kml extension is used for Google Earth files.
To open these files, launch Google Earth (or Google Earth Pro), then select Open’ from the File’ menu and choose the appropriate file. When you view a kml file, you’ll see a list of labeled locations under the header “Places.” Double-click on one of the labels to go to that area (e.g. Location 4). The locations can be seen from either a straight or oblique perspective. We’re looking at an example of a location in the image to the right. An oblique view of the same place may be found at the top of the next page
By selecting the clock symbol from the menu bar in Google Earth, you can examine imagery from various dates. This will bring up a timeline slider, which you may use to select imagery from specific dates. The timeline slider’s format changes between Google Earth versions, but it always allows you to switch between dates.
Using the above tool to study gradients may be useful in some of the multiple-choice and short answer problems. When using Google Earth for this investigation, the Borders and Labels’ Layer should be enabled, while the other layers can be deactivated

1st Section (12)
This section has 12 multiple-choice questions about landforms and mass movement processes.
(12) Multiple-Choice Questions
1. On a hillslope, there is fine-textured soil or silt. The texture of the substance is silty clay. The substance has a low moisture content at first. There has been a long stretch of rainy weather, which has increased the moisture content of the sediment. When the moisture content of the sediment reaches a critical level:
a. The material’s shear strength will improve.
b. The silt’s consistency will shift, and it will start to behave like an extremely viscous mixture of sediment and water.
c. Because of the rise in cohesion, the likelihood of a mass movement will be lowered.
d. The substance will take on the properties of a brittle, hard solid
2. The moisture content of granular material (soil or silt) on a slope is low. The moisture content of the material is elevated to a very high percentage by volume during a long period of rainfall. The granular material’s shear strength is:
a. will not change since granular materials’ strength is unaffected by moisture content.
b. Because the higher pore water pressure reduces the effective normal stress, it will be reduced.
c. as a result of an increase in cohesion
d. since moisture acts as a cementing agent, will be lowered
3. A topple style of mass movement entails the following:
a. a forward rotation of cohesive material slab

7. Which of the following mechanisms is most likely the most common source of soil creep in southern Ontario?

b. The soil’s expansion and contraction as a result of daily temperature cycles from warm to cold
(expansion) in a cold environment (contraction)
c. The seasonal growth of salt crystals causes the soil to expand and compress.
In the soil zone, they expand (expansion) and then contract (contraction).d. The expansion and contraction of the soil caused by the formation of ice in the soil zone (expansion) and its subsequent melting (contraction).
