UNIT QUIZ: Unit 8 Review Quiz

Take this quiz only after you've gone over the materials for this unit (Weathering, Erosion, Mass Wasting).

This quiz contain 35 questions about the topics/ideas/concepts discussed in this unit and will be used to measure your understanding of these topics/ideas/concepts. Questions will be taken from both the readings and video resources presented in this unit.

You can take this quiz multiple times, but you'll need to get 80% or higher before you can proceed to the next unit. If you do not reach 80% on your first attempt, use it to identify your knowledge gaps (concepts from the video that you are still struggling to understand). Once you identify these gaps, go back to the reading and video materials and review these concepts BEFORE starting your second attempt at the quiz. Only the highest grade among all your attempts will be uploaded to the gradebook.

The essential learning outcomes for this unit are:

• Distinguish between mechanical and chemical weathering;
• Describe several processes that contribute to mechanical weathering;
• Explain the three types of chemical reactions involved in chemical weathering;
• Summarize the conditions of climate, topography, and rock composition that are conducive to different types of rock weathering;
• Identify the end products of weathering;
• Describe the soil horizons found in most soils;
• Explain why soils from different climates have different profiles;
• Discuss the links between human activities and soil erosion;
• Distinguish between weathering, erosion, and mass wasting;
• Define turbulent and laminar flow;
• Describe how ice, water, and wind, transport regolith across Earth's surface;
• Define and give examples of mass wasting by slope failure and by sediment flow.
