About This Chapter
Below is a sample breakdown of the Weathering & Erosion chapter into a 5-day school week. Based on the pace of your course, you may need to adapt the lesson plan to fit your needs.
|Day||Topics||Key Terms and Concepts Covered|
|Monday||Mechanical weathering||Thermal expansion, frost shattering, plant activity, abrasion|
|Tuesday||Chemical weathering||Hydrolysis, oxidation, carbonation, acid rain and lichen activity, weathering rates|
|Wednesday||Soil composition||Soil profiles and horizons, soil structures, sand, silt, loam and clay|
|Thursday||Soil erosion and prevention techniques||Surface water runoff, sheet and rill erosion, gully and bank erosion, wind erosion, strip cropping, terracing and crop rotation|
|Friday||Mass wasting||Shear strength, lumps and rockslides, debris flow, earthflow, triggers for mass wasting|
1. Mechanical Weathering: Definition, Process, Types & Examples
Over time, the forces of the natural environment cause rocks to physically break down in a process called mechanical weathering. Learn how factors, such as wind, water and temperature fluctuations lead to mechanical weathering.
2. What is Chemical Weathering? - Definition, Process & Examples
Chemical weathering is what happens when rocks are broken down and chemically altered. Learn about the different types of chemical weathering, including hydrolysis, oxidation, carbonation, acid rain and acids produced by lichens.
3. Factors that Affect the Rate of Weathering
Weathering is the process that breaks down rocks into smaller pieces. The rate at which rock weathers depends on certain factors. Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering.
4. What is Soil? - Definition, Structure & Types
Soil is the material found on the surface of the earth that is composed of organic and inorganic material. Soil varies due to its structure and composition. Learn about the different types of soil and soil structures in this video lesson.
5. What is Soil Erosion? - Definition and Causes
With soil erosion, the top layer of soil is worn away due to factors such as water, wind and tillage of farmland. Learn about soil erosion and how natural elements and human activities break up and transport soil.
6. Soil Erosion: Effects & Prevention
Topsoil is lost through soil erosion. This can reduce soil quality and cause water pollution. Learn about the effects of soil erosion as well as preventative measures, including increased vegetation, terracing, crop rotation and strip cropping.
7. Mass Wasting: Definition, Types, Causes & Processes
Mass wasting or mass movement is the movement of a large mass of rock, soil and debris downward due to the pull of gravity. Learn about the process of mass wasting, the factors that must be present to trigger it and the different types.
8. Major Triggers for Mass Wasting: Water, Slopes, Vegetation Removal & Earthquakes
Mass wasting is the movement of mass amounts of rock, soil and debris downward due to gravity. Learn about major triggers of mass wasting, such as increased water, increased slope steepness, the removal of vegetation and earthquakes.
9. Types of Wasting: Slump, Rockslide, Debris Flow & Earthflow
Mass wasting is a type of erosion that results in the mass movement of rock, soil and debris down a slope. Learn about the different types of mass wasting, including slumps, rockslides, debris flows and earthflows.
