About This Chapter
OAE Earth & Space Science: Weathering, Erosion & Deposition - Chapter Summary
As part of a study guide course for the Ohio Assessments for Educators (OAE) Earth and Space Science test, this chapter will help you prepare for questions about weathering, erosion, wasting and deposition. Watch the series of engaging lesson videos to improve your understanding of:
- Mechanical and chemical weathering
- Factors that affect weathering
- Causes of soil erosion and preventative measures
- Slump, rockslides, debris flow and earthflow
- Triggers of mass wasting
- Glacier formation
- Effects of deposition and erosion
- How topography is reshaped
These lesson videos are taught by expert instructors who are available to assist you if you become confused about any of these topics. Also make sure to fortify your knowledge of the material by completing the lesson assessments. Use these quizzes to find areas of weakness, then reinforce your understanding of these areas by returning to the lessons via video tags or reading the transcripts.
OAE Earth & Space Science: Weathering, Erosion & Deposition - Objectives
The objective the OAE Earth and Space Science exam is to measure future Ohio educators' mastery over the scientific studies of Earth and space with 150 computer-based multiple-choice questions administered in a 180 minute testing session. Of these questions, 25% will ask you about topics of geology and including some questions about weathering, erosion and deposition. The purpose of this chapter is to help you improve your understanding of the causes and effects of these processes so that you will be able to answer related questions on the exam in an accurate and efficient manner.
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 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.
5. 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.
6. 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.
7. 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.
8. What Are Glaciers? - Definition, Types & Processes
Learn about the two major types of glaciers: continental and alpine glaciers. These glaciers shape the landscape around them and affect our everyday lives, even if the nearest glacier is thousands of miles away.
9. The Effect of Accumulation & Wastage on Glacier Formation
Glaciers grow through a process called accumulation and waste away through a process called wastage, or ablation. Learn about these processes and how they are used to determine the health, or mass balance, of a glacier.
10. Glacial Erosion: Definition, Processes & Features
Glaciers are huge blocks of ice that move along the landscape, carving distinct features along the way. Learn about the glacial erosion processes, plucking and abrasion, and the features they create, including cirque, horns, arête and roche moutonnee.
11. Glacial Deposition: Definition & Results
As glaciers move and retreat, they push and drop rocks and sediments in a process known as glacial deposition. Learn about this glacial process and the interesting landforms that result from it, including moraines, erratics and drumlins, in this lesson.
12. Effect of Erosion and Deposition on Landforms
Landforms are constantly being broken down and reformed by the processes of weathering, erosion, and deposition. In this lesson, we explore chemical and physical weathering and how the face of the earth gets changed.
13. The Effects of Deposition on Shoreline Features
Shorelines constantly change due to the depositing of sand and sediment, which is a process known as deposition. Learn about shoreline features that are created by deposition, such as spits, baymouth bars, tombolos and barrier islands.
14. Acid Deposition: Definition, Causes & Effects
In this video lesson, you will learn what causes acid deposition and how it forms in the atmosphere. You will also see some examples of the damage that acid deposition can cause to natural ecosystems and man-made structures.
15. What Is Topography and How Is Topography Reshaped?
The topography, or surface of the Earth, is constantly changing shape due to many powerful forces. In this lesson, we will learn about some of the amazing changes that occur on Earth due to the processes of weathering, erosion, and deposition.
