About This Chapter
Who's it for?
This unit of our Middle School Earth Science Homeschool course will benefit any student who is trying to learn how topography gets reshaped. There is no faster or easier way to learn about the shaping of the Earth's surface. Among those who would benefit are:
- Students who require an efficient, self-paced course of study to learn how erosion, flooding or a natural event can affect the Earth's surface.
- Homeschool parents looking to spend less time preparing lessons and more time teaching.
- Homeschool parents who need an earth science curriculum that appeals to multiple learning types (visual or auditory).
- Gifted students and students with learning differences.
How it works:
- Students watch a short, fun video lesson that covers a specific unit topic.
- Students and parents can refer to the video transcripts to reinforce learning.
- Short quizzes and the Shaping the Earth's Surface unit exam on matter confirm understanding or identify any topics that require review.
Shaping the Earth's Surface Unit Objectives:
- Give the definition of typography.
- Discover how stream valleys are formed.
- Explore the geological progression of a landscape.
- Learn how to read a landform diagram.
- Learn how natural events such as landslides and earthquakes can alter habitats.
- Discover how beaches function as dynamic systems that transport sand via waves.
1. 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.
2. 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.
3. How a Landform Diagram Describes the Geological Progression of a Landscape
This lesson describes what a landform diagram is. We'll also discuss some basic laws of geology that can help scientists deduce both the order of events that create a landform and the geologic events that occur after a landform's formation.
4. The Formation of Stream Valleys
Running water is very powerful and has the ability to change the land around it. In this lesson, we will explore the creation of stream valleys and how they are shaped by the water that runs through them.
5. Characteristics of Shorelines & Beaches
Shorelines and beaches are constantly changing due to forces, such as waves, winds and currents. Learn about characteristics of shorelines, including headlands, bays, beach berms, sand dunes, spits, tombolos, barrier islands and lagoons.
6. Beaches as Dynamic Systems
Did you know that lava can create sand or that beaches change with the seasons? In this lesson, we will explore how beaches are formed and why they are constantly changing, due to the action of waves and the movement of sediment supplied by rivers and streams.
7. How Rivers and Streams Affect the Earth's Surface
Rivers and streams are powerful, ever-changing systems that can alter the surface of the Earth. While they share many similar features, they can be vastly different. In this lesson, we will learn how rivers and streams form, transport sediment, and flood.
8. How Natural Events Change Habitats
Natural events, like earthquakes, volcanic eruptions, landslides and floods, can be very powerful and destructive. In this lesson, we will see firsthand how they can change human and wildlife habitats in both damaging and helpful ways.
