- Students who struggle with learning disabilities or learning differences, including autism and ADHD
- Students who prefer multiple ways of learning science (visual or auditory)
- Students who have missed class time and need to catch up
- Students who need an efficient way to learn about Earth's surface
- Students who struggle to understand their teachers
- Students who attend schools without extra science learning resources

Students will review:
This chapter helps students review the concepts in an Earth's surface unit of a standard middle school earth science course. Topics covered include:
- Results of erosion and deposition
- Stream valley formation
- Beaches as changing systems
- Effects of rivers and streams on Earth's surface
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.
9. Types of Mountains
There are four types of mountains on Earth. In this lesson, we will cover how each of the types form and what characteristics differentiate them. When you are through, test your knowledge with the short quiz that follows.
10. Indus River: Definition, Location & Facts
The Indus River, which flows through the heart of Pakistan for most of its length, is the 22nd longest river in the world and the 9th longest in Asia. Statistically, it may not sound all that impressive, but this big river has played a crucial role in the history and ecology of the region and continues to be a significant factor today.
