About This Chapter
The Earth, Weather & Erosion - Chapter Summary
Use this chapter to recall important facts about the Earth, weather, and erosion. These lively video lessons look at the surface of the Earth, contributors to erosion, the four types of water erosion, weather types, and scientific observations. By the close of this chapter, you should be ready to do the following:
- Describe the basics of weathering and erosion
- Compare wind, soil, water, and beach erosion
- Explain the function of weather maps
- Identify the meaning of different weather symbols
- Define how changes in natural phenomena can be observed over time
- Point out how to investigate water and air temperature variations
- Establish ways to use index fossils as time indicators
The self-assessment quizzes attached to every lesson we offer will challenge you to answer questions about definitions, major terms, key concepts, and more. These quizzes can be repeated as often as needed and include links back to the lesson, making it easy to review topics that you are unclear on. At the end of the chapter is a comprehensive exam that allows you to make sure you understand everything covered here.
1. Erosion & Weathering Lesson for Kids
The Earth's land is always changing. Two processes that contribute to those changes are weathering and erosion. In this lesson, you will learn all about these processes, including how they are different and how they affect the planet you call home.
2. Wind Erosion Lesson for Kids
Although we can't see it, wind is a powerful force that affects the Earth's surface all the time. In this lesson, you will learn what wind erosion is, what types there are, and some of the awesome features created by wind erosion.
3. Soil Erosion Lesson for Kids
When something erodes, it wears away. In this lesson, you'll learn what causes soil to erode, what soil erosion looks like, and what can be done to control it.
4. Water Erosion Lesson for Kids
In this lesson, you will learn how Mother Nature uses 4 types of water erosion to move soil and particles from one area to another. You will also find out how humans cause water erosion and the effect it has on Earth.
5. Beach Erosion Lesson for Kids
This lesson discusses the causes and effects of beach erosion. You will learn what causes beach erosion, how human activity affects it, and how coastal areas try to prevent it.
6. Weather Maps Lesson for Kids
Understanding how to use weather maps can help you plan for your day and week. This lesson describes what weather maps are, why they are important, and how to read them, and we'll explore different types of weather maps.
7. Weather Symbols Lesson for Kids
What's the weather like? To check the weather, you can look at a weather map, but you will need to know some symbols. Learning how to use a weather map to spot sunny, warm weather or rainy, dangerous weather can really help you out if you want to take a trip.
8. Observing Changes in Natural Phenomena Over Time
Science is all about observing changes - even when they are difficult to observe. Learn about how scientists observe changes in natural phenomena over time. Test your knowledge after the lesson with a quiz.
9. Investigating Variations in Air & Water Temperatures
Seasons come and season go, with each one bringing a change in temperature. In this lesson, learn how to collect qualitative and quantitative data related to seasonal variations in air and water temperatures.
10. Relative Dating with Fossils: Index Fossils as Indicators of Time
You may already know how to date a fossil with a rock. But did you know that we can also date a rock with a fossil? Watch this video to find out how we use index fossils to establish the relative ages of rocks.
