Ch 26: Basics of Earth Science

About This Chapter

Examine the forces that drive the formation of volcanoes, wind and current patterns and more in this chapter titled Basics of Earth Science. Use the video and other lessons to enhance your knowledge and the lesson quizzes to test your memory.

Basics of Earth Science - Chapter Summary

The lessons in this chapter review the basic forces that build up and break down Earth's landforms. You will brush up on the how weathering and erosion differ and how each impacts the formation of rock and soils. The conservation of Earth's water supply and natural resources is also addressed in this chapter, along with the difference between non-renewable and renewable resources. You will also examine the role of solar energy, the effect of solar radiation and other related processes. The lessons cover the following:

  • Land formations, volcanism, weathering and erosion
  • Types of rocks and the rock cycle
  • Soil profiles and types of soils
  • Definition and impact of solar radiation
  • Explanation of the Earth's geological subsystems
  • How solar energy drives winds, the water cycle and currents
  • Difference between weather and climate
  • Water conservation and the water cycle
  • Description of renewable and non-renewable resources

Ease of access and convenient features are built into this comprehensive study guide chapter. The transcripts that accompany each of the video lessons show key terminology in bold text for easy referral and identification. You can scroll to any part of a video that you want to review and avoid material that is already familiar using the timeline feature, and the links embedded in the lesson quizzes enable you to refer back to a video in order to check an answer or reference a detail.

Landform: Definition & Types

1. Landform: Definition & Types

Read about landforms and their major features. Learn the differences between formations like mountains and hills, valleys and canyons. (Hint: It has to do with their form.)

What is a Volcano? - Definition & Eruptions

2. What is a Volcano? - Definition & Eruptions

Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.

Weathering: Definition & Explanation

3. Weathering: Definition & Explanation

Discover how rocks and minerals are broken down by chemical and mechanical forms of weathering. Learn about some of the many geological formations created by weathering, from large caves to beautiful arches made of rock.

Effect of Erosion and Deposition on Landforms

4. 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.

Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

5. Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks

In this lesson, we will discuss the three main types of rocks and how they are formed. The lesson also gives an introduction into how matter locked in rocks can be cycled through the earth.

What is Soil? - Definition, Structure & Types

6. 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.

Soil Profile: Definition, Development & Types

7. Soil Profile: Definition, Development & Types

Explore the characteristics of soil profiles, their horizons and how they develop. Then you can use this knowledge to help you determine the conditions under which the soil developed and understand the history of the surrounding landscape.

What is Solar Radiation? - Definition & Effects

8. What is Solar Radiation? - Definition & Effects

The sun plays an important role to us on Earth. It provides many things such as light and warmth. But, what is solar radiation and how does it affect us? In this video lesson, you'll learn about solar radiation, how it allows us to survive, and the influence it has on our global climate.

Earth's 4 Major Geological Subsystems

9. Earth's 4 Major Geological Subsystems

When we think of the Earth, we mainly think of the physical land we stand on. The Earth system is much more complex and is comprised of four major geological subsystems that interact to carry out many natural processes.

The Sun as a Source of Energy for Winds, Currents & the Water Cycle

10. The Sun as a Source of Energy for Winds, Currents & the Water Cycle

View this lesson to learn how energy from the sun powers our winds, ocean currents and the water cycle. Learn how the winds, ocean currents and the water cycle react to the energy from the sun.

Weather vs. Climate: Definition, Differences & Effects

11. Weather vs. Climate: Definition, Differences & Effects

This video lesson will guide you in understanding the difference between climate and weather. Discover how they are different but related and how they are the ways you can describe atmospheric conditions on Earth.

The Water Cycle: Precipitation, Condensation, and Evaporation

12. The Water Cycle: Precipitation, Condensation, and Evaporation

This lesson discusses the processes water takes as it moves around the Earth in the water cycle. You'll get an in-depth look at condensation, precipitation, and evaporation.

Water Conservation: How Water Management Can Lead to Sustainable Use

13. Water Conservation: How Water Management Can Lead to Sustainable Use

In this video lesson you will learn about the importance of water conservation. You will also learn about the two ways freshwater is used, and how proper water use can lead to sustainability in agriculture, homes, and manufacturing.

Renewable & Non-Renewable Resources: Definition & Differences

14. Renewable & Non-Renewable Resources: Definition & Differences

We use a variety of Earth's resources, but not all of them will be around forever. This lesson explains the difference between resources that can be regenerated for our use and those that are gone after they are used once.
