1. The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere
Earth is made up of four distinct yet connect spheres. In this video lesson, you will learn about where each sphere is found on Earth, as well as some features commonly found in each.
2. Earth's Internal Layers: Crust, Mantle & Core
Earth is made up of several different layers, each with unique properties. In this video lesson, you will identify each layer of Earth and how it relates to Earth as a whole.
3. Plate Tectonics: A Unified Theory for Change of the Earth's Surface
After many years of trying to solve the mystery of the moving continents, enough data and evidence was collected to develop a unifying theory of how the surface of the earth changes. It's called plate tectonics.
4. What is an Earthquake? - Definition and Components
Earthquakes are well known for the damage and destruction they leave behind. But what is an earthquake? In this video lesson you will learn about what causes earthquakes and the various components involved in these powerful natural disasters.
5. 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.
6. The Processes of Mountain Building
In this video lesson, you will learn about the process of mountain building. You will identify different ways that mountains form, as well as the different types of mountains that result from this process.
7. 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.
8. Wind Action & Effects on the Desert Landscape
Wind is a powerful force that has the ability to shape a landscape. In deserts, wind action changes the landscape through wind erosion in the form of abrasion and deflation.
9. Major Components of the Atmosphere
Our atmosphere is a complex mixture of many different gases. In this video lesson you will identify the major components of Earth's atmosphere as well as how much there is of each.
10. The Structure of the Atmosphere
If you've ever climbed a mountain or been to the beach, you know that the atmosphere is different at different levels. This lesson explains how the structure of the atmosphere is really like a layer cake.
11. Mechanisms of Heat Transfer: Conduction, Convection & Radiation
There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.
12. Global Warming: Atmospheric Causes and Effect on Climate
Global warming is a multifaceted, complex issue. It involves both natural and human causes that can increase the amount of greenhouse gases. This lesson looks at some of the facts about global warming and how they could contribute to climate change.
13. 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.
14. Properties of Ocean Water
Ocean waters are salty and contain minerals and dissolved gases. They also have a high heat capacity and vary in density depending on temperature and salinity. Learn more about the unique chemical and physical properties of ocean water.
15. Ocean Circulation: Patterns & Effect on Climate
The ocean waters are always in motion and as they travel around the globe they carry and distribute heat, which affects the global climate. Learn about the ocean circulation patterns and how they impact the climate.
16. Biosphere: Definition & Explanation
All organisms, from the tiniest bacterium to the largest blue whale, need a place to live. The 'place on Earth's surface where life dwells' is called the biosphere. But what does this really mean? In this lesson, we'll look at the definition of the biosphere and examine how human activity is changing this important part of our planet.
