The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

1. The Dynamic Earth: Internal & External Forces that Shape Earth's Surface

There are many geologic processes that shape the surface of the Earth. Not only do they build and destroy a variety of landscapes, but they also give us clues to the interior of the Earth and the forces that exist there.

The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere

2. 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.

The Internal Layers & Structure of the Earth

3. The Internal Layers & Structure of the Earth

While the Earth feels pretty solid, it's actually mostly liquid. Of course, the only reason we know all this is because of atomic weapons! As this lesson shows, studying the makeup of the Earth has been explosive at times.

What are Convection Currents? - Definition & Examples

4. What are Convection Currents? - Definition & Examples

This lesson will define convection, explain how it works, and describe how convection creates currents. We will also go through some examples of convection in the world around us: campfires, weather systems, and convection in the earth's mantle.

Formation of the Earth: Theories

5. Formation of the Earth: Theories

In this lesson, the theory of how the planet Earth formed will be discussed. This includes looking at how it differentiated into three layers, how it formed its atmosphere, water, and land features, and how it continues to evolve today.
