Earthquakes and Volcanoes: Evidence of Earth's Inner Layers

1. Earthquakes and Volcanoes: Evidence of Earth's Inner Layers

The interior layers of the earth are not able to be observed directly, so scientists need to rely on other information to learn about it. S waves, P waves, and magma from volcanoes and earthquakes give a glimpse at the layers of the earth by providing data that can be built into a model of the earth.

Using the Richter Scale to Measure Earthquakes

2. Using the Richter Scale to Measure Earthquakes

In this video lesson, you will learn about earthquake magnitude and how it is measured. You will also learn how that relates to the amount of energy released during an earthquake, as well as how common different magnitude earthquakes are around the world.

Destruction Caused by Earthquakes

3. Destruction Caused by Earthquakes

Earthquakes are well-known for their damage and destruction, and in this video lesson you will learn about the different types of damage that these dangerous natural disasters can cause.

Volcanic Eruption: Gases Released & Their Effects

4. Volcanic Eruption: Gases Released & Their Effects

Volcanic eruptions emit water vapor and toxic gases into the atmosphere. Learn about the gases emitted from an erupting volcano, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid and carbon monoxide and their effects in this video lesson.

What is Volcanic Ash? - Definition, Uses & Effects

5. What is Volcanic Ash? - Definition, Uses & Effects

In this lesson, we'll cover what volcanic ash is and how it's made. We will also go over uses for volcanic ash, as well as the positive and negative effects of this substance.
