What Are Volcanoes?

3rd - 6th Grade Textbook

L1 Volcanoes

L1 Volcanoes textbookL1 Volcanoes

Students learn what are volcanoes and how they form in our Level 1 Volcanoes textbook. The book contains information about volcanoes and their formation in each of the 12 lessons. These are some of the lesson titles included in the book: Four Types of Volcanoes, Four Types of Eruptions, Craters and Calderas, Plate Tectonics, Pacific Ring of Fire, Submarine Volcanoes and Hawaiian Islands. Each lesson contains 2-3 pages of written material, a quiz and a kids science activity.

The textbooks are designed for upper elementary school students. Each textbook can be completed in one month by students who finish three lessons per week. A semester of Earth Science credit can be earned by students completing one of the Level 1 courses. Students wishing to earn a year of Earth Science credit should complete both Level 1 courses.

Video Lessons

Myrna Martin introduces each lesson in the textbook on a video that can be purchased with our complete kits, packages and courses. Myrna covers not only the main points in the lesson she also includes extra information on the topic that is not contained in the written material.

Elementary Science Activities

The elementary science activities are fun and easy to do. They also increase a student's understanding of the information taught in the lesson. Examples of the activities include: Circle Eruptions, Hot Spot Volcano, Pumice Eruptions, Miniature Volcano and Mapping Volcanoes. Each of these activities are designed to be created by students with materials commonly found around the home or in their yard.

What are volcanoes?

What are volcanoes and where do they form? Volcanoes form in subduction zones, where crustal plates are separating on ocean floors and over hot spots. Each of these areas create different types of volcanoes. Subduction zones produce towering composite volcanoes on the continental side of the subduction zone. Crustal plates on ocean floors produce long chains of mountains when lava oozes out onto the ocean floor. Hot spot volcanoes form above places on the Earth’s crust when magma (molten rock) forms in the upper mantle that feeds volcanoes that form in the ocean and on land.

Facts about what are volcanoes

Have you ever asked yourself what are volcanoes because volcanoes come in many shapes and sizes. Volcanoes on the floors of the world’s ocean form when crustal plates are separating and lava oozes out onto the ocean floor forming pillow basalt. Pillow basalt covers all the ocean floors. The Hawaiian Islands are great shield volcanoes that have formed over a hot spot in the middle of the Pacific Plate. Stratovolcanoes form in subduction zones when a continental plate and an oceanic plate collide. The oceanic plate melts as it is forced beneath the continental plate forming towering volcanoes like Mt. Rainier and Mt. Fuji.

What is igneous rock?

Igneous rock forms when molten rock cools either beneath or above the Earth’s surface. All igneous rock that cools underground forms interlocking crystals that are visible to the naked eye. Granite is a common form of intrusive rock. Molten rock with enough expanding gases in the magma erupts either in a lava flow or is blown out of a volcano during a volcanic eruption.

What are volcanoes that form quiet eruptions

Submarine volcanoes and shield volcanoes of basalt create quiet eruptions. Some eruptions are quiet enough that they and can be observed close up. The Hawaiian Islands have quiet eruptions. Kilauea volcano has quiet eruptions that people often come to watch.

What is tephra?

All igneous rocks that form during a volcanic eruption and are airborne for a period of time are tephra. Cinders/scoria are small pieces of basalt rock that formed when lava was blown out of a crater. Basalt that contains enough dissolved gases in the magma creates cinder cones. Cinder cones are volcanic mountains created almost entirely of pieces of lava about the size of a walnut. Pumice forms in explosive eruptions of rhyolite that are extremely violent and are associated with supervolcanoes. Pumice is the only rock that floats.

Homeschool Science Materials

Our Earth Science curriculum has been recommended by a number of authors including:

  • More Charlotte Mason Education - A Home Schooling How-To Manual by Catherine Levison

All of our science materials have been used by homeschooling families throughout the United States since 1998.

Recommended by AFMS Junior Chair

Ring of Fire Science materials were recommended by Jim Brace-Thompson of the American Federation of Mineralogical Societies.  He found our materials contain a wealth of information for the junior members of the society. He wrote that our books are beautifully designed and illustrated with easy-to-follow instructions for kids.
