Facts About Earthquakes

3rd - 6th Grade Textbook

L1 Earthquakes

Facts about earthquakes are found in every lesson of our Level 1 Earthquakes textbook. There are twelve lessons in the book. These are some of the lesson titles included in the book: Earthquake Waves, Earthquake Zones, Normal and Reverse Faults, Transform Faults, Mercalli Scale and the Richter Scale. 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 kids 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: Traveling Waves, Can you Hear That Wave, Richter Scale, Big Harbor Waves and Survival Kits. Each of these activities are designed to be created by students with materials commonly found around the home or in the neighborhood.

Facts about earthquakes

Facts about earthquakes that occur on Earth. The crust of the Earth is in constant motion. Large crustal plates are moving in different directions around the Earth at about the speed our fingernails grow. Earthquakes on the edges of these plates. Approximately 800,000 earthquakes occur each year that are very small. Once every five to ten years a great earthquake occurs that can level an entire city.

Why do earthquakes happen?

Earthquakes are caused by Earth’s tectonic plates moving around the Earth. The San Andreas Fault that runs through California is master fault where the North American Plate and the Pacific Plate are slipping past each other. This fault produces large and small earthquakes as the rocks break part due to the moving plates. In the Basin and Range area of the United States normal and reverse faults have formed as the plates move apart and smash together. Each of these faults create earthquakes when a rupture occurs and the rocks break apart. Each of these facts about earthquakes explain why they occur more often in certain areas of our planet.

Alaska 1964 earthquake

The Alaska 1964 earthquake occurred when the North American Plate slipped over the Pacific Plate. The area where the earthquake occurred is a subduction zone. The two plates were locked prior to the earthquake. The pressure on the rocks in the earthquake zone ruptured. The North American Plate moved approximately 9 meters during the rupture and affected 100,000 square miles (250,000 km2). Most of the people killed during the earthquake died as a result of tsunamis that swept over low-lying areas including Hawaii.

Earthquake scale

Today there are two major scales that are used to describe earthquakes. The Richter scale was devised in the 1930s to measure earthquakes in California. After the 1960 Chilean earthquake and the Alaska 1964 earthquake a new scale was devised. The Moment Magnitude Scale is used when reporting large megathrust earthquakes like the Great Alaskan Earthquake. The Richter scale is used for small earthquakes that measure less than 9.0 on the scale. These facts about earthquakes are important to know if you live in an area prone to earthquakes.
