Earth Science Facts

3rd - 6th Grade Course

Level 1 Course 1

Our Course 2 is filled with Earth Science facts. The course includes four  textbooks: Earth Science, Rock Cycle, Volcanoes and Earthquakes. The four textbooks each have twelve lessons and are designed for upper elementary students. This course is designed to be completed in one semester by students who finish three lessons per week. Each lesson in the textbooks contains 2-3 pages of written material, quiz and elementary science activity.

Video Lessons

Video lessons include information on the rock cycle that is not included in the textbook. Myrna introduces each lesson and gives this additional background information on the rock cycle during each video lesson.

Elementary Science Activities

The kids science activities are fun and easy to do. They also increase a student’s understanding of the earth science facts that are taught in the lesson. Each of the activities are designed to be created by students with materials commonly found around the home or in their neighborhood.

Earth Science Facts

Do you know these interesting Earth Science facts? Seismic waves were used in the discovery of the Moho boundary, outer core and inner core. Great towering stratovolcanoes form on the continental side of subduction zones. The great shield volcanoes of the Hawaiian Islands formed over a persistent hot spot in the middle of the Pacific Plate.

You can walk down rift valleys and step on two tectonic plates in Iceland. Planet Earth is part of the Solar System that circles the Sun. All life on our planet lives at the bottom of an ocean of air that is held to our planet by gravity.

Facts about the Rock Cycle

The rock cycle contains three major groups of rocks. Igneous rocks formed when molten rock (magma) cools. Intrusive, plutonic, lava, and tephra are examples of different types of igneous rocks. Sedimentary rocks cover 75% of the Earth’s surface. The major types of sedimentary rocks are shale, sandstone, limestone and coal. All metamorphic rocks contain recrystallized minerals. Slate is a low-grade metamorphic rock. Gneiss is a high-grade that forms under extreme heat and pressure.

What are volcanoes?

Volcanoes are mountains of fire. Beneath volcanoes molten rock (magma) collects in magma chambers. The hot magma is buoyant and moves up through the throat of the volcano where it erupts onto the Earth’s surface. Volcanoes come in many shapes and sizes. Some are cone shaped, other form a shield shape, some are domes and others are small steep-sided mountains. Learn more Earth science facts by reading our textbook on volcanoes.

Facts about earthquakes

Earth Science facts about earthquakes. Pressure inside rocks along a fault line build up pressure in the rocks until them break triggering an earthquake. Every earthquake produces P waves and S waves. Ninety percent of all earthquakes are generated at tectonic plate boundaries. Large earthquakes occur on average about every four to five years. Love waves and Rayleigh waves are earthquake waves that travel only along the surface of the Earth after large earthquakes.
