Plate Tectonics - Earth Like a Puzzle - Children learn about plate tectonics, earthquakes, and volcanoes at this site in Scripps Institution of Oceanography
by Nan Criqui Most people know that Earth is moving around the Sun and that it is constantly spinning. But did you know that the continents and oceans are moving across the surface of the planet? Less than 100 years ago, many scientists thought the continents always had been the same shape and in the same place. Putting the Puzzle Together... Related:  Plate TectonicsGeografiGeografi

Biosphere: Erosion Erosion is the process that breaks things down. As far as we're concerned, erosion is the breakdown of the continents and the land around you. The overall effect of breaking down and weathering the land is called denudation. Denudation is the process of erosion. In nature, large things are broken down into smaller things. Erosion is an easy idea to understand. Things don't just disappear. Mass wasting can happen two ways: 1) mechanical, similar to breaking a rock with a hammer; and 2) chemical, similar to pouring acid on a rock to dissolve it. A surefire way to tell what is happening is to check the color of the rock. Erosion happens at the tops of mountains and under the soil. Or search the sites for a specific topic.

David Rumsey Historical Map Collection | The Collection ▶Layers of the Earth Rap Plate Tectonics Lesson Summary Overview According to the theory of plate tectonics, Earth's crust is composed of a number of individual plates that change shape and position over time. The ocean floors are continually moving — spreading from the center, sinking at the edges, and being regenerated.Convection currents beneath the plates are responsible for plate movement.The source of energy responsible for generating the heat and convection currents that move the plates is most likely radioactivity deep in Earth's mantle. In this lesson, students are introduced to the theory of plate tectonics and explore how the theory was developed and supported by evidence. Objectives Understand how Earth is dynamic and how moving plates form ocean basins, mountain ranges, islands, volcanoes, and earthquakesIdentify the three general categories of plate boundaries recognized by scientists: convergent, divergent, and transformUnderstand how the theory of plate tectonics was developed and supported Grade Level: 6-8 1. 2.
