Transform Plate Boundary A transform boundary is where plates slide past one another. Most transform faults are found on the ocean floor where they offset the active oceanic ridges. At the red star, the motion of the plate to the top appears to be to the left, whereas the plate to the bottom appears to move to the right.
The edges of the plates are called plate boundaries. The Earth has 7 major plates (Africa, Antarctica, Australia, Eurasia, North America, South America and Pacifica) and several minor ones (Adria, Arabia, Caribbean, Nazca, Philippines and others). Most of the plates are composed of continental and oceanic lithosphere. These plates
Intense geologic activity occurs at plate boundaries where plates: Move away from one another. Move past one another. Move towards one another. The theory of plate tectonics is widely accepted by geologists today because it explains so many of the Earth’s features.
As students become aware of plate movements, they begin to identify patterns that set the stage for deeper understanding of a very complex topic. The activity uses a simple “Where’s Waldo” approach to identify tectonic symbols on a laminated World Plate Tectonic map. Objectives.
Plate Tectonics explains the movements of the earth’s crust and the different ways by which that movement occurs. Students will learn the three types of boundaries and be able to provide examples of each. They will also discover and identify major continental plates of the earth.
The movement of the plates, and the activity inside the Earth, is called plate tectonics. Plate tectonics cause earthquakes and volcanoes. The point where two plates meet is called a plate boundary. Earthquakes and volcanoes are most likely to occur either on or near plate boundaries.
• Compare and contrast the three types of plate boundaries and describe the three main ways boundaries interact: spreading apart, coming together, and sliding past one another. • Describe the processes that occur at divergent boundaries and explain how new ocean floor is created.
