plate tectonics Definition, Theory, Facts, & Evidence Britannica
Key points: Earth's lithosphere, or outermost shell, is broken up into large pieces called tectonic plates. These plates move slowly over the asthenosphere, a layer of softer rock below the lithosphere. On average, tectonic plates move a few centimeters per year. The place where two plates meet is called a plate boundary.

A Map of Tectonic Plates and Their Boundaries
The San Andreas Fault Zone is not the only active transform plate boundary with U. S. National Park Service sites. Southeast of Florida, the Caribbean Plate is sliding east-northeast about 0.8 inches (2 centimeters) per year relative to the North American Plate. Both plates are capped by oceanic crust.
What Causes Tectonic Plates To Move? WorldAtlas
Plate tectonics is the theory that Earth's outer shell is divided into large slabs of solid rock, called "plates," that glide over Earth's mantle, the rocky inner layer above Earth's core..
Theory of Plate Tectonics CK12 Foundation
On the diagram below, draw arrows in the boxes to indicate the direction of plate movement. Then, draw the motion of the "magma.". - The Pacific crustal plate moved over a hot spot during the process of plate tectonics. The hot spot stayed still and made a line (a series) of mountains in the ocean, which we call the Hawaiian Islands. The.
A Shift to Plate Tectonics The Emergence and Evolution of Plate
Plate boundaries can be located by outlining earthquake epicenters. Plates interact at three types of plate boundaries: divergent, convergent and transform. Most of the Earth's geologic activity takes place at plate boundaries. At a divergent boundary, volcanic activity produces a mid ocean ridge and small earthquakes.
Plate tectonics 101โwhat happens when plates move toward each other
What are the different types of plate tectonic boundaries? There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey. Download image (jpg, 76 KB).
Volcanoes and Plate Tectonics
Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth's subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.

Plate tectonics Seafloor Spreading, Continental Drift, Subduction
The 2006 U.S. Geological Survey map of tectonic plates show 21 of the major plates, as well as their movements and boundaries. Convergent (colliding) boundaries are shown as a black line with teeth, divergent (spreading) boundaries as solid red lines, and transform (sliding alongside) boundaries as solid black lines.
How Do Tectonic Plates Move? WorldAtlas
Plate tectonics is a theory about how Earth's lithosphere is divided into a series of rigid plates; and, how movements of these plates produce earthquakes, volcanoes, ocean trenches, mountain ranges, and more.

Plate tectonics GEOGRAPHY MYP/GCSE/DP
The tectonic plates map of the Earth shows where mountain building, volcanoes, and earthquakes have occurred. how many tectonic plates are there? There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
Evolution of the Theory of Plate Tectonics Owlcation
The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways.
Plate Tectonic Types Divergent, Convergent and Transform Plates
plate boundaries causes earthquakes, volcanoes , and mountain building. Identify convergent boundaries, including subduction and collisions, as places where plates come together. Identify divergent boundaries, including rifts and mid-ocean ridges , as places where plates separate. Explain transform boundaries as places where adjacent plates shear
Plate Boundaries Vector Illustration Labeled Tectonic Movement
Introduction to plate tectonics Google Classroom About Transcript Earth's lithosphere is broken up into tectonic plates, which move slowly over time. Evidence like matching coastlines and same-species fossils on different continents support this. A plate boundary is where two tectonic plates meet.

Please feel free to use these illustrations in any way that will enhance your teaching. And, if you have time, draw them once for me. Thank you to Angela King for producing the several hundred animation frames.
2 Schematic representation of the three types of plate boundaries
National Geographic MapMaker: Plate Boundaries In some ways, Earth resembles a giant jigsaw puzzle. That is because its outer surface is composed of about 20 tectonic plates, enormous sections of Earth's crust that roughly fit together and meet at places called plate boundaries.
