What I Need to KnowUnit IModule 8(Week 8)Most Essential Learning CompetencyS10ES-Ia-j-36.6 enumerate the lines of evidencethat support plate movementTHE THEORY OF PLATE TECTONICSWhat this module is about What causes tectonic plates to move? The Plate Tectonic Theory providedan explanation about the movement of the lithospheric plates.The theory of plate tectonics states that the Earth's solid outer crust, thelithosphere, is separated into plates that move over the asthenosphere, the moltenupper portion of the mantle. Oceanic and continental plates come together, spreadapart, and interact at boundaries all over the planet.There is variety of evidence that supports the claims those platetectonics accounts for (1) the distribution of fossils on different continents, (2) theoccurrence of earthquakes, and (3) continental and ocean floor features includingmountains, volcanoes, faults, and trenches.Convection current is a process which involves the movement of energy fromone place to another. The convection currents tend to move a fluid or gas particlesfrom one place to another. These are created as a result of the differences occurringwithin the densities and temperature of a specific gas or a fluid.In this module, we will study thoroughly the framework that will enable us tounderstand how and why several features of the Earth continuously change. Thistheory is what we call “Plate Tectonics.” This describes and enumerates the lines ofevidence that support plate movement.ContentPlate Tectonic TheoryConvection Current7

In this module, you should be able to:1. Enumerate the lines of evidence that support plate movement.2. Explain what causes the tectonic plates to move.3. Give the importance of the creation of convection current underneath theearth.Here is a simple guide for you in going about the module:1. Read and follow instructions carefully.2. Read each lesson and do activities that are provided for you.3. Activities and/or exercises are given to deepen your understanding of theconcept and to develop your skills. Take time in doing this.4. Take note of important ideas and points for clarification.5. Do not forget to answer the assessment and see how much you have learned.What I KnowMultiple Choice. Choose the best answer.1.

The strength of the magnetic field I slightly stronger than usual.d. The strength of the magnetic field is slightly weaker than usual.2. What is the character of magnetic anomalies on the seafloor?a.

What’s InLearning is fun!Plate Tectonic TheoryGeologists have hypothesized that the movement of tectonic plates isrelated to convection currents in the earth's mantle. Tremendous heat and pressurewithin the earth cause the hot magma to flow in convection currents.These currents cause the movement of the tectonic plates that make up the earth'scrust.The Plate Tectonic Theory provided an explanation about the movement ofthe lithospheric plates. This theory evolved from the two former theories and wasdeveloped during the first decades of the 20th century.The Earth’s lithosphere is divided into several plates. These plates ride overthe weak asthenosphere. There are three types of plate movements – separation oftwo plates (divergent), collision of two plates (convergent), and sliding past eachother (transform).What facilitates the movement of the plates?Heat is produced in the core that produces convection in the mantle. Thisconvection causes the plate to move around. Where convection currents divergenear the Earth’s crust, plates move apart. When convection currents converge,plates move towards each other. The movement of the plates, and the activity insidethe Earth, is called the theory of plate tectonics.Convection CurrentMantle convection drives plate tectonics. Hot material rises at mid-oceanridges and sinks at deep sea trenches, which keeps the plates moving along theEarth’s surface.Mantle convection is the very slow creeping motion of Earth's solidsilicate mantle caused by convection currents carrying heat from the interior to theplanet's surface. The Earth's surface lithosphere rides atop the asthenosphere andthe two form the components of the upper mantle.10
