Short Discussion Our planet is unique in several aspects – it has abundance of life, an abundance of water and the surface is constantly renewed by plate tectonics process. But have you ever imagined how it was look like before and how it was different from today? Here is a video link that you have to watch in order for you to understand how the surface of the Earth was started https://www.youtube.com/watch?v=fzhPmemffII What did you learned about the video? Brief understanding is acceptable ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ ___________________________________________________________________________________________________

Earth is about 4.6 billion years old, approximately one-third of the age of the universe. According to the Nebula Theory, it was formed at the same time as the other members of the solar system by accretion from the solar nebula -- gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system

During its billion years of evolution, Earth has gone through a series of major biological and geological changes. Geological events such as volcanic eruptions, collisions of plates boundaries, creation of mountain ranges and sea beds and took place the shape of the planet which it became oblate spheroid and not a perfect circle in shape and heres behind a theory of the creation of the surface of the Earth --- The Plate Tectonics Theory Plate Tectonics is the theory that the Earth’s lithosphere(the land part of the Earth) is composed of a mosaic of rigid plates that are relative motion. Plate tectonics affects humans in several important ways such as earthquakes, volcanism, induces recycling of elements between the geosphere and biosphere and causes mountain-building. Earth without plate tectonics would be hard to imagine. In other words, the Earth would be a much different place and without these events, our planet is not like what we seen it from today. Earth was believed by a scientist named Alfred Wegener that about 1,100 million years ago, there was a supercontinent named Rodinia, which predated Pangaea. During the Late Triassic Period, Pangaea began to break up into two smaller supercontinents called Laurasia(northern) and Gondwanaland(southern). Starting at about 15 Mya, Laurasia drifted sounthward until it crushed into Gondwanaland about 425 Mya. During the history of Pangaea’s formation, the now known North America smashed into northwestern Africa, forming a vast mountain range. And from that, it began to crashed the other plates(continents) and it has formed the northen Europe and Pangaea began to break forming a valley called Atlantic Ocean. The Continental drifting continues in the Jurassic Period, through the Cretaceous Period, and through the Cenozoic Era and by 100 MYA, all the present continents and oceans had been formed. Scientist believed that the

crustal plates are still drifting until today and also predicted 250-300 million years ago from now on, the seven continents will move toward each other again, reforming the historical Pangaea because it is a cycle

process. It is like a mosaic of plates considered to be a JIGZAW PUZZLE that from the day today, it will be back to its original form.

Short Discussion What is Plate Tectonics Theory?  The Earth is broken into large Plates.  The size and position of Plates change.  Plate edges colliding - geologic activity  Creation and separation of continents Question: How are the following events happened in the theory of Plate Tectonics? THE MECHANISMS OF PLATE TECTONICS Lots of mechanisms that cause the plates to move have been proposed (and rejected) although most geologists accept one idea as the most likely mechanisms for plate tectonics: THE CONVECTION Question: What is your understanding about convection? Convection is _________________________________________________________________________________________________ __________________________________________________________________________________________________________________________ Let’s us look inside the Earth. We know that it is really hot most likely in the inner core and it is being considered as the source of the internal heat of the Earth: those internal heats became sources of different energies, regulated, manufactured and used by us for everyday living. BUT, that internal heat comes from inside the Earth causes other events due to changes of the structure and creation of new forms in the lithosphere of our planet SUCH AS:  Earthquakes & Volcanoes  Mountains  Deep ocean vents – site of creation of life Note: Plates are driven by cooling of Earth (convection). Gravity provides additional force to move plates.  Convection is like a boiling pot. Heated soup rises to the surface, spreads and begins to cool, and then sinks back to the bottom of the pot where it is reheated and rises again.  Convection moves hot material from Earth’s interior up to the surface to cool; gravity with convection draws the dense material back into the hotter interior; this is an efficient way for our planet to cool. In kid vernacular, “heat rises, gravity destroys.” The mobile rock beneath the rigid plates is believed to be moving in a circular manner somewhat like a pot of thick soup when heated to boiling.

This cycle is repeated over and over to generate what scientists call a convection cell or convective flow. Convective flow can be observed easily in a pot of boiling soup, the idea of such a process stirring up

the Earth s interior.

This cycle is resulted to : CREATION OF BOUNDARIES - leads of the continuous separation and movement of the Earth’s crust Three Basic Types of Plate Boundaries Direction : Using your hands, understand the following illustrations below to understand the concept of the different type of boundaries.

CONVERGENT

DIVERGENT

TRANSFORM

CONVERGENT BOUNDARIES - Places where plates crash or crunch into each other. All the folding and bending makes rock in both plates break and slip, causing earthquakes. Rock deep in the Earth melts, builds up pressure causing volcanoes.

DIVERGENT BOUNDARIES - Places where plates come apart are called divergent boundaries. When Earth's brittle surface layer is pulled apart, it breaks along parallel faults that tilt slightly outward from each other. As the plates separate along the boundary, the block between the faults cracks and drops down into the soft, plastic interior. The sinking of the block forms a central valley called a rift. Magma (liquid rock) seeps upward to fill the cracks. In this way, new crust is formed along the boundary TRANSFORM BOUNDARIES - Places where plates slide past each other are called transform boundaries. The most famous transform boundary in the world is the San Andreas fault. Los Angeles will not crack off and fall into the ocean as popularly thought, but it will simply creep towards San Francisco at about 6 centimeters per year. In 16 million years, the plates will have moved so much that Los Angeles will be north of San Francisco!

Activities : I. Write a reaction paper base from “Kapuso Mo, Jessica Soho: Lumang bayan ng Pantabangan, muling lumitaw!” content last August 3, 2020. Do you think, PLATE TECTONICS THEORY would be the hidden explaination of these events from that old barrio of Pantabangan? Please use another paper for your reaction paper.

Describe the internal structure of the Earth and processes beneath

Short Discussion The Earth has layered structures which are important for understanding the PLATE TECTONICS THEORY. Studying the Earth’s interior can help us understand earthquakes, volcanoes, and more about the Earth’s natural processes. Are you still familiar on the different layers of the Earth which plays the important part on how the Earth was look like from today? Here’s a video link on how the different plates move due to geological process of the internal structures of the Earth. https://www.youtube.com/watch?v=ryrXAGY1dmE Answer the guide question below: Do you think why the Earth layered structures are really important in understanding the Plate Tectonics Theory? ___________________________________________________________________________________________________ ___________________________________________________________________________________________________ ___________________________________________________________________________________________________

From the Ancient Greek geo means "earth" and logia mean "study of”. Geology is an earth science comprising the study of Earth interior and composition. The Earth has layered structures namely the crust, mantle, inner core and outer core. CRUST - It is the solid (land part/lithosphere) and thinnest outermost layer part of the Earth. Volcanic activity is continually adding mass to it. It is made up of plates called as TECTONIC PLATES. These plates are continuous in constant motion due to the convection currents in the second layer of the Earth. There are two types of crust; the CONTINENTAL CRUST and OCEANIC CRUST • • •

CONTINENTAL CRUST- the relatively thick part of the earth's crust that forms the large landmasses OCEANIC CRUST -A thin layer of rock separates the Earth's oceans from the hot mantle beneath them

CONTINENTAL CRUST (The elevated land mass of the Earth)

OCEANIC CRUST (The landmasses found beneath the ocean)

MANTLE (THE GREAT WALL) - The second inner, thickest and the largest layer of the Earth’s interior. It is thought to be composed mainly of olivine-rich rock. It serves as 85% of the total mass of the Earth of different steady rock materials. It is divided into two: UPPER MANTLE & LOWER MANTLE UPPER MANTLE – The rocks in this layer are cool and brittle. Rocks in this layer are brittle enough to break under stress and produce earthquakes. LOWER MANTLE – The rocks in this layer are hot and soft (BUT NOT MOLTEN). Rocks are soft in this layer to easily subject to forces of breaking....
