Learning Competency: 1. Describe and relate the distribution of active volcanoes, earthquake epicenters, and major mountain belts to Plate Tectonic Theory Lesson Summary EARTH’S STRUCTURE In the early part of the 20th century, geologists studied the vibrations (seismic waves) generated by earthquakes to learn more about the structure of the earth's interior. They discovered that it is made up of these distinct layers: the crust, the mantle, and the core. TRACE I.D.E. Learning Packet SCIENCE 10 J. Melicio SLP 1 Page 3 of 19 Property of TRACE College Inc.

The picture on the right shows the continents of the earth as they appear today. The picture on the left shows the continents as they appeared long ago – approximately 250 million years ago. How do we know this? In the early 1900s, the German scientist Alfred Wegener noticed that the coastlines of Africa and South America looked like they might fit together. He also discovered evidence that the same plant and animal fossils were found along the coasts of these continents, although they were now separated by vast oceans. In addition, he noticed that geologic formations, like mountain ranges, on the two continents also matched up. In 1915, Wegener published his book, The Origin of Continents and Oceans, suggesting that the earth's continents were once joined together in one large mass. He called the original landmass (or supercontinent) "Pangaea," the Greek word for "all the earth." According to Wegener, over time "Pangaea" split apart and the different landmasses, or continents, drifted to their current locations on the globe. While other scientists of the time vehemently rejected Wegener's ideas, they became the basis for the development of the theory of plate tectonics. The modern plate tectonics theory, which has become widely accepted since the 1960s, states that the earth's outer layer, or lithosphere, is broken into several large slabs called plates. These plates, which hold the continents and oceans, are slowly but constantly moving around the planet. The movement of the plates not only supports our understanding that continents are not fixed and moved over time, but also explains how and why earthquakes, volcanoes, and other geologic events occur.

The correct image, above, is based on a map created by Dr. C. R. Scotese showing what “Pangaea Ultima” might look like. There are seven relatively large plates and a number of smaller ones, including the Philippine plate. The plates move very slowly but constantly, and this movement is called tectonics; thus the theory of moving lithospheric plates is called plate tectonics. Map of Plate Boundaries TRACE I.D.E.

You have to measure the interval to the closest second and then use a Distance-time graph to convert the S-P interval to the epicentral distance. Once you have the epicentral distances, you can draw circles to represent each distance on a map. The radius of each circle corresponds to the epicentral distance for each seismic recording station. Once you have drawn all three circles and located the point where all three intersect, you will have successfully located (triangulated) the epicenter of the earthquake. Plates are large pieces of the upper few hundred kilometers of Earth that move as a single unit as it floats above the mantle. The plates are in constant motion. As they interact along their margins, important geological processes take place, such as the formation of mountain belts, earthquakes, and volcanoes. TRACE I.D.E. Learning Packet SCIENCE 10 J.

These features can be sources of different minerals or can be used for agricultural purposes. For example, we have the majestic and world renowned Mayon Volcano. Because of its activity, it produces fertile slopes and plains which are used by the locals to grow their crops. Also, found in the northeastern coast of Luzon, we have the Sierra Madre mountain range which is home to many endemic species of flora and fauna. Plate Tectonics Theory is the framework that enable us to understand how and why several features of the Earth continuously change. This describes the events within the Earth that give rise to mountain ranges, volcanoes, earthquake belts, and other features of the Earth’s surface. References 1.

Each plate is slowly moving relative to each other, causing geologic events to happen along their boundaries. Learning Competencies: 1. Describe the different types of plate boundaries 2. Explain the different processes that occur along the plate boundaries Lesson Summary THE 15 MAJOR TECTONIC PLATES As you can see, some of the plates contain continents and others are mostly under the ocean. The type of crust that underlies the continents is called continental crust, while the type found under the oceans is called oceanic crust. Continental crust is thicker — about 20 to 40 miles (35 to 70 km) thick — and usually older than oceanic crust, which is only 4 to 6 miles (7 to 10 km) thick. All the plates have names, usually referring to landmasses, oceans, or regions of the globe where they are located. TRACE I.D.E. Learning Packet SCIENCE 10 J.

All the tectonic plates are constantly moving — very slowly — around the planet, but in many different directions. Some are moving toward each other, some are moving apart, and some are sliding past each other. Because of these differences, tectonic plate boundaries are grouped into three main types. EXAMPLES EXAMPLES EXAMPLES the boundary the boundary the boundary between the between the African between the Pacific Eurasian Plate and Plate and the Plate and the the Indian Plate at Arabian Plate in the Australian Plate, the Himalayas Red Sea crossing New the boundary the boundary Zealand between the Nazca between the Pacific the boundary Plate and the South and Antarcsc Plates between the Pacific American Plate Plate and the North along the west coast American Plate in of South America California A convergent A divergent boundary boundary marks A transform boundary occurs where two plates that occurs where two plates are are moving two plates slide pushing toward apart from each past each other. each other. other.

FOR ACADEMIC PURPOSES ONLY, NOT FOR SALE www.tracecollege.edu.ph (049) 536-3944  Most major geologic events occur at the boundaries between tectonic plates, where huge, massive pieces of the earth's crust interact. Each kind of plate boundary is associated with particular events, so if you know about the movements taking place at a plate boundary, you can often predict what's likely to occur there — volcanoes, earthquakes, mountains, trenches — in the future! At convergent boundaries, tectonic plates collide with each other. The events that occur at these boundaries are linked to the types of plates — oceanic or continental — that are interacting. CONVERGENT BOUNDARIES At convergent boundaries, tectonic plates collide with each other. The events that occur at these boundaries are linked to the types of plates — oceanic or continental — that are interacting. 1. An oceanic plate collides with a continental plate Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone. TRACE I.D.E. Learning Packet SCIENCE 10 J. Melicio SLP 1 Page 13 of 19 Property of TRACE College Inc. FOR ACADEMIC PURPOSES ONLY, NOT FOR SALE www.tracecollege.edu.ph (049) 536-3944  As the oceanic crust sinks, a deep oceanic trench, or valley, is formed at the edge of the continent. The crust continues to be forced deeper into the earth, where high heat and pressure cause trapped water and other gasses to be released from it. This, in turn, makes the base of the crust melt, forming magma. The magma formed at a subduction zone rises up toward the earth's surface and builds up in magma chambers, where it feeds and creates volcanoes on the overriding plate. When this magma finds its way to the surface through a vent in the crust, the volcano erupts, expelling lava and ash. An example of this is the band of active volcanoes that encircle the Pacific Ocean, often referred to as the Ring of Fire. 2. Collision of two oceanic plates A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Examples include the Mariana Islands in the western Pacific Ocean and the Aleutian Islands, off the coast of Alaska. Since the collision and subduction of plates is not a smooth process, large, powerful earthquakes are another phenomenon that result from this type of interaction. Earthquakes generated in a subduction zone can also give rise to tsunamis. A tsunami is a huge ocean wave caused by a sudden shift on the ocean floor, such as an undersea earthquake. If the wave reaches land, it can cause incredible destruction, like the Asian Tsunami, which killed more than 200,000 people in 11 countries across the Indian Ocean region in December 2004. 3. Collision of two continental plates Because the rock making up continental plates is generally lighter and less dense than oceanic rock, it is too light to get pulled under the earth and turned into magma. Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges. TRACE I.D.E.

Containing the highest mountain peaks in the world and traversing the modern-day countries of India, Pakistan, China (Tibet), Bhutan, and Nepal, the Himalayas were formed by the collision of the Indian and Eurasian Plates. This process began after the breakup of Pangaea, when India became an island continent and began traveling northward toward Asia. The island of India slammed into Asia about 40 to 50 million years ago near modern-day Tibet, crushing and folding the plates to form the Himalayan mountain range. Its best known peaks, Mount Everest and K2, are among several that measure over 8,000 meters (26,000 feet) high at their summits. Since the Indian Plate is continuing in its northward movement into Asia, the Himalayas continue to grow higher each year by small amounts (5 to 20 mm or 1 inch per year). DIVERGENT BOUNDARIES At divergent boundaries, tectonic plates are moving away from each other. But if these huge masses of crust are moving apart, what happens in the space left between them? 1. Seafloor Spreading Divergent boundaries in the middle of the ocean contribute to seafloor spreading. As plates made of oceanic crust pull apart, a crack in the ocean floor appears. Magma then oozes up from the mantle to fill in the space between the plates, forming a raised ridge called a mid- ocean ridge. The magma also spreads outward, forming new ocean floor and new oceanic crust. TRACE I.D.E. Learning Packet SCIENCE 10 J. Melicio SLP 1 Page 15 of 19 Property of TRACE College Inc.

This rift is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do volcanoes, which may become increasingly active. Early in the rift formation, streams and rivers flow into the low valleys and long, narrow lakes can be created. Eventually, the widening crust along the boundary may become thin enough that a piece of the continent breaks off, forming a new tectonic plate. At this point, water from the ocean will rush in, forming a new sea or ocean basin in the rift zone. TRANSFORM BOUNDARIES At transform boundaries, tectonic plates are not moving directly toward or directly away from each other. Instead, two tectonic plates grind past each other in a horizontal direction. This kind of boundary results in a fault — a crack or fracture in the earth's crust that is associated with this movement. 1. Faults and Earthquakes Transform boundaries and the resulting faults produce many earthquakes because edges of tectonic plates are jagged rather than smooth. As the plates grind past each other, the jagged edges strike each other, catch, and stick, "locking" the plates in place for a time. Because the plates are locked together without moving, a lot of stress builds up at the fault line. This stress is released in quick bursts when the plates suddenly slip into new positions. The sudden movement is what we feel as the shaking and trembling of an earthquake. The motion of the plates at a transform boundary has given this type of fault another name — a strike-slip fault. The best-studied strike-slip fault is the San Andreas Fault in California. It is located at the boundary between the Pacific and North American plates and runs roughly 800 miles (1,300 km) TRACE I.D.E. Learning Packet SCIENCE 10 J. Melicio SLP 1 Page 16 of 19 Property of TRACE College Inc. FOR ACADEMIC PURPOSES ONLY, NOT FOR SALE www.tracecollege.edu.ph (049) 536-3944  through Northern and Southern California. As the two plates grind past each other — the Pacific Plate moving northwest and the North American Plate moving southeast — the motion produces numerous earthquakes along the fault. While many are small and cause only minor trembling, the San Andreas Fault has also been the site of major events: the 1857 Fort Tejon earthquake, the 1906 San Francisco earthquake and fire, and the 1989 Loma Prieta earthquake. Many scientists believe that the San Andreas Fault is due to unleash another large earthquake — a "big one" — in the coming decades. Application Many of the most dramatic geological phenomena we experience on Earth — volcanic eruptions, earthquakes, tsunamis, and more — are caused by the slipping, sliding, and colliding of tectonic plates. For example, the red-hot lava and plumes of ash spewing out of a volcano in the Philippines, an undersea earthquake in the Indian Ocean that spawns a tsunami that crashes into Indonesia, and the Himalayan Mountains that grows taller every year.
