1. The document is a worksheet about plate tectonics that contains questions for students to answer. It covers topics like plate boundaries, how plates move relative to each other, what happens when plates collide, possible causes of plate motion, and how scientists track plate motion. 2. When two tectonic plates with continental crust collide, the continental crust buckles and thickens, pushing the continental crust upward. 3. Plates move due to processes like ridge push from new crust forming at mid-ocean ridges, slab pull from the sinking of old, dense ocean crust into the mantle at subduction zones, and convection currents in the asthenosphere driven by thermal energy from the earth's interior.

1) The document discusses Alfred Wegener's continental drift hypothesis from the early 1900s which proposed that the continents were once joined together in a single landmass called Pangea before breaking apart and drifting to their current locations.
2) Fossil, rock, and climate evidence found on different sides of oceans support Wegener's theory that the continents were once joined.
3) As Pangea broke into pieces, it formed the two supercontinents of Gondwana and Laurasia, which later split into the present-day continents.
Plate Tectonics Review Answers
1. Plate tectonics describes how the Earth's crust is broken into plates that move relative to each other as magma circulates underneath. Plates can divide, collide, or slide past one another at their boundaries.
2. There are three types of plate boundaries: divergent where plates move apart, convergent where they move together, and transform where they slide past each other horizontally.
3. At convergent boundaries, the plates squeeze rock as they move together or subduct one beneath the other.

WHAT IS A PLATE? MAJOR PLATES. Types of Earth’s Crust. Plate Boundary
The document discusses plate tectonics and the key concepts of plate tectonic theory. It describes how the lithosphere is broken into large plates that move over Earth's surface, driven by convection currents in the underlying mantle. It outlines the three main types of plate boundaries - divergent boundaries where new crust forms, transform boundaries where plates slide past each other, and convergent boundaries where plates collide and one slides under the other. It also discusses the evidence that supported the development of plate tectonic theory, such as seafloor spreading and magnetic reversals recorded in oceanic crust.
CONTINENTAL DRIFT THEORY EVIDENCES ppt
The document discusses evidence that supports the continental drift theory proposed by Alfred Wegener. It describes an activity where students reconstruct the supercontinent Pangaea by fitting together continent landmass cutouts. The activity aims to showcase two key evidence: 1) the apparent fit of continents and 2) fossil correlations found across different continents. It also discusses two additional evidence put forth by Wegener: 3) past climate data like glacial striations found in present-day equatorial regions, and 4) correlations between mountain ranges and rock formations between separated continents.
CONVECTION-AND-THE-MANTLE.ppt
The document discusses heat transfer through conduction, convection, and radiation. It explains that convection occurs when heat transfer causes fluid movement within a substance. In Earth's mantle, large convection currents are driven by heat from the core, causing the mantle to circulate. This circulation of the mantle drives the movement of tectonic plates at Earth's surface.
Plate tectonics powerpoint
Plate tectonics refers to the theory that the Earth's crust is divided into plates that move around on the mantle. There are 12 major plates that collide, pull apart, or scrape against each other, causing deformation of the crust and creating characteristic geological features. The driving force behind plate tectonics is convection currents in the mantle, where hot material rises and cools, moving the plates in the lithosphere. There are three types of plate boundaries: divergent, where plates move apart; convergent, where they collide; and transform, where they scrape past each other.

Plate movement ppt
This document provides an overview of plate tectonics and the evidence that supports the theory. It discusses how early scientists like Alfred Wegener proposed that continents move over time (continental drift). Wegener noticed matching land features and fossil evidence between continents. Later, Harry Hess confirmed Wegener's ideas by discovering that new crust forms at mid-ocean ridges, providing evidence of sea-floor spreading as plates move apart. Convection currents in the mantle caused by heat from the Earth's core are now understood to drive the movement of tectonic plates.
Convection currents and the mantle powerpoint
Heat from Earth's core causes convection currents in the mantle. Convection is the transfer of heat by the circulation of fluids such as liquids or gases. In Earth's mantle, hotter, less dense material rises while cooler, denser material sinks, driving convection currents that transfer heat from the core throughout the mantle. These mantle convection currents are influenced by the heating of the mantle from Earth's core and through the mantle itself.

Plate Tectonics
Wegener first proposed continental drift in the early 20th century, suggesting that continents were once joined together in a supercontinent called Pangaea. While evidence like matching coastlines and fossil distributions supported drift, Wegener could not explain the forces driving plate motions. In the 1960s, the new theory of plate tectonics emerged, proposing that Earth's outer layer is broken into rigid plates that move over the mantle. At plate boundaries, plates diverge, converge, or slide past each other, creating geological features like mid-ocean ridges and subduction zones. Paleomagnetic and seafloor spreading evidence confirmed plate tectonics, and mantle convection is now understood to be the primary driver of
seafloor spreading theory LP
This science lesson plan aims to teach 10th grade students about seafloor spreading through various classroom activities. Students will learn how seafloor spreading happens, how drill samples provided evidence of spreading, and the lines of evidence that support plate tectonics theory. The lesson involves engaging students with an animation and video on seafloor spreading, think-pair-share discussions, and an activity using a seafloor spreading model. Formative assessments include student diagrams illustrating seafloor spreading and additional activities on magnetic reversals are suggested for application and remediation.
PLATE TECTONICS
The document discusses plate tectonics and describes how the Earth's lithosphere is broken into plates that move over time. It explains that plate tectonics built upon Alfred Wegener's theory of continental drift, which proposed that the continents were once joined together in a supercontinent called Pangaea. There are nine major tectonic plates and three types of plate boundaries - divergent boundaries which create mid-ocean ridges and rift valleys, convergent boundaries which cause subduction and mountain building, and transform boundaries where plates slide past each other like the San Andreas Fault. Convection currents in the Earth's mantle provide the driving force for plate movements.
Plate tectonics
Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the lithosphere.
Dynamic earth ppt to go with notes
The theory of plate tectonics explains that Earth's outer layer is made up of plates that have moved throughout geological history. These plates float on top of the mantle and move at boundaries where they diverge, converge, or slide past one another. Convection currents in the upper mantle provide the driving force that causes plates to move over time.
Sea floor spreading
1) Tubeworms survive through a symbiotic relationship with bacteria that live inside them. The bacteria convert chemicals from deep sea vents into food for the worm.
2) Sonar uses sound waves to determine the distance to underwater objects by measuring the echo return time.
3) Sea-floor spreading was discovered by Harry Hess in the 1960s and explains how new ocean crust continually forms at mid-ocean ridges, pushing older rocks away.
Continental Drift Theory
This PPT takes a brief dig at the genesis of the Continental Drift Theory. It covers the causes and the evidences of the theory.
Plate Tectonic Theory
Plate tectonics developed from Alfred Wegener's theory of continental drift in the early 20th century. Wegener noticed coastlines of Africa and South America fit together and proposed all continents were once joined in a supercontinent called Pangaea. Later, scientists proposed mantle convection and sea floor spreading caused by convection currents in the mantle to explain plate movement. Today, plate tectonics theory describes the lithosphere broken into rigid plates that move across Earth's surface due to mantle convection and other forces, forming boundaries and landscape features.
Continental Drift Plate Tectonics
Continental drift theory proposed that the continents were once joined together in a supercontinent called Pangaea. Wegener provided evidence like matching fossil and rock formations across continents, but his theory was rejected due to lacking an explanation for how the continents moved. Later studies of the seafloor using sonar revealed mid-ocean ridges where new crust was formed, explaining continental drift through the process of seafloor spreading and plate tectonics. Earthquake data showed seismic activity occurs at plate boundaries, confirming the Earth's surface is composed of shifting tectonic plates.
Plate Tectonics
The document discusses plate tectonics and the structure and dynamics of the Earth's interior. It describes how the crust is broken into plates that move atop the mantle due to convection currents, and the three types of plate boundaries: divergent where plates move apart, convergent where they move together, and transform where they slide past each other. It provides examples of associated geological features like mid-ocean ridges, subduction zones, volcanoes, and earthquakes.
1636075841567_SCIENCE10_Q1_M4_Causes and Evidences of Plate Movement.pdf
Here are the answers to the questions:
Q1: The hypothesis of continental drift states that the continents were once joined together and have been slowly drifting apart over hundreds of millions of years.
Q2: Other scientists of Wegener's time rejected his hypothesis because he could not provide a mechanism to explain how and why the continents would move. They thought the continents were stationary.
Q3: The location of coal beds differs in the two continents. Coal beds in South America match those found in Africa, suggesting the two continents were once joined. This provides evidence supporting continental drift.
Continental Drift Theory
Alfred Wegener first proposed the theory of continental drift in the early 20th century. He noticed that the continents appeared to fit together and were once attached in a supercontinent called Pangaea. Wegener provided evidence from matching coastlines, fossil and rock formations, and paleoclimatic data to support his theory. However, he was unable to explain the mechanism of continental drift. Most geologists at the time rejected his theory due to the lack of a clear explanation for how and why the continents would move. It was not until the 1950s when the theory of plate tectonics was developed that Wegener's concept of continental drift became widely accepted.

Finally, students will glue the rearranged continents onto a map and answer questions about continental drift and the fit of continents in the supercontinent configuration.
Transform Plate Boundaries
This document discusses tectonic plates and transform plate boundaries. It notes that tectonic plates are large pieces of rock that make up Earth's crust, and there are two main types - oceanic and continental plates. At transform boundaries, the plates move horizontally past one another, driven by convection currents in the underlying mantle. When the plates rub together at these boundaries, it causes huge stress that results in earthquakes, faults, and tsunamis.
Plate tectonic ppt
Plate tectonics is the theory that Earth's outer layer is made of plates that move over Earth's rocky inner layer. In the early 1900s, Alfred Wegener proposed the idea of continental drift which later developed into the modern theory of plate tectonics. Pangaea, a supercontinent, broke apart starting 200 million years ago and the continents have continued moving apart on separate plates to their current positions. Plate boundaries include divergent boundaries where new crust forms, convergent boundaries where crust is consumed through subduction, and transform boundaries where plates slide past each other. The Mariana Plate forms the basement of the Mariana Islands and separates from the Philippine Sea Plate along a divergent boundary, while the Philippine

1. At destructive plate boundaries like subduction zones, denser oceanic plates descend under lighter continental plates, melting due to friction and forming volcanoes.
2. At collision boundaries, continental plates collide and buckle upwards, forming features like the Himalayas.
3. At constructive boundaries like the Mid-Atlantic Ridge, plates move apart and molten rock rises to fill the gap, creating new seabed and occasional low-strength volcanoes and earthquakes.
Dynamic Earth
The document summarizes the structure and composition of Earth's interior. It has four main layers from innermost to outermost - the solid inner core made of iron and nickel, the liquid outer core also made of iron and nickel, the solid mantle made of iron, silicon and magnesium minerals, and the rigid outer crust made of lighter rock. Temperature and pressure increase from the crust towards the core. The crust is thinnest under oceans and thickest under mountains.

Plate boundaries stresses faults ppt
This document discusses plate tectonics and the three types of plate boundaries: divergent boundaries, convergent boundaries, and transform boundaries. It describes how each boundary type results in different stresses on rocks and the formation of different geological features. Divergent boundaries result in tension stresses that cause normal faults and the formation of rift valleys or sea floor spreading. Convergent boundaries result in compression stresses that cause reverse faults and the uplifting of folded mountains or subduction zones and volcanoes. Transform boundaries result in shearing stresses that cause strike-slip faults like the San Andreas Fault in California.

Tectonic Plate Boundaries and Names
to display the names on the globe of the major tectonic plates.
Millions of humans live near the major tectonic plate boundaries. The potential dangers of living on or near a plate boundary include earthquakes, volcanoes, and tsunamis. However, these natural hazards do little to discourage people f.
SHS Earth and Life Quarter 1 Module 5.pdf
The document provides information about rock deformation from tectonic plate movements. It explains that when tectonic plates collide, spread apart, or slide past each other, they produce different geologic features and cause stress and strain in rocks. Compressional stress at convergent boundaries leads to folding and faulting, while tensional stress at divergent boundaries causes stretching and thinning. Shear stress at transform boundaries results in shearing and faulting as the plates slide past each other. The document contains images of potentially active faults in Cebu City from the Philippine Institute of Volcanology and Seismology.

Earth-and-Life-Science-Q1-Week-5.pdf
The document discusses how the movement of tectonic plates leads to the formation of folds and faults in the Earth's crust. It explains that compressional, tensional, and shear stresses from plate movements cause rocks to deform through either fracturing or bending. Fractures result in faults or joints, while bending forms folds such as anticlines, synclines, and monoclines. The movement of plates at convergent, divergent, and transform boundaries influences the type of stress and folding or fracturing that occurs. Folds and faults are important in forming new land masses.
Plate Bondraries
This document discusses plate boundaries and classifies them into three types: divergent boundaries, convergent boundaries, and transform fault boundaries. It provides examples of each type of boundary and explains their defining characteristics. Divergent boundaries form new crust through separation of plates, convergent boundaries involve the movement of two plates towards each other, and transform boundaries involve lateral movement of plates sliding past one another without creation or destruction of crust.
Mountains%2c earthquakes%2c volcanoes notes
The document discusses plate tectonics and how the movement of tectonic plates results in geologic processes like earthquakes, volcanic eruptions, and mountain building at plate boundaries. It describes the three types of plate boundaries where plates converge, diverge, or move past each other, and the associated stress, faulting, and landforms produced at each. The document also provides details on the formation and types of volcanoes, earthquakes, and related geologic hazards.

Globes and maps accurately represent the spherical Earth but maps are easier to use and carry. Globes show accurate shapes and distances while maps are two-dimensional so shapes and distances are distorted. Maps provide detailed information at local, regional or international levels.
Cardinal points establish direction. The principal points are north, south, east, and west. The sun can help establish direction as it moves across the sky. The North Star always indicates north. A compass needle always points north.
Relief maps show terrain and elevation. Thematic maps show subjects like climate or vegetation. Political maps show organization.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.
