Plate Tectonics What evidence do scientists have to support the fact that the Earth’s crust is continuously moving?
Plate Tectonics The theory that describes how tectonic plates move and shape Earth’s surface Tectonic plates are huge pieces of crust that fit together at their edges to cover Earth’s surface.
About 12 plates exist on Earth
Earth’s Interior Crust – Rigid outer shell of Earth MantleOceanic and Continental Crust Mantle Upper mantle is partially molten Lower mantle is rigid (solid)
Earth’s Interior Core Outer core is molten iron, source of Earth’s magnetic field Inner core is solid, Iron and Nickel
Plate Boundaries Divergent Boundary Convergent BoundaryTransform Boundary
Divergent Boundary Two tectonic plates move apart from each otherRift valleys – long narrow depressions Rift valley in East Africa
Convergent Boundary Two tectonic plates move towards each other (come together) Oceanic Plates are more dense Continental Plates are less dense
Subduction Process when one tectonic plate slips beneath another plate
Oceanic – Oceanic Subduction Occurs Deep Sea Trenches (Marianas Trench)
Oceanic – Continental Subduction Occurs Trench and Volcanic Arch (Peru – Chile Trench)
Continental – ContinentalMountain Building Himalayas Aleutian Islands
Transform Boundary Region where two plates slide past each otherEarthquakes occur at transform boundaries San Andreas Fault in San Francisco

What is it? And what makes it work?. Our Earth Not a solid ball of rock Composed of distinct layers Three main layers based on composition:
Essential Questions How does the movement of Earth’s tectonic plates result in many geologic features? What are the three types of plate boundaries and.
Plate Tectonics – Section Describe how Earth’s tectonic plates result in many geologic features. Compare and contrast the three types of plate.
Earths Structure Goal: Be able to identify the structure of the earth’s interior.
Seafloor Spreading Theory Explains how ocean crust is formed at ocean ridges and destroyed at deep- sea trenches Supports Wagener’s continental drift.
Inner core – hot, solid iron and nickel Outer core – hot, molten iron and nickel Mantle – hot rock Crust – solid outer layer of the Earth 1.
Plate Boundaries. Earth’s outer layer is divided into many strong, moving lithospheric plates lithospheric Tectonic Plates Plate Tectonics.
The Earth’s Interior & Plate Tectonics Physical Science Chapter 17 Section 1.
Plate Boundaries JOURNAL PAGE 65. The edges of the plates meet at lines called plate boundaries. When rocks slip past each other along these boundaries.
Plate Boundaries Earth’s crust plus the upper mantle forms the lithosphere. Earth’s lithosphere is broken in a number of different pieces. How these pieces.
Types of Plate Boundaries After completing this section, students will identify that the Earth is made of geologic plates (Standard PI-041) and investigate.
TERRA FIRMA Plate interactions. EARTH’S INTERIOR crust under the oceans - basalt (more dense) crust under the continents - granite (less dense) mantle.
Plate Tectonics. What is Plate Tectonics The Earth’s crust and upper mantle are broken into sections called plates These plates move around on top of.
The Theory of Plate Tectonics 3.3 notes How plates move The theory of plate tectonics states that pieces of Earth’s lithosphere are in slow, constant.
Plate Tectonics. The crust is broken into plates that float on the mantle. The crust is broken into plates that float on the mantle. Sometimes the plates.
Bell Work: September 3 Define The Plate Tectonic Theory What are some ways that plate tectonics change the surface of the earth?
17.3 Plate Boundaries Objectives Describe how Earth’s tectonic plates result in many geologic features Compare and contrast the 3 types of plate boundaries.
The Earth’s Interior & Plate Tectonics. The Earth’s Interior The Earth’s Interior can be broken up into 4 major zones Crust Mantle Outer core Inner core.
Guided Notes on the Theory of Plate Tectonics Chapter 17, Section 3.
Plate Tectonics. The Theory of Plate Tectonics is a theory that describes the formation, movements, and interactions of Earth’s lithospheric plates that.

Plate Tectonics Plate Boundaries and Interactions.
J. Tuzo Wilson was a Canadian scientist. He observed that there were cracks in the continental crust similar to those on the ocean floor. Wilson.
Plate Tectonic Theory Notes. How Plates Move Earth’s crust is broken into many jagged pieces. The surface is like the shell of a hard-boiled egg that.

Plate Tectonics. What is Plate Tectonics? Wikipedia defines Plate Tectonics as the large-scale movement of the Earth’s Lithosphere. Basically, the Earth’s.
Our Amazing Planet. Engage Assignment Make a 3 slide power point on each of the three types of plate boundaries – Convergent boundaries – Divergent boundaries.
Our Amazing Planet. Planet Earth Earth’s Layers Crust Earth’s thin outermost layer. – Continental Crust (land) - thick low density rock (granite). –
Plate Tectonics. Continental Drift _________ proposed the theory that the crustal plates are moving over the mantle. This was supported by fossil and.
Internal Structure of the Earth Plate Tectonics Sea Floor Spreading.
1.1 Earth has several Layers. Denser material sinks Less dense material rises to the top.
Composition of the Earth. Earth Layers The earth isn’t a solid sphere It is made of 4 major layers - Crust - Mantle - Outer core - Inner core.
Plate Tectonics Scientist, Tuzo Wilson, combined the knowledge of sea-floor spreading, earths plates, and continental drift into a single theory- The Theory.
Scientists identify the boundaries between two plates by the plate movement. There are three types of plate boundaries: 1. Divergent 2. Convergent.
