Earth’s Crust in Motion Section 5-1
Earthquake Shaking that results from rock movement below Earth’s surface
Force that acts on Earth’s crust to change its shape or volume
3 kinds of stress 1.Shearing One rock, Two directions.
3 kinds of stress 2.Tension Stretches rock
3 kinds of stress 3.Compression Squeezes rock
Fault Break in rock Caused by stress Slabs of crust slip past each other Usually occur at plate boundaries
3 kinds of FAULTS 1.Shearing → Strike-slip faults Slip past sideways, no vertical motion “Transform boundary” at plate boundaries
3 kinds of FAULTS 2.Tension → Normal faults At an angle Above fault = Hanging Wall (slips down↓↓) Below Fault = Footwall
3 kinds of FAULTS 3.Compression → Reverse faults At an angle Hanging Wall (slips up↑↑↑)

Forces in Earth’s Crust Part 1. Stress: a force that acts on rock to change its shape or volume *The movement of Earth’s plates creates an enormous force.
Section 1: Forces in Earth’s Crust How does stress in the crust change Earth’s surface? Where are faults usually found, and why do they form? What land.
Ch6 Sec1 Forces in Earth’s Crust. Key Concepts How does stress in the crust change Earth’s surface? Where are faults usually found, and why do they form?
Section 1. Stress is a force that acts on rock to change its shape or volume. A rock’s volume is the amount of space that the rock takes up. Stress.
Chapter 6 Earthquakes. stress -a force that acts on a rock to change its shape or volume - “pushing” and “pulling” of rocks Rock deforms in 3 ways: -compression.
Inside Earth Chapter 2 Earthquakes 2.1 Forces in Earth’s Crust.
Earth’s Crust in Motion Chapter 5.1. What is an earthquake? What causes earthquakes? Earthquake: The shaking and trembling that comes from the movement.
Earthquakes. An Earthquake is… the shaking and trembling that results from the movement of rock beneath Earth's surface The movement of Earth's plates.
Earth's Crust in Motion. Earthquakes So…. What is an Earthquake? And… What are some things that can cause them?
Stress – force that pushes or pulls rock Tension Compression Shearing Fault – Break in Earth’s crust where plate movement occurs Normal Reverse Strike-Slip.
Crust in Motion Chapter 5, Section 1 Monday, January 25, 2010 Pages
3 Types of Stress 1. Tension: stress that pulls rock apart Rock gets thinner in the middle 2. Compression: stress that pushes rock together 3. Shearing:
Forces in Earth’s Crust. Stress A force that acts on an area of rock to change its shape or volume.
Section 3 Theory of plate tectonics. Plate tectonics The theory that the Earth’s lithosphere is divided into tectonic plates that move around on top.
Forces in Earth’s Crust Created by the Marvelous Mr. Christine 8 th Grade Science.
Chapter 4 Section 1 Types of Stress Forces Types of Faults.
Chapter 11, Section 1 Forces Inside the Earth. Elastic Deformation The ability of an object to bend and stretch without breaking.
Deforming Earth’s Crust. Stress = Force Arrows Stress: Amount of force per unit area The reaction when rocks change shape due to stress is called Deformation.
Lesson 1 – Forces in Earth’s Crust. The movement of Earth’s plates creates an enormous force that squeezes or pulls rock in the crust as if it were.
You’re stressing me OUT! Stress-a force that acts on rock to change its shape or volume.
Earth’s Crust in Motion. Stress in the Earth’s Crust An earthquake is the shaking and trembling that results from movement of rock beneath the Earth’s.
Chapter 6 – Earthquakes Section 1: Forces in Earth’s Crust.
Deforming the Earth’s Crust. Deformation This is the process where the shape of rocks change. Caused by: Compression- Objects are squeezed; when 2 plates.
Earthquakes Faults & Stress Write everything in BLUE!
Unit 1.4 Earthquakes. Where do earthquakes Occur? Earthquakes can occur near the Earth’s surface or far below the surface. Most earthquakes occur at plate.
Earth’s Crust in Motion EQ: How do stress forces affect rock?
Crust Deformation: Forces, Faults and Folds. Deformation The bending, tilting, and breaking of the earth’s crust major cause of deformation = plate tectonics.
Earthquakes Earth’s Crust In Motion Guide For Reading How does stress forces affect rock? Why do faults form and where do they occur? How does movement.
Earth’s Crust in Motion. Stress The surface of the earth is divided into 13 major tectonic plates. These plates interact with each other constantly.
Forces in Earth’s Crust (pages 162–168). Key Questions What happens to rocks when they are placed under the large forces created by plate movements?
Forces in Earth’s Crust Chapter 6 Section 1. Earthquakes Elasticity is the ability for an object to return to or keep its original shape Which is more.
Key Terms: displacement, strike slip fault, dip slip fault, right lateral fault, left lateral fault, normal fault, reverse fault, thrust fault Use the.
stress -a force that acts on rock to change its shape or volume. 3 Types of Stress tension -pulls on crust, stretching rock so it becomes thinner.
Earthquakes. Earthquakes are natural vibrations of the ground, caused by: Fractures in earths crust Volcanic eruptions.
Earthquakes: Forces Inside of Earth. Earthquake Causes Fault Formation –Rocks can bend and stretch up to a point – just like a rubber band or popsicle.
Earthquakes Earthquakes: the shaking and trembling that results from the movement of rock beneath Earth’s surface See simulation below: Terashake.
NOTES FAULTS and FOLDS. What is a fault? A fault is a fracture or series of fractures in Earth’s crust that occurs when stress is applied too quickly.
Section 1: Earth’s Crust in Motion How Do Stress Forces Affect Rock? The movement of earth’s plates creates powerful forces that squeeze or pull the.
EARTHQUAKES. TYPES OF STRESS Tension- pulls on the crust stretching rock so that it becomes thinner in the middle. Compression- Squeezes rock together.
Earthquakes Chapter 2 book F page 44. Vocabulary for section 1 page 44 book F Stress Tension Compression Shearing Normal fault Reverse fault Strike-slip.

Chapter 15.4 Deforming the Earth’s Crust stress a force that acts on rock deforming it’s shape or volume.
Do Now for Wednesday, February 20 th ! Use your knowledge of the Law of Superposition to arrange the layers of Earth from oldest to youngest.
Plate Tectonics Chapter 1 Section 5. Plates What is a plate? A plate is a piece of the lithosphere Plates fit closely together along cracks.
Forces Inside Earth (43) Once the elastic limit is passed, the rocks may break When rocks break, they move along surfaces called faults To relieve this.
