Forces in Earth’s Crust
Stress A force that acts on an area of rock to change its shape or volume.
There are 3 types of stress Tension stretches rocks Compression pushes rock together Shearing pushes the rock in two opposite directions
Questions What type of landforms results from tension? What type of landform results from compression?
Faults When enough stress builds up in rock, the rock breaks, creating a fault. Most faults occur along plate boundaries
There are 3 kinds of faults Normal Faults - Tension in crust pulls rock apart. Reverse Faults - Compression pushes rock together Strike-Slip Faults – Shearing causes rocks to slip past each other
Mrs. Brown’s Fault Movie
Hanging Wall – The block of rock that is above the fault plane Footwall – The block of rock that is below the fault plane.
In a normal fault, the hanging wall slips down relative to the footwall
In a reverse fault, the hanging wall moves up relative to the footwall
San Andreas fault is a strike-slip fault with little up or down motion
The forces of plate movement can change a flat plain into anticlines, synclines, folded mountains, fault-block mountains, and plateau.
Fault Block Mountain When two normal faults cut through a block of rock, a fault block mountain forms.
Q: Where in California are there fault-block mountains? A: The Sierra Nevada and Mojave Desert regions.
Plateau A large area of flat land elevated high above sea level without much folding or faulting.
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?
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.
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.
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 4 Section 1 Types of Stress Forces Types of Faults.
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 (pages 162–168). Key Questions What happens to rocks when they are placed under the large forces created by plate movements?
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.
NORMAL Fault formed by the stress of TENSION where plates were pulled apart. The Hanging Wall fell and the Footwall was raised.

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.
Bellringer Describe how Plate Tectonic forces and earthquakes might be related.
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.
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.
Stress – force that pushes or pulls rock Tension Compression Shearing Fault – Break in Earth’s crust where plate movement occurs Normal Reverse Strike-Slip.

Changes in the Earth’s Crust. What is stress? You get stressed when you have too much work or have a test to study for You can get stress in certain parts.
Earthquakes - Forces in Earth’s Crust Types of Stress The stress force called tension pulls on the crust, stretching rock so that it becomes thinner in.
Earthquakes. Types of Stress Stress: a force that acts on rock to change its shape or volume. – Because stress is a force, it adds energy to the rock.
