Types of Stress

Stress & plate boundaries

Types of Stress

What type of landform results from tension?

valley

What type of landform results from compression?

mountain

Silly PuttyStress

Page 5: Chapter 6 – Earthquakes Section 1: Forces in Earth’s Crust.

Silly PuttyWhich part of this activity models

the type of stress that would produce anticlines and synclines?

When we pushed the ends together – compression

Folding Earth’s Crust

Folding Earth’s Crust

Who can point out an anticline?

Where is a syncline in this picture?

Page 8: Chapter 6 – Earthquakes Section 1: Forces in Earth’s Crust.

How can I tell the difference among the three types of faults?

Normal fault

Tension

Hanging wall moves down

Reverse fault

Compression

Hanging wall moves up

Strike-Slip fault

Shearing

Movement is side-to-side w/ very little up/down

Do hand models here.

Types of Faults

What type of fault is this?

Normal faultWhat stress causes

this?tensionWhich wall moves –

the hanging wall or the footwall?

The hanging wallIn what direction?down.

Types of Faults

What type of fault is this?

reverse faultWhat stress causes

this?compressionWhich wall moves –

the hanging wall or the footwall?

The hanging wallIn what direction?Up and over the

footwall

Types of Faults

What type of fault is this?

Strike-slip faultWhat stress causes

this?shearingHow is this fault

different from the other two?

Rocks slip past each other with very little up/down movement.
