Name: _______________________________Ch. 7 Section 4 Deforming the Earth’s Crust
Directions: Begin reading Ch. 7 Section 4 on page 181. As you read, answer the questions below.
1. In your own words define stress. _______________________________________________________________________________
____________________________________________________________________________________________________________
2. What happens to a rock when it gets deformed? ___________________________________________________________________
3. Describe the type of stress called compression. ____________________________________________________________________
____________________________________________________________________________________________________________
4. Describe the type of stress called tension.________________________________________________________________________
____________________________________________________________________________________________________________
5. What happens to a rock when it bends due to stress?________________________________________________________________
6. Name and draw a sketch of the 3 types of folds in the table below.

7. Rocks bend and fold due to stress. What is it called when rocks break or snap due to stress? ________________________________
8. Name and draw a sketch of the 3 types of faults in the table below.

9. We know mountains form from the movement of Earth’s plates. When plates collide small features like folds and faults are formed.
Over time these small features can become great mountains. In the table below, name the 3 types of mountains, describe how each
mountain forms, and draw a sketch of each mountain.

The movement of Earth’s Tectonic Plates shapes the surface in many ways. One of the most amazing features shaped by the
movement of the plates is the Earth’s mighty mountain ranges. Mountains can be found on every continent and even at the bottom of
the sea floor. In this activity we want to investigate the different ways that mountains form due to plate movement. You will be
assigned two different mountain ranges to research. We want to know where they are located, what type of plate boundary are they
near if any, and how they formed. Fill in the table below with your information. Use the table as a guide for your research.
Name of Mountain Ranges
1.
2.
Where are the mountains located?
(Country/State/Region)
Are the mountains near/on a plate
boundary? If so, what plates make
up the boundary?
If the mountains are near on/a plate
boundary, what type of plate
boundary is it?
What type of mountain ranges is it?
What is the age of the mountains?
On the map below, draw the symbol for mountains where your two mountain ranges are located. Also on the map, draw the nearest
plate boundaries that you think played a role in making your two mountain ranges (see page 170 for plate locations).
