PPT G2 - Earth Materials and Processes

advertisement
Let’s Review:
1. What is continental and plate tectonics theory all about?
2. How are these theories related to the formation of plate
boundaries?
3. What are the different types of plate boundaries?
4. What are the geologic features formed from each
boundary?
Learning Objectives:
I can…
• Identify the different tectonic forces
• Explain the effect of the movement plates that leads to the formation
of folds and faults
• Relate the current phenomena (e.g. Coral Garden in Loon Bohol,
etc.) to how movement of plates leads to the formation of folds and
faults
Let’s see these geologic features…

Form 6 groups with 6-7 members
each
Perform one of the two activities
based from the materials
assigned to you
Activity 1: Fold the Clay (Gr. 1-3)
Activity 2: The Faulty Set-up (Gr.
4-6)
Follow the procedures from the
given worksheets
Answer the guide questions after
performing the activity
Prepare for a short
presentation/simulation
afterwards
Have fun!! 

Sample Worksheets
Tectonic Forces and Processes
•
Deformation refers to
the change in the
original shape and size
of a rock.
•
When rocks are
subjected to stresses
(tectonic features), they
begin to deform.
Deformation
Folding
Faulting
Tectonic Forces and Processes
Folding
• This occurs when
rocks are pushed
towards each
other from the
opposite sides.
Tectonic Forces and Processes
Anticline- upward arch
Syncline – downward arch
Limbs- sides of the folds
Dome – a circular or elliptical
anticline in which limbs dip
away in all directions.

Tectonic Forces and Processes
Faulting
•
It is the
fracturing and
displacement of
brittle rocks
strata along a
fault plane.
Normal Fault
Reverse Fault
Strike-Slip Fault

Guide Questions:
1. What are the significant effects of the movement of plates
to the formation of these geologic activity/ features
presented from the article?
2. How do these effects affect the community and society?
Assignment
Write an essay summarizing the “big ideas” you have
learned from the articles on how movement of plates
leads to the formation of folds and faults in a 1 whole
sheet of paper.
