Lesson 6

Formation of Folds and Faults

Activity 1 :

Tracing the Origin

Directions: Trace the reason how the folds and faults are created using the

illustration below.

A.

c.

Continental-Oceanic Convergent Plate Boundary Transform Plate Boundary Divergent Plate Boundary

d.

Questions:

  1. What plate boundary would result to: a. Mountain Ranges: Continental-Continental Convergent Plate Boundary b. Seafloor Spreading: Divergent Plate Boundary c. Continental Volcanic Arcs: Continental-Oceanic Convergent Plate Boundary d. Fault Lines: Transform Plate Boundary
  2. Which of the plate boundary do you think would result to folding? Continental-Continental Convergent Plate Boundary
  3. How the plate boundary in item no. 2 does develops a geologic fold? When two continental plates converge, instead of subduction, the two similar tectonic plates will buckle up to create large mountain ranges like a massive car pile-up. This is called continental-to-continental convergence, and geologically creates intense folding and faulting rather than volcanic activity. Examples of mountain ranges created by this process are the Himalayan mountains as India is colliding with Asia, the Alps in Europe, and the Appalacian mountains in the United States as the North American plate collided with the African plate when Pangea was forming. The Kashmir India earthquake of 2005 that killed over 80, people occurred because of this process. And most recently, Continental-Continental Convergent Plate Boundary
