There are three main types of plate boundaries: convergent boundaries where plates collide and come together, divergent boundaries where plates move apart, and transform boundaries where plates slide past one another. Convergent boundaries result in features like volcanic mountains and deep trenches, while divergent boundaries form rift valleys and ocean ridges due to seafloor spreading. Folds form from compressional forces bending ductile rocks, and faults occur when tensional forces cause rocks to crack along fissures.

Plate Boundaries- are
the “edges” where two
plates meet.

CONVERGENT
= Converge or Collide
( To come together;
Meet at one point)

each other)

= Two S: SIDE to SIDE

13. HOW FOLDS AND
FAULTS FORMED?

14. FOLDS
•ARE BENDS IN THE ROCKS THAT ARE DUE TO
COMPRESSIONAL FORCES
•FOLDING OCCURS WHEN COMPRESSIONAL FORCE IS
APPLIED TO ROCKS THAT ARE DUCTILE OR FLEXIBLE.

16. FAULTS
•FAULTS ARE DUE TO TENSIONAL FORCES ALONG
WHICH DISPLACEMENTS OF ROCKS TAKE PLACE.
•FAULTS OCCUR WHEN FORCES OPERATING IN
OPPOSITE DIRECTIONS LEADS TO TENSION AND AS A
RESULT ROCKS DEVELOP CRACKS ON THE FISSURE
