Folding, Faulting & Earthquakes is one of 9 topics in the Grade 10 Geography CAPS syllabus, covered across 3 lessons on Study Vault. Below are real practice questions from this topic with full worked answers.
Sample practice questions
Easy
1. An upward-arching fold in rock layers is called a(n):
Anticline
Syncline
Normal fault
Horst
Answer: Anticline — An anticline is an upward-arching fold, while a syncline is a downward-sagging fold; both form when rock layers bend under compressional forces.
Easy
2. Folding tends to occur when rock is subjected to compressional forces while being relatively:
Ductile (able to bend)
Brittle (unable to bend and prone to fracturing)
Completely molten
Frozen solid at extremely low temperature
Answer: Ductile (able to bend) — Folding occurs when rock is relatively ductile, able to bend and buckle under compressional force rather than fracturing, unlike brittle rock, which faults.
Medium
3. What term describes a fault where tensional forces pull rock apart, causing one block to slip downward relative to the other?
Answer: A normal fault — A normal fault occurs where tensional forces pull rock apart, causing one block to slip downward relative to the other along a steeply angled fault plane.
