Caves, arches, stacks and stumps are the landscape features of which one of the following?
- A.River
- B.Wave
- C.Limestone
- D.Wind
Correct answer
Explanation
The correct answer is B, Wave. Caves, arches, stacks and stumps are erosional landforms carved by sea waves on rocky coasts.
Waves attack a headland from both sides and wear away the weaker rock along cracks. First a sea cave forms. When caves on two sides of a headland meet, the opening becomes a sea arch. When the roof of the arch collapses, the seaward part is left standing alone as a pillar called a stack. As the stack is worn down further, a short stump remains, often visible only at low tide. Other wave-made features include sea cliffs, wave-cut platforms and, where waves deposit sand, beaches, spits and bars.
A is wrong because rivers make V-shaped valleys, gorges, meanders, ox-bow lakes and deltas. C is wrong because limestone areas show karst features such as sinkholes, stalactites and stalagmites. D is wrong because wind makes mushroom rocks, sand dunes and loess.
Exam tip: the coastal sequence is cave, arch, stack, stump, each formed when the one before it is worn down.
