Individual lava flows are normally only a few feet thick, but over a long period of time, repeated flows may build up a volcano. Such volcanoes are termed as:
General KnowledgeGeography
- AShield volcano.
- BComposite volcano.
- CStrato-volcano.
- DCinder-cone volcano
Explanation
Shield volcanoes (e.g., Mauna Loa, Hawaii) are built by repeated outpourings of thin, fluid basaltic lava — each flow only a few feet thick — accumulating over a long time into a broad, gently sloping dome. Composite (strato) volcanoes instead alternate lava with ash from explosive eruptions; note options B and C are near-synonyms, confirming the intended answer is the distinct shield volcano.
