Consider the following statements regarding Volcanic Cones :
- 1During volcanic eruptions, acid lava cones are formed by highly viscous lavas.
- 2Viscous lavas have high mobility and can travel for long distances.
- 3Acid lavas result in the formation of high cones with steep slopes.
- 4Composite cones are the highest volcanic cones.
Which of the statements given above are correct ?
General KnowledgeGeography
- A1 and 2 only
- B2, 3 and 4 only
- C1, 3 and 4 only
- D1, 2, 3 and 4
Explanation
Acid (silica-rich) lavas are highly viscous and build volcanic cones (statement 1 true). Viscous lavas have low mobility and pile up near the vent rather than travelling far, so statement 2 is false. Acid lavas therefore form high cones with steep slopes (statement 3 true). Composite (strato) cones are the tallest volcanic cones (statement 4 true). Hence statements 1, 3, and 4 are correct.
