Q. Due to less amount of silica, the basic lava is:
✅ Correct Answer: (C)
less viscous than acid lava
Explanation:
Basic lava contains less silica and hence is less viscous (flows more easily).
- Acid lava (high silica content) is more viscous and sticky.
- Viscosity affects how lava flows during volcanic eruptions.
So, basic lava is less viscous than acid lava — option (C).
