Question

Which of the following is NOT a constructive effect of volcanoes?

Options

• Landform formation

• Tsunami

• Geothermal energy

• Tourism

Answer 1

Tsunami

Explanation:
A tsunami is not a constructive effect of volcanoes; it is a destructive effect. Tsunamis are large, powerful sea waves usually triggered by underwater volcanic eruptions or earthquakes, causing widespread destruction along coastlines. In contrast, the other options, landform formation (like new islands or fertile plains), geothermal energy (used for power and heating), and tourism (attracting visitors to volcanic landscapes), are all constructive effects that benefit humans and the environment.
