Volcanic Activity and Its Impacts

In some cultures, how are volcanoes perceived in a spiritual context?

• As sources of pure water.

• As places where deities reside.

• As ancient burial grounds.

• As navigational landmarks.

What term describes the process when a dormant volcano becomes active again?

• Erosion.

• Subduction.

• Awakening.

• Crystallization.

The high fertility of volcanic soil is primarily due to its abundance of what?

• Organic matter from decaying vegetation.

• Nitrogen-fixing bacteria.

• Weathered volcanic ash and minerals.

• High concentrations of salt.

What is a significant long-term benefit of volcanic activity for surrounding ecosystems?

• Increased seismic stability.

• Formation of new mineral deposits.

• Creation of highly fertile soil.

• Enhanced atmospheric cooling.

Beyond agricultural benefits, what valuable natural resource is often associated with volcanic regions?

• Petroleum

• Sulfur

• Diamonds

• Uranium

What geological phenomenon often precedes a volcanic eruption, indicating increased activity within the volcano?

• Prolonged droughts.

• Significant atmospheric pressure drops.

• Increased seismic tremors.

• Sudden changes in ocean currents.

What immediate societal response is typically triggered when a volcano poses a high threat of eruption?

• Construction of new settlements.

• Mass evacuation of nearby populations.

• Implementation of cloud seeding.

• Expansion of agricultural land.

What is a common immediate consequence for human populations living in the vicinity of a highly active volcano?

• Increased tourism opportunities.

• Forced displacement and seeking refuge.

• Development of new agricultural techniques.

• Improved air quality.

What approach is suggested for communities living near active volcanoes to coexist peacefully with nature?

• Exploiting all available resources without restraint.

• Ignoring the potential dangers and continuing as usual.

• Respecting the environment and its natural processes.

• Relocating all populations to distant, safer areas.

Despite the immediate destructive potential of volcanic eruptions, what long-term environmental benefit can they provide?

• Reduction in global sea levels.

• Creation of new freshwater sources.

• Enrichment of soil leading to increased fertility.

• Formation of new atmospheric layers.
