Question

10.describe the local and global effects a volcanic eruption can have on the environment.

Explanation:

Local effects include lava flows, ashfall, and pyroclastic flows destroying vegetation, habitats, and infrastructure. Global effects involve volcanic gases (e.g., SO₂) causing acid rain, aerosols reflecting solar radiation leading to temporary global cooling, and impacts on atmospheric chemistry and climate patterns.

Answer:

Local effects: Lava flows, ashfall, pyroclastic flows destroy vegetation, habitats, infrastructure. Global effects: Volcanic gases (e.g., SO₂) cause acid rain; aerosols reflect sunlight, leading to temporary global cooling; impacts on atmospheric chemistry and climate.
