Describe the global distribution of earthquakes and volcanic eruptions and their relationship to plate margins.

Earthquakes and volcanic eruptions are not randomly distributed across the globe; they primarily occur along plate margins where tectonic plates interact. At constructive margins, plates move apart, allowing magma to rise and create new crust, often resulting in volcanic activity. Destructive margins involve one plate being forced under another, leading to intense seismic activity and the formation of volcanoes. Conservative margins, where plates slide past each other, can also generate earthquakes. Understanding this distribution helps in predicting where these natural hazards are likely to occur and in assessing the risks they pose to nearby populations.
