whose
Whose work first explained why volcanoes can erupt explosively instead of quietly?
Modern volcanology explains explosive eruptions through gas-rich magma, and pioneering studies by geologists such as George Walker helped classify eruption styles. Their work linked magma properties to eruption violence.

how
How do sinkholes suddenly open up?
They form when underground cavities grow too large for the surface rock to support. The ground can collapse abruptly, especially in karst areas or where groundwater levels change quickly.

why
Why are some earthquakes harder to predict than volcanic eruptions?
Earthquakes often rupture on faults that are hidden deep underground, while volcanoes usually show more visible warning signs like gas, swelling, and small quakes. That makes the exact timing of earthquakes much harder to narrow down.
