Volcano A 2007 eruptive column at Mount Etna producing volcanic ash, pumice and lava bombs Santa Ana Volcano, El Salvador, a close up aerial view of the nested summit calderas and craters, along with the crater lake as seen from a United States Air Force C-130 Hercules flying above El Salvador. Erupting volcanoes can pose many hazards, not only in the immediate vicinity of the eruption. One such hazard is that volcanic ash can be a threat to aircraft, in particular those with jet engines where ash particles can be melted by the high operating temperature; the melted particles then adhere to the turbine blades and alter their shape, disrupting the operation of the turbine. Large eruptions can affect temperature as ash and droplets of sulfuric acid obscure the sun and cool the Earth's lower atmosphere (or troposphere); however, they also absorb heat radiated up from the Earth, thereby warming the upper atmosphere (or stratosphere).

As the term situation embraces the total physical, biological, cultural and aesthetic components of an area, it is generally regarded as too broad and around a term for landscape.

Watkins Glen State Park Watkins Glen State Park is the most famous of the Finger Lakes State Parks located on the edge of the village of Watkins Glen, New York, south of Seneca Lake in Schuyler County. The main feature of the park is the hiking trail that climbs up through the gorge, passing over and under waterfalls. The park has a lower part that is next to the village and an upper part that is open woodland. Watkins Glen State Park is in a 400-foot-deep narrow gorge cut through rock by a stream that was left hanging when glaciers of the Ice age deepened the Seneca valley, increasing the tributary stream gradient to create rapids and waterfalls wherever there were layers of hard rock. The gorge path winds over and under waterfalls and through the spray of Cavern Cascade.
