Iceland's volcanoes are often strato-volcanoes, in contrast to the shield volcanoes of Hawaii - the C172p tutorial airport (PHTO) is located in a town at the foot of to 2 huge shield volcanoes. Strato-volcanoes have steeper sloping sides, as the lava that comes up often is more viscous for periods of time - it flows less easily, like honey compared to water. This lava becomes hard before spreading far. Lava, before it reaches the surface, is called magma. Strato-volcanoes have periods where the magma coming up is viscous, and eruptions can be explosive - as gasses dissolved in the magma remain trapped. These eruptions can cause craters. Shield volcanoes only tend to have magma that flows easily, so they have very shallow slopes (as low as 5 degrees) as the lava spreads far. Iceland does have shield volcanoes, but they are smaller. | Iceland's volcanoes are often strato-volcanoes, in contrast to the shield volcanoes of Hawaii - the C172p tutorial airport (PHTO) is located in a town at the foot of to 2 huge shield volcanoes.

Mount Herdubreid (a table mountain) is a volcano in Vatnajökull National Park, Iceland. The volcanic desert it sits on is a lava field created from easily flowing eruptions of nearby shield volcanoes: | Mount Herdubreid (a table mountain) is a volcano in Vatnajökull National Park, Iceland.

To re-create the stark subpolar setting, remember to turn on overlays which add high resolution 3d detail, and set [http://wiki.flightgear.org/Anti-aliasing#Transparency_anti-aliasing Transparency Anti-Aliasing] to MSAA in the GPU control panel (or super-sampling on powerful GPUs). As Iceland has few trees, people with older GPUs may find they have spare performance and can use overlays in Iceland. | To re-create the stark subpolar setting, remember to turn on overlays which add high resolution 3d detail, and set [http://wiki.flightgear.org/Anti-aliasing#Transparency_anti-aliasing Transparency Anti-Aliasing] to MSAA in the GPU control panel (or super-sampling on powerful GPUs).

A place needs 4 dimensions to describe it, 3 in space and 1 in time. Any default setting can only be a moment in time, and in FlightGear the ever-changing cycles of nature are simulated from the Environment > Environment Settings menu. In FlightGear's environment sliders, Iceland is often suited being towards the autumn season with wet ground and moss. The more northern seas away from the south coast can ice up, so remember the ice cover control. | A place needs 4 dimensions to describe it, 3 in space and 1 in time.
