Volcanoes

Volcanoes

Volcanoes form by two tectonic plates clashing together and bending upwards since the force is so big and sometimes the layer below flows upwards and the layers below are magma and lava.

The temperature there could be as low as 90C . It is very hot inside an active volcano. The temperature there could be as high as 1300°C (2372°F).

Volcanoes can cause a earthquake,tsunami,etc.

Theres volcanoes that can erupt blue lava and its even hotter than normal lava.

Acient civilizations after a volcano erputed they collected the dried up lava that is called igneous rock and they used it to craft objects and also collected obsidian to make sharp spears or weapons.Obsidian is often found near active volcanic areas
