It is caused by a pressure build up deep in the earths core, which, if not released slowly, can explode violently. 

The volcano has 2 main effects, first the ash can block out the sun, cause people to be unable to breathe.  The second effect is the lava or magma, which can destroy buildings and forests.

One of the most famous recent volcanic eruptions was  Eyjafjallajökull in Iceland. Although no one was killed, it did stop all air travel for months globally.]]> 2022-05-06 11:50:16 UTC https://padlet.com/kais22/7b/wish/2172758271 Sinkholes https://padlet.com/kais22/7b/wish/2172788496 A sinkhole is a hole in the ground caused by some form of collapse of the surface layer.   

Sinkhole is caused where the rock below the land surface is limestone, carbonate rock, salt beds, or rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, the surface above collapses and sinkholes are formed. 

The sinkhole can lead to a lot of damage to human life and property, especially when it happens in crowded areas. 

The largest sinkholes known is one in the limestone mountains of Nongle in Guanxi Zhuang region in southern China. 

It is both manmade and natural.
