A windfarm on Lanzarote, Canary Islands, and a ploughed field in the foreground. The field is strewn with volcanic rocks and is therefore very difficult to cultivate. The pumice rocks are often collected to build walls and cultivation shelters. Pumice is an igneous rock with holes or vesicles formed by gas trapped in the liquid magma when it is ejected in a volcanic eruption. | |
