The volcanic island is just 60 miles from the North African coast. The Sun ( 2011 ) The remote volcanic islands of the Galapagos are a spectacular showcase for some of nature's oddest animals.
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging , and because most of Earth's plate boundaries are underwater, most volcanoes ...
