One could say, for example, that large lava flows are erupted from Kilauea volcano in Hawaii, the world volcano… View Article

Erupted Material

Another way of classifying volcanoes is by the composition of material erupted (lava), since this affects the shape of the volcano. Lava can be broadly classified into 4 different compositions (Cas & Wright, 1987): * If the erupted magma contains a high percentage (>63%) of silica, the lava is called felsic. * Felsic lavas (dacites… View Article

Endogenetic Process

The Endogenetic processes are the processes that shape the land by forces coming from within the earth (Endogenetic forces). There are 3 main Endogenetic processes: folding, faulting and volcanism. They take place mainly along the plate boundaries, which are the zones that lay on the edges of plates. These zones are weak. Endogenetic processes cause… View Article

Underwater Volcanoes

Submarine volcanoes or underwater volcanoes, come in all shapes and sizes and, are found across the world from Hawaii and California to Iceland, Japan, New Zealand and Antarctica. Worldwide, there are an estimated 5,000 active submerged volcanoes, with the highest volcanoes in shallow water rising above sea level. Most submerged volcanoes, however, are located on… View Article

Vulcanicity Case

Volcanoes mostly occur at plate margins. They can also occur at hot spots and in rift valleys. The most active volcanic zone is the Pacific Ring of Fire around the Pacific plate. Here plates are colliding or separating. At active points on these plates volcanic mountains are formed, e.g. Nazca Plate and South American Plate,… View Article

How does iceland utilise its volcanic activity

The first reason why Iceland utilizes its volcanic activity to its advantage is by using geothermal energy. Geothermal energy production works by the radioactive decay f several types of rocks containing radioactive substances (such as uranium) releasing heat energy. In the volcanic areas in Iceland, the rocks heat the water so that it then rises… View Article
