Japan

japan is a mostly volcanic island located on an active plate rim. It be unyieldings to the fire belt, a chain of volcanic activity around the Pacific Plate.
japan is a orbit with a very steep relief, a mountain lay in the sea. The mountains argon formed by the collision of both plates. This results in stress in the rock, tectonic movements, earth quakes and volcanism.
The mountains argon composed of all types of rocks. Numerous volcanoes produced huge amounts of igneous rocks. in all kinds of sedimentary rocks, sandstones, cherts and limestones, deposited on the floor of the Pacific Ocean, where aggregated by the convergent movement and uplifted by the orogeny. There be in any case reef limestones, formed along the coast of Japan and later uplifted.

Several major tectonic lines run in the Japanese Islands, including the Median Tectonic Line, the Itoigawa-Shizuoka Tectonic Line, and the Tanakura Tectonic Line. These are long fault zones and b sanctifys geotectonically dividing the island arcs.

Volcanic activities are limited mainly in divergent and convergent boundaries of plates and hot spots.



For example, volcanoes of mid-ocean ridges are on the divergent boundaries, volcanic island arcs are on the convergent boundaries, and Hawaii volcanoes are formed on a hot spot. Since tectonic settings and the mechanics of magma generation are different among these regions, these produce varieties in the surpass of volcanic activity, magma characteristics, eruption types, and volcanic landforms. Such variations are also found within subduction zones and even in Japan.

Main islands of Japan are Hokkaido, Honshu, Shikoku, and Kyushu; Honshu is the biggest islands. Japan is divided into the Tokyo metropolitan stadium and 46 prefectures as administrative districts. It is also classified into 8 regions conventionally: from north, Hokkaido, Tohoku, Kanto, Chubu, Kinki, Chubu,...If you want to get a full essay, order it on our website: Orderessay
