Earthquakes and Volcanoes

Extracts from this document...

Introduction

´╗┐Earthquakes and Volcanoes The 4 layers making up the Earth 1. The inner Core.This is the hottest part of the earth. It is solid. 2. The outer Core. This core is sorrounding the inner core. 3. The mantle.This is made up of semi- molten rock called magma. In the upper part of the mantle it is hard, but in the lower down it is soft and beginning to melt. 4. The crust is the outer layer of earth. It is the solid rock on which we live. It is divided into 2 : 1. The continental crust which carries land 2. The oceanic crust which carries water. ...read more.

Middle

Amongst those many gentle movements, occasionaly one may be violent. The movement of these plates boundaries can cause earthquakes and volcanic eruptions. The different types of plate movements 1. Constructive margins This is when two plates move away from eachother. Magma rises to fill the gap and forms new oceanic crust. This causes the formation of new volcanoes and earthquake activity. 1. Destructive margins This is when plates containing oceanic crust moves towards plates of continental crust. Where they meet there is a deep sea trench. This can be severe volcanic and earthquake activity. ...read more.

Conclusion

1. Turkey had it really bad and was called the Izmit earthquake. 2. Italy had its deadlies in Aquila 3. Greece also had a really bad earthquake. Beneficial aspect of volcanoes 1. The ash and lava of volcanoes break up into ferile soil. For example the slopes of Mount Etna are used for growing vegetables, peaches and apricots. It is also famous for olive, grapes and vine trees. The slopes of Mount Etna provide a soil which is rich in nutrients, south facing slopes to catch the sun and well drained soil. 1. Once the lava cools down, it forms a precious rock, the igneous rock. 1. Volcanoes may be used for geothermal energy and volcanoes make a great tourist attraction. ...read more.

    Hydroelectric power - The steep slopes and narrow valleys which limit farming, it is an advantage for hydroelectric power generation. Narrow valleys can more easily be dammed and the melting snow in spring increases the supply of water.

    granitic continental plates, it may cause partial melting of both mantle rocks and the plate rocks, producing magmas of varying silicity. Volcanic arcs forming near subduction zones, on the edges of continental plates, usually form high-silicity (high-viscosity) composite volcanoes. As for construction margins, the plates pull apart and "de-pressurises" the mantle beneath the plates and causes it to partially melt.
