Continental drift is the movement of the Earth ’s continents relative to each other. The hypothesis that continents ’drift ’ was first put forward by Abraham Ortelius in 1596 and was fully developed by Alfred Wegener in 1912. However‚ it was not until the development of the theory of plate tectonics in the 1960s‚ that a sufficientgeological explanation of that movement was found. |Contents | | [hide] | |1 History

Introduction I’m going to talk about a tsunami which hit many places in Asia and some parts of Africa which left many homeless and Thousands dead. A tsunami is a giant wave of series of waves usually caused to be a volcanic eruption or earthquakes o the seabed. As the Tsunami travels through deep water‚ the wave may

Analyse the factors that cause differences in the hazards posed by volcanoes around the world (40 marks) Your main factors can be put into two simple categories. Human and physical. From there you can then further explore the factors. In my essay I will mainly focus on viscosity‚ location‚ settlement and perception and explore how the physical and human factors intertwine with each other through one simple idea that physical factors dictate the hazard while human factors exacerbate the hazard. From

TSUNAMI Introduction 1. Tsunami is a Japanese word meaning “Harbor water”. Tsunami is in most cases the result of sea-bed earthquake. The latest tsunami was the largest of its type since the magnitude Good Friday earthquake of Alaska in 1964. It took a death toll of about 200‚000 people and immense property. Since last 100 years‚ this has been the greatest disaster that the Asian region suffered. It measured 8.9 in the Richter scale and generated a gigantic tidal surge

each other they create a conservative plate margin. The relative movement is horizontal‚ and classified as either sinistral (moving to the left) or dextral (moving to the right). Along these margins crust (lithosphere) is not being destroyed by subduction‚ neither is it being created. There is no melting of rock‚ and‚ therefore‚ no volcanic activity or formation of new crust. Despite the absence of volcanic activity‚ these margins are tectonically extremely active and are associated with powerful
