The Causes And Types Of Earthquakes On The Earth

Earthquakes: The Same Effects, but Different Responses Earthquakes occur as a result of the abrupt release of energy in the Earth’s crust that creates a series of waves known as seismic waves. Earth quakes greatly affect people whether they are living in economically disadvantaged countries or in economically developed countries. However, the way each of them responds to the hazard is different. The tectonic movements in the earth’s crust are the initial causes of earthquakes. These movements bring

Introduction An earthquake is the shaking of the earth’s surface, resulting from the sudden release of energy, which creates seismic waves within the earth’s lithosphere. One of the most dangerous and most destructive natural occurrences on Earth is known as earthquakes. Earthquakes are sudden violent shakings of the Earth’s ground. Earthquakes are sudden vibrations in the surface of the Earth caused by the force and pulling of rocks between faults. Each earthquake is different and can range in size

Introduction and Background: The word geo-hazards come from two words ‘geo ' formed from the word ‘geological’ which means from the earth and ‘hazard ' which is a situation that is bound to pose a risk to property, the environment or life. It is, therefore, a geological condition capable of causing damage. Geo-hazards are geological or environmental situations that comprise of both long and short term geographical progressions. These hazards can be fairly small featured, butcan also be magnified

| Lithosphere | Ecology (NASC 1093) | | The Lithosphere * The lithosphere is the hard shell of the Earth, consisting of the crust and the topmost part of the upper mantle. * It is a relatively thin layer, about 31 to 62 miles (50 to 100 km) thick under the oceans and 93 miles (150 km) thick on the continents. * It contains the minerals, rocks and soils that humans have used for building materials, metals and agriculture. * This layer is composed of the upper crust, about 3 miles

to some kinds of natural disasters, such as earthquakes and volcanoes that I learned in Geology class. No one will recognize that the Hawaii is the island most likely to feel it. Volcanoes and earthquakes are natural hazards in Hawaii especially earthquakes that have great destructive potential and its have destroyed many other places in Hawaii and killed hundreds of people. There are many differences between volcanoes and earthquakes. These two types of natural disasters can compare or contrast

Reasons of Earthquake and its consequences Earthquake is one of the greatest natural disasters. Almost every year around the world earthquakes occur and cause a lot of loses of lives and wealth. Earthquake can’t be prevented and predicted and these are the reasons why it is the most devastating one. Only one way of minimizing its effects is to be careful about its’ reasons and consequences. Throughout this whole composition reasons and consequences of earthquakes are described. Introduction:

ask: What is an earthquake? The sequence of events in an earthquake. What are the effects earthquakes have on land and people?   What is an Earthquake? An earthquake is when the ground violently shakes causing damage and harm to objects, people and infrastructure around it. An earthquake occurs because our earth’s crust is divided into big sections called tectonic plates. The gaps separating different plates are called fault lines and plate boundaries and this is where earthquakes are more likely

Natural disasters affect millions of people globally every day. Earthquakes are one of the most powerful natural disasters that inflict damage on our environment and in turn cost trillions of dollars every year. To respect the power of earthquakes we must first understand their cause, how they differ from biological energy, where they happen, the types of damage they cause, how we can predict them, and how we can safeguard ourselves against them. Living in known seismic zones is dangerous and can

The earth is made up of land masses under the crust called tectonic plates. These tectonic plates sit on the upper mantle and lower crust also known as the lithosphere. Tectonic plates are always moving because of the magma churning underneath them in convection currents. Because the tectonic plates are always moving it can cause plates to run into each other which means that one must give way to the other and slide under this can create mountain ranges as the pressure has to do somewhere, this is

Cause of earthquakes: Earthquakes are caused by the movements of the earth. Large blocks of stone called tectonic plates are constantly moving creating friction and stress with each other. These earthquakes then cause massive damage above the surface. There are three different types of earthquakes. Convergent: This occurs when two plates crash into each other from separate directions, this sudden crash lasts until one plates goes over the other, this is called a thrust movement. Over millions of
