What is the preface of earthquake?

Earthquake is one of the biggest natural disasters, which is caused by seismic waves. These are created with sudden release of energy in the Earth’s lithosphere. There are different types of earthquakes; (i) Tectonic Earthquakes.

What is earthquake introduction of earthquake?

An earthquake is a sudden movement of the Earth, caused by the abrupt release of strain that has accumulated over a long time. For hundreds of millions of years, the forces of plate tectonics have shaped the Earth as the huge plates that form the Earth’s surface slowly move over, under, and past each other.

What is earthquake for project class 9?

An earthquake is the shaking of the surface of Earth due to the sudden release of energy in the Earth’s crust, as a result, seismic waves (also known as S waves)are created. The seismic activities in an area determine the type and intensity of the earthquake.

What is earthquake explain?

An earthquake is the result of a sudden release of stored energy in the Earth’s crust that creates seismic waves. At the Earth’s surface, earthquakes may manifest themselves by a shaking or displacement of the ground. Sometimes, they cause tsunamis, which may lead to loss of life and destruction of property.

What is earthquake and its types?

There are four different types of earthquakes: tectonic, volcanic, collapse and explosion. A tectonic earthquake is one that occurs when the earth’s crust breaks due to geological forces on rocks and adjoining plates that cause physical and chemical changes.

What is earthquake Class 8?

Earthquakes: Are earthquake is a sudden shaking or trembling of the earth which lasts for a very short time. Earthquakes can cause immense damage to buildings, dams, etc. They may also cause floods, land slides, tsunamis and loss of life. It is caused by a disturbance deep inside the earth’s crust.

Where does an earthquake start activity?

The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. Sometimes an earthquake has foreshocks.
