Earthquake is when the ground beneath us starts shaking. An Earthquake is made up of two words- earth and quake. Quake means shaking. It is a natural disaster because it happens naturally.
It happens when the outer layer of the earth releases energy to the outside on which we live. It creates waves which make the ground tremble. Its intensity is measured in scientific ways.
Earthquakes are of different types and intensity. There are plates like things which are under the surface on which we live. They are known as Tectonic plates.
Sometimes these tectonic plates come in contact with each other which shakes the Earth. Also, when Volcanoes come out, an earthquake happens. When scientists test nuclear bombs, it also affects the earth deeply and causes an earthquake.
An earthquake has severe effects. It can occur any time so no preparation can be done suddenly to stop it. When it occurs, buildings start falling down and many people die under them. In the hilly areas, lands start sliding. They take away people and cars on the roads and everything gets crushed.
Earthquakes also cause fires because sometimes gas pipes are broken. When an earthquake happens inside the sea, it can cause a Tsunami. It sends high waves into the land due to which many people die and those areas near the sea are destroyed.
Earthquakes take away the lives, property and lands of people. Scientists have developed many technologies to know when an earthquake may come. There are many man-made reasons too due to which earthquake happens.
Question on Earthquake
What do you mean by an earthquake?
Earthquake is when the ground beneath us starts shaking. An Earthquake is made up of two words- earth and quake. Quake means shaking. It releases energy through seismic waves.
What is an earthquake in short?
Earthquake is shaking of the earth surface.
What are earthquake and its causes and effects?
Earthquake is shaking of the earth surface. An earthquake has many causes like tectonic plate movement, volcanic eruption, nuclear test, etc. When it occurs, buildings start falling down and many people die under them. In the hilly areas, lands start sliding.
