1. What is mean by earthquake
2. State its disadvantages
3. State its causes
4. And what cure should we take during earthquake
Dear Student
Earthquakes are caused by disturbances deep down the uppermost layer of the earth known as the crust.
Causes:
The tectonic plates of the earth float over the hot magma below and are in relative motion to each other. When these plates collide and when the rocks at the joints are sufficiently slippery, the plates slide over each other. However, sometimes, the rocks at the joints get interlocked and struck, thus resisting pressure from within. For years, the forces pushing the plates build up until the strain rips the plates apart. As a result, the rocks crack and shift, sending shock waves in all directions. These waves reach the surface and are felt as tremors.
Precautions:
1. Emergency drills need to be practiced as a precautionary measure for Earthquakes.
2. In the earthquake prone areas, buildings should be constructed as per regulatory norms so that they are able to survive the tremors of the earthquake.
3. An emergency kit should be prepared and kept handy to be used in case of an earthquake.
Disadvantages:
1. Earthquakes cause loss of lives and extensive damage to the area where it occurs.
2. It may also trigger tsunami waves.
3. Electricity supply and water supply also gets disrupted.
