Answer 1

Answer:

.

Explanation:

1. An earthquake is a sudden shaking or trembling of the earth lasting for very short time caused by a disturbance deep inside the earth. An earthquake may range from mild tremors that are not even noticed. to a large scale of movement of the earth causing a great damage over a large area . Major earthquakes are much less frequent. They can cause immense damage to buildings,bridges,dams and people.There can be a great loss of life and property . The earthquake can cause floods, landsides and tsunamis also.

It is measured by a richter scale.

Answer 2

An earthquake is a sudden shaking of the ground that is caused by the movement of seismic or tectonic plates.

Causes:

1. The main cause of Earthquakes is the movement of tectonic plates.
2. Earthquakes may be caused by human activities such as mining, tunnel construction etc.
3. Another cause of earthquakes is volcanic eruptions. These eruptions cause a disturbance in the earth's crust thereby leading to an earthquake.

Effects:

1. An earthquake affects human lives and may cause damage to infrastructure or natural habitats.
2. An earthquake may also lead to landslides and tsunamis.

How it is measured:

1. The study of earthquakes is known as 'seismology'.
2. The magnitude of seismic waves caused by the Earthquake is measured on a Richter scale.
3. For example, the Alaska Earthquake in 1964 and the Valdivia Earthquake were two of the most destructive earthquakes with a 9.2 and 9.5 magnitude respectively.
