Answer 1

The correct answer is 1 to 12.

Key Points

An Earthquake is also called a quake, tremor, or temblor.
It is the phenomenon of shaking of the surface of the earth that also create seismic wave.
- Seismic waves are the waves that travel through the earth's layer.
- These waves are the result of earthquakes, volcanic eruptions, magma moment, landslides, and man-made explosion.
The earthquake produce different types of seismic waves such as P wave, S wave, and Surface waves.
Seismic activity also increases due to global warming.

Important Points

The instruments used to measure the intensity of the earthquake are Seismograph, Ritcher scale, and Seismograph.

Ritcher Scale

- The Ritcher scale is also called a magnitude scale

- It was developed by Charles F. Ritcher

Mercalli Scale

- The Mercalli scale was developed by Giusseppe Mercalli.

- The scale ranges between 1 to 12.

Seismograph

- A Seismograph consists of a mass attached to a fixed base.

- The mass moves during the earthquake.
