A. Celsius scale
B. Kelvin scale
C. Decibel scale
D. Richter scale

Answer 1

Answer:

(D)Richter scale

Explanation:

Richter scale are used for measuring magnitude of an earthquake

Answer 2

The magnitude of an earthquake is measured on D. Richter scale

Explanation:

• The strength of seismic waves is measuring with Richter magnitude scale or Richter scale.
• It was developed by Charles F. Richter and it is denoted by ML or $\bold{M_L}$
• It gives the logarithmic value of original value and it need to be scaled to have numeric values.
• The Richter magnitude is given by the formula:

$M_{\mathrm{L}}=\log _{10} A-\log _{10} A_{0}(\delta)=\log _{10}\left[A / A_{0}(\delta)\right]$

• This formula is calculated with the amplitude of the waves.
• According to the effects of the range of waves, they are classified into many types.
