Answer:
B.) magnitude
Step-by-step explanation:
The magnitude of an earthquake is a measure of the amount of energy released by the earthquake. The magnitude is typically expressed on the Richter scale, which is a logarithmic scale that quantifies the size of an earthquake based on the amplitude of the seismic waves it generates. The magnitude of an earthquake is a measure of the earthquake's size and power, and is not the same as its intensity, which is a measure of the earthquake's effects on a specific location. A seismogram is a record of the ground motion during an earthquake, as recorded by a seismograph. Force is not directly related to an earthquake.
