Question

Which statement describes the moment magnitude scale?
O It measures only small earthquakes.
It collects data using a seismograph.
It shows only the strength of seismic waves that were produced.
Olt determines the amount of damage caused by an earthquake.

ans- it collects seismograph

Answer 1

Answer:

As shown in the edited answer, the correct choice is B

Answer 2

Seismograph is used to record motion of Earth during occurrence of  earthquake. Moment magnitude scale collects data using a seismograph.

What moment magnitude scale?

The moment magnitude scale is referred to total moment release of the earthquake.

Moment is a product of the distance moved and the force required for it to move . It comes from modeling recordings of the earthquake at various stations.

Scientists using the moment magnitude scale to measure the earthquakes size till magnitude 9.5 which is the largest earthquake unit recorded since seismographs were invented.

Thus, the correct option is B.
