Answer to Question 1

The seismic-moment magnitude scale measures the total energy released by the earthquake. This takes
into account the strength of the rocks, the area of a fault along which rupture occurs, and the amount of
movement of rocks adjacent to the fault. The Richter Magnitude Scale just measures the energy
released by the largest seismic wave



Answer to Question 2

The Richter Magnitude Scale measures earthquake magnitude, which is the total amount of energy
released by an earthquake at its source. This is a measure of the amplitude of the largest seismic wave
as recorded on a seismogram

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt. For the upper point of his scale, he used 96°, which he measured as normal human body temperature (we know it to be 98.6° today because of more accurate thermometers).

The cure for trichomoniasis is easy as long as the patient does not drink alcoholic beverages for 24 hours. Just a single dose of medication is needed to rid the body of the disease. However, without proper precautions, an individual may contract the disease repeatedly. In fact, most people develop trichomoniasis again within three months of their last treatment.
