The size of earthquakes is usually measured using the moment magnitude scale, which is a measure of the energy released. A. True
B. False

True

Explanation: Moment magnitude is used by the USGS- it is based on the total moment release of the earthquake. Moment is a product of the distance and the force. The moment magnitude scale gives an esitmate of the total energy released from the earthquake

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
