Question

question 49 2 pts which of the following materials is not a mineral? ice table salt talc sugar question 50 2 pts which of the following describes the size of an earthquake in terms of the energy released during the event and is calculated using the area of the rupture and the material properties of rock? richter magnitude moment magnitude mmi intensity

Explanation:

For Question 49, minerals are naturally - occurring, inorganic, crystalline substances. Sugar is an organic compound, so it is not a mineral. Ice, table salt (sodium chloride), and talc are minerals. For Question 50, moment magnitude describes the size of an earthquake in terms of the energy released and is calculated using the area of the rupture and rock material properties. Richter magnitude is based on ground - motion amplitude, MMI (Modified Mercalli Intensity) measures the effects of an earthquake at a particular location, and intensity is a measure of the effects of an earthquake on people, buildings, and the environment.

Answer:

Question 49: D. Sugar
Question 50: B. Moment magnitude
