Answer:

Explanation:

Yes, the fundamental difference between these shades of quartz is in their mineralogy.

Pure quartz is made up of silica(SiO₂) in a framework silicate pattern. During the formation of these minerals, some other elements like certain metals can take up spaces in their lattices and crystal space. These other elements would serve as impurities in them and cause the different types of quartz we have. This is why some quartz appear rosy, some smoky, some milky e.t.c.

Answer:

The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.

Explanation:

The ruins of Pompeii are about 5 miles away from Mount Vesuvius. A mile equals to 1.609 kilometers. If pyroclastic surge travels in a straight line at constant speed, then the time (t), in minutes, taken to reach the site of the ancient Pompeii can be determined by the following kinematic equation:

t = \frac{x}{v} (1)

Where:

x - Travelled distance, in kilometers.

v - Speed of pyroclastic surge, in kilometers per hour.

If we know that x = 8.045\,km and v = 300\,\frac{km}{h}, then the time needed to reach the site of ancient Pompeii is:

t = \frac{8.045\,km}{300\,\frac{km}{h} }\times 60\,\frac{min}{h}

t = 1.609\,min

The pyroclastic surge would take 1.609 minutes to reach the site of ancient Pompeii.
