Answer:
The specific gravity of minerals will vary because of the presence of impurities in the minerals structure.
Explanation:
The specific gravity or relative density of a substance is a measure of the ratio of the density of a substance to that of the density of a reference substance, in this case, water is the reference substance.
Specific gravity measures how much heavier as substance is relative to water. Therefore, the specific gravity of a mineral is a measure of how much heavier it compared to the weight to an equal amount of water. The specific gravity of water is 1.0. If a mineral has a specific gravity of 4.5, it means that it is 4.5 times heavier than water. Different minerals have different specific gravities. Most minerals with metallic luster have high specific gravities and are known as heavy minerals. Some have average weights while some minerals are light minerals.
The specific gravity of minerals will vary because of the presence of impurities in the minerals structure. If a light mineral is present as an impurity in a heavy mineral, the specific gravity of that mineral will be less than the pure mineral and vice versa.
Answer: True
Explanation:
The ratio of the map distance to ground distance usually involves the use of inverse relationship between the extent of coverage of the entire map and the amount of detail visible. And this relationship is always written as 1/x or 1:x.
Where the numerator represents the map distance which always equals 1 and the denominator represents the ground distance which has similar units as the numerator.

Hello!
I believe that Tanzania produces the most gems. Tanzania is one of the most important countries for gem production. Some gemstones that have been found include Ruby, Sapphire, Garnet, Alexandrite, Emerald etc.
I hope this helps!
