Answer: Sillimanite, Andalusite, Kyanite and Staurolite
Explanation:
This are the four main minerals that forms in metamorphic rocks and indicates metamorphism.
Sillimanite forms at a high temperature condition, andalusite forms at a moderate temperature and pressure condition, and lastly, kyanite forms at a high pressure condition. Staurolite also forms at high temperature-pressure condition.
This four minerals forms when a rock undergoes metamorphism and are usually found in metamorphic rocks such as schist, gneiss and granulite.
<u>Answer:</u>
<em>C) Population Density Equation </em>
<em></em>
<u>Explanation:</u>
Population density is the total population that has been divided by the total area of the land. "Demography" is the "statistical study" of populations. It includes the study of size, structure, and distribution of the population. There are both direct and indirect methods for the data collection. Direct data is vital that tracks all the births and deaths and also include the changes in the legal status such as marriage, divorce, and migration. On the other hand the "indirect method" is vastly dependent on the historical demography.
<span>Streams and creeks are examples of "watersheds." Aquifers and ground water are related to each other because both of them are located under the earths surface. You have to dig in order to acquire these two. Watersheds are just like catch-basins where waters are stored or being flowed.</span>
