Schist is a medium grade sheet-like grain rock, whereas slate is hard and fine-grained rocks with a salty cleft that is caused by the formation of minerals as a result of the metamorphic of the grain ground rocks.
<h3><u>
What is slate?</u></h3>
- Through low-grade regional metamorphism, slate is transformed from an original shale-type sedimentary rock made of clay or volcanic ash into a fine-grained, foliated, homogenous metamorphic rock. It is the foliated metamorphic rock with the finest grain size.
- Foliation may occur in planes that are not parallel to the direction of metamorphic compression and instead line up with the original sedimentary layers.
- Slate's foliation is known as "slaty cleavage." Strong compression is what causes fine-grained clay flakes to grow back in planes perpendicular to the compression, which is what causes it.
- Many slates exhibit a feature called fissility when carefully "cut" by striking parallel to the foliation, with a specialized tool in the quarry. This results in smooth flat sheets of stone that have long been used for roofing, floor tiles, and other purposes.
Because of its extremely tiny grain size and flat grains, phyllite has a particularly sparkly texture. The largest grain size is seen in schist. Schists are made up of scales, whereas phyllite has a foliated texture.
- Muscovite and biotite are two minerals that are frequently found in micas and produce the parallel, extremely fine-grained flakes of rock that are seen in igneous rocks with feldspar and quartz.
- Phyllite, schist, gneiss, and slate are the rocks with the lowest grades, respectively.

The correct answers are C.) and D.)
The Continental Congress was a convention of delegates from the Thirteen Colonies who met May 10, 1775, in Philadelphia, Pennsylvania, soon after starting the fight in the United States War of Independence.
Their dress and demeanor were of great lawlords, which suggests a lot of wisdom, power and authority. <em>We know that there were only three well-educated delegates, who were William Brewster, William Bradfort, and Rev. John Robonson. </em>Therefore, all delegates wore their garments to be well treated and to convey security in their ideologies as well as their struggles for United States Independence.
