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.

Answer:
Dialogue between friends on Sustainable Development
A: Hello! How are you?
B: Very well. I am on my way to attend a seminar on ‘Sustainable development’ at the Institute.
A: Oh… What is sustainable development?
B: In a nut shell it may be described as economic development that is achieved without depleting the resources of nature.
A: That makes sense.
B: Another way of putting it is; using only what is required for sustenance.
A: Yes, there is abuse of resources these days. Over-production, over-consumption, just to name two.
B: I must go now or I will be late.
A: Okay, see you later.

Answer:
a. Secondary deviance is an eventual effect of primary deviance, where deviance begins.
Explanation:
In labelling theory, primary and secondary deviance are distinguished from each other. Primary deviance is considered to be the initial manifestation of deviance, while secondary deviance is considered the effect of primary deviance. These are also different in the way they are recognized. Primary deviance consists of deviant acts before they are publicly labelled, while secondary deviance occurs after diagnosis and labelling, and is often a reaction to the labelling itself.
Social critics like Charles dickens were different from romantic artists in that they wrote about society and not the individual.
Explanation:
The social realists of the 1850's came as a response of the Industrialization of England and their noticing of the ever increasing divide between the rich and the poor.
Romanticism too was an early response to industrialization but in a different vein.
It was about the assertion of individuality in the face of new developments in the society.
The social realists understood civil rights and living conditions of the poor as the paramount subject to write about as social injustice pervaded the society in Victorian England.
