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:
A reward system.
Explanation:
My parents use this system all the time and they say that it is called a reward system.
Answer: I would say up to a month or so im not sure
Explanation:
When given the chance to use a tool after observing someone else use it, chimpanzees raised by human surrogates are more likely to exhibit the method than those raised by their parents.
Since they have a human-chimpanzee link and pick up new skills from their surroundings, chimpanzees raised by surrogate mothers find it simpler to perform behaviors that have been done in front of them. However, chimps reared by their mothers lack these connections, which makes them act in a peculiar way. Chimpanzees raised by a surrogate mother will have higher developed intellects than those nurtured by their mothers since their upbringing will have a positive effect on their intelligence.
