The sequence of increasing grades of metamorphism of a mudstone (shale, claystone, or siltstone) parent rock (protolith) is: slate (lowest grade), phyllite, schist, gneiss (highest grade).
1. Describe the change in grain size from slate to schist
2. How does the texture of phyllite differ from that of schist?
3. Why do you think that the micas (lat minerals) in these rocks are all parallel, r nearly so, to one another?
Answers
The slate is hard and fine-grained rocks and has a salty cleavage that is caused by the growth of minerals due to the metamorphose of the grain ground rocks while schist is medium grade sheet-like grain rock.
The texture of phyllite is very glittery as its a very fine grain size and the grains are flat. Schist has the greatest grain size. Phyllite has a foliated texture but schists consist of scale.Minerals like muscovite and biotite are common rocks forming minerals in micas and are found in the igneous rocks with feldspar and quartz, thus they are parallel and very finely grained flakes in the rock.Hence slate (lowest grade), phyllite, schist, gneiss (highest grade) rocks.

Geography and climate are important factors in forming a civilization. explain how this statement applies to the Indus Valley civilization?
Answers
Answer:
Hey there!
For geography: The Indus Valley civilization was built between the desert, mountains, forests. This caused the Indus Valley to have very fertile land, which was good for agriculture, and made the foundations of a good civilization. The deserts and mountains also provided a natural barrier between the Indus Valley and enemies.
For climate: The geography of the Indus Valley determined the climate, most notably the monsoon. The agriculture relied on these seasonal periods of heavy rain, which when used right, benefited the growing of crops. The rivers often flooded in the summertime, which was when the snow-capped himalayas melted.
Hope this helps :)
Answer:
Read Below
Explanation:
Geography and climate are important for many things. Just like now, planning ahead was never bad, and in fact there was nothing bad about it. Everyone knew that when starting something big, you have to have a plan. So, the location, the resources that are able to be used in that location, and then the readily available, easy accessible nature supplied things, were all taken to account on these types of builds. So with the Indus Valley Civilization, they took account of those measures, and made sure that the area could hold a village of people.
I mean they were so smart! They had the water source, the greenery, everything. They grew food like beans, wheat, barley, peas, and more. They had irrigated water into huge spring floods. That water from the Yellow River had be directed through the town and into the irrigate fields, which lessened the impact of damage that the floods could do. They build homes out of clay and brick, or sod. And they used the natural elements that they had. (Because they needed to)

What type of friction do the Nazca and South American plates have?
Answers
Answer:
Explanation:
The tectonic plates move among themselves as solid and rigid blocks, moving over the upper level of the mantle (asthenosphere).
When the plates get closer to each other, we say that they converge → ←, when they separate they diverge ← → and if what they do is move laterally next to each other they pass ⇅
In the case at hand, the Nazca oceanic plate converges with the South American continental plate, approaching each other at a rate of about 6 or 8 cm per year. And they have been doing so for at least the last 25 million years.
Since the Nazca plate, due to its composition, is denser than the South American plate, it has less buoyancy and when pushed against it, it folds and sinks towards the mantle where it melts. This process, called subduction, is responsible for the rising of the Andes, as well as the high seismicity and volcanism present along the South American west coast.
Answer:
Andes Mountains.

Based on the estimates of Alfred Wegener approximately when did the supercontinent called Pangea begin to split apart?
a. ~430 million years ago
b. ~350 million years ago
c. ~200 million years ago
d. ~50 million years ago
Answers
Answer:
Option: a. 200 million years ago
Explanation:
Million years ago, Earth had one supercontinent called Pangaea and surrounded by an ocean (Panthalassa). Alfred Wegener proposed the concept of one big continent after putting together different records of confirmation. He was able to give his theory by examining fossils of plants, trees, animals, and reptiles that found in different continents. About 200 million years ago, the supercontinent began to split up into two parts; Gondwana from Laurasia. Today's countries, including Africa, Antarctica, India, South America, and Australia are part of Gondwana, where Europe and North America from Laurasia.
According to Codd's rules for relational database design, it is often ideal and most efficient for a single database field to contain multiple data values.
A. True
B. False
Answers
Answer:
A. True
Explanation:
Dr. Edgar F. Codd was able to generate twelve (12) rules after his research on the Relational Database Model. One of his rules, the second one precisely which is the Guaranteed Access Rule specifies that 'all single database elements or values are most certainly guaranteed to be accessible through a combination of the primary-key model also known as the row value, the attribute-name also designated as the column value and the table-name. The information rule which is the first rule also specifies that all information must be represented as one value in rows and columns.
So, this implies that a single database field should contain multiple data values. He also mentioned that data cannot be accessed through any other means except for the above stated.

We live in diverse societies. It is normal for people to disagree about many
things, including religion and politics, but acceptance of the _____ can keep situations from becoming violent.
A. constitution
B. legitimacy of rule
C. legal charter
D. rule of law
Answers
Answer: D. rule of law
Explanation:
Socrates once said that humans without rules are nothing but animals. This is an apparent reference to the savagery of the animal kingdom that can see violence occur at the slightest provocation. The Rule of Law refers to the governing principle that everyone is subject to laws that were enacted to ensure that people live together in such a way as not to infringe on the rights of others and thus to prevent societal breakdown.
This is why a general acceptance of it can keep the general peace and keep situations from getting violent. For example, if two people got into an accident and could not agree on who was wrong, if there were no laws on how such an issue would be handled, there would probably be violence between the two. Granted violence might still occur but the incidence rate of this has been greatly reduced thanks to a general agreement to respect the rule of law.
Answer:
D. rule of law keeps situations from becoming violent
a sweater originally priced at $80 was marked down by 25% what was the price of the sweaterTerry earns $250 salary plus $5 per sale how many cells must Terry make to earn $765 altogether
Answers
Answer:
$60103 salesExplanation:
1. The sweater was originally priced at $80 and then got marked down by 25%. The new price is;
= 80 * ( 1 - 25%)
= 80 * 0.75
= $60
2. Terry earns a basic salary of $250 plus $5 per sale. To make a total of $765, from sales commission alone Terry must make;
= 765 - 250
= $515
Sales to make = 515/5
= 103 sales

Answers
Answer:
12.gon - An interior angle measures 150°
Called a Dodecagon, the sum of all of its interior angles is 1,800° therefore each individual angle is;
= 1,800/12
= 150°
15-gon - An exterior angle measures 24°
The sum of all the exterior angles of a polygon add up to 360 so a polygon with a 24° exterior angle is;
= 360/24
= 15°
16-gon - The sum of the interior angles is 2,520°
Known as a hexadecagon, each interior angle of this polygon is a 157.5° and when added up this comes to 2,520°.
18-gon - An interior angle measures 160°
The formula for calculating the interior angle of a polygon is;
Angle = (n−2) × 180° / n
160 = (n−2) × 180° / n
160n = 180n - 360
360 = 20n
n = 18
Other tiles
The sum of the exterior angles is 180º - all exterior angles must add up to 360º so this does not exist.
The sum of the interior angles is 2,160° - this is a 14 sided polygon which is not listed in the options.

A landowner who claims title to land deposited slowly by the action of a running stream would base such a claim upon:
Answers
Answer:
claim upon accretion
Explanation:
For moment to moment, when a rights of way scheme has been examined, it is found that the actual position of the current natural border of a land being invaded is not in accordance with the position of that border displayed in the map around which the designation is centred.
Where the variance in the position of the natural growing boundaries is due to either accumulation or an wrongly defined environmental boundaries on the map around which the title is centred, a land surveyor may proceed with an application under section 118 of the Land Title Law.

Because Iceland is part of the mid-ocean ridge, its composition is primarily basaltic, as would be expected of new oceanic crust. Based on your reading of the article and Essentials of Geology, explain why the magma encountered in the drilling was instead a rhyolite, which is more typical of continental crust. (Hint: what is the influence of partial melting on the magma composition
Answers
Answer:
Iceland lies very close to the ridge and rocks melt due to the competition of magma.
Explanation:
As Iceland forms a part of the mid-ocean ridge, it's composed mainly of the basaltic lava and the new oceanic crust is formed underneath this layer of crust as new lava spreads in both the sides if the mid-oceanic crust. The particle melting of the solid rocks is controlled by the three features of temperature, pressure, and composition. These generate the magma and decompress the melting, the rocks melt slowly and gradually and there is a change in volume.
