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

Answer 1

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.

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

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.

Andes Mountains.

Answers

The direction of movement of the tectonic plate that helps form the islands will be towards north west.

The Tectonic Plate  

The diagram shows a series of volcano islands, a hot spot where lava is present.

The coming of the two tectonic plates together is called convergent boundary.

The colliding of plates can create islands by overlapping one plate with the other.

The colliding result in mountain ranges on the mainland or islands in the middle of the ocean.

The other place will bend down into the seafloor.

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)

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.

Map of Waldron, AR: The rings of bedrock in this region are composed of alternating layers of mudstone and quartz-rich sandstone. Which one makes up the ridges (not the valleys)?


a. Mudstone

b. Quartz-rich

c. Sandstone granite

d. Schist

Answers

Answer:

b. Quartz-rich

Explanation:

In this map of Waldron, we appreciate ridges and valleys. We also know that the bedrock of the region is composed of mudstone and quartz-rich sandstone. The ridges are the ones that compose mountains, such as the Ouachita Mountains. The reason why these mountains are able to be created is because the bedrock is resistant to erosion. Mudstone is easily eroded, but quartz-rich sandstone is more resistant and thus can better stand erosion. Therefore, the bedrock that makes up the ridges is likely to be composed of quartz-rich sandstone.
