What are some advantages to an oligarchic form of government?
Answer:
Power is centralized within a leadership team, rather than involving everyone in every decision.
People can participate in activities, relationships, and work while the group in power handles the larger issues of the society.
An oligarchy strives to keep the status quo, which breeds conservatism instead of taking on risky ventures.
It can foster creativity and innovation because people are free from worries about running society.
Answer:
Oligarchy allows citizens to have the time to focus on their daily lives, more creative technologies to be created.
This is because oligarchy gives power to a group of experts which makes the government function properly .

Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and went extinct during the late Permian period (248 million years ago). On another site, the scientists find ammonites. Ammonites lived during the Mesozoic Era (245 to 65 million years ago) and are not found after that period. What can be concluded about the rock layers? Choose all that apply.
A The rock layers must have formed at the same time because they both contain biozones.
B The rock layer containing the trilobites must have formed before the one containing the ammonites.
C The rock layer containing the trilobites must have formed after the one containing the ammonites.
D The rock layers must have formed at different times because they contain two different biozones.
Answer:
A and C
Explanation:
The rock layers must have formed at different times because they contain two different biozones. The rock layer containing the trilobites must have formed before the one containing the ammonites. The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.
The rock layers must have formed at the same time because they both contain biozones. * This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.
The rock layers must have formed at different times because they contain two different biozones. * This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.
The rock layer containing the trilobites must have formed before the one containing the ammonites. * This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.
The rock layer containing the trilobites must have formed after the one containing the ammonites.
* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice
Which best describes the physical features of the Ridge and Valley region?
O It has scenic canyons and caves.
O It has the state's most important waterways.
O It includes the state's highest peaks.
O It includes a series of elevations and depressions.
mark this and ratum
Answer:
It includes a series of elevations and depressions.
Explanation:
Ridges are basically small elevations and if you look at them from a flat surface, they might even look like small mountains. In reality they are only 700ft tall.
Valleys on the other hand are plains with not ridges or small mountains.
Therefore a ridge and valley region would consist of a series of elevations due to ridges and depressions due to the plain valleys.
Answer:
D
Explanation:
The Ridge and Valley region is full of elevations and depressions. I also just had this on a quiz!
describe the difference in elevation and rock structure between a highland and a lowland
Answer:
High land is more eroded, lower land is less eroded.
Explanation:
highland has more erosion because the temperature is more on an extreme side, even though the rocks would be in well bigger pieces, in lowland there might be less elevation depending on the area, but the rocks would probably be a smaller size.
Who said that earth rotated about its own tilted axis?
Which processes produced heat that contributed to the formation of Earth's different layers? Check all that apply.
collision of materials
compaction of materials
cooling of low-density metals
radioactive decay
sinking of high-density metals
Answer:
a, b and d
Explanation:
it was correct on edge
The processes which produce heat that contributed to the formation of Earth's different layers include the collision of materials, compaction of materials, and radioactive activity.
There are three different layers that make up the Earth which are the mantle, the crust and the core. They are made of solid rock which is usually granite and basalt.The radioactive decay of the elements that are in the Earth's crust releases heat energy. It should be noted that about fifty percent of the internal heat that comes from the Earth is through radioactive decay.In conclusion, the correct options are A, B and D.

Which must be true for metamorphism to occur?
A. The parent rock must be in liquid form.
B. The parent rock must be igneous.
C. The process must take place underground.
D. The grain size must become smaller.
The parent rock must be in liquid form, must be true for metamorphism to occur. Hence, option A is correct.
What is parent rock?Parent rock is the fundamental rock that something else was produced from. It is mostly applied in the context of soil formation, where the parent rock typically has a significant impact on the final soil's composition.
Sandstone, shale, and limestone fall within this category. Metamorphic rock is the last type of parent rock. Extreme heat or pressure have resulted in the formation of metamorphic rocks. As a result, igneous or sedimentary rock changes in composition.
Thus, option A is correct.

What Are the (2) most important climatic factors for the Indian people?
Answer:
Latitudinal Location and Distance from the Ocean/Sea.
Explanation:
Latitudinal Location because it is the distance from the equator. The farther away from the equator you get, the hotter it gets, and vice versa.
Distance from the ocean/sea because the ocean/sea is a heat reservoir. It stores heat, and lets it out when its cool, therefore making places near the sea have either colder or warmer temperatures depending on the time of year.

There are different reasons for global warming. According to some scientists, increases in carbon dioxide levels are the cause of global warming.
How does carbon dioxide cause global warming?Due to CO2 and other greenhouse gases effect, there is global warming. This is mostly when CO2 is soaks up by infrared energy, it is said to vibrates and re-emits the infrared energy back in all directions.
Note that almost half of that energy goes out into space, and also an approximate of the same half of it returns to Earth as heat, thereby leading to the 'greenhouse effect. '

A republic is different from a direct democracy: In a republic, citizens elect representatives to pass laws and make decisions for them. Thus, option D is the correct option.
The way decisions are made is what distinguishes a republic from a direct democracy. In a direct democracy, decisions are made and legislation is voted on by the citizens themselves. This may entail events or meetings where everyone is given the chance to cast a vote on laws or policies.
On the other hand, under a republic, people choose representatives who act as their voice in government and enact laws. These officials are chosen through elections and given the power to speak for the interests of the people and make decisions in their place.
Thus, option D is the correct option.

In South China during the late Carboniferous period, was the air temperature warmer or cooler than the air temperature in the location today?
-Claim 1: It was warmer than it is today.
-Claim 2: It was cooler than it is today.
- Claim 3: No difference- the air temperature was the same as it is today.
Answer:
The correct option is:
1) It was warmer than it is today
Explanation:
Caboniferous period lasted from around 360 to 300 million years ago. The term Carboniferous means rich deposits of coal. The deposits of coals occured in different region of Europe, Asia and Africa, including South China. In the start of the period, the average temperate was 20°C° which was dropped to 12° in the middle of the period. This cooling and drying resulted in Carboniferous rainforest. Hence, the temperature was warmer than it is today.
