A fossil found in a surface rock layer is of the same species as a fossil found in a deeper rock layer. However, the two fossils differ slightly in structure. What do differences in the structures of the fossils indicate?

Answers

Answer 1

Answer:

The slight differences in the structures of the fossils indicate that the species has been evolving and adapting to its environment.

Explanation:

When we think of fossil remains of species we often tend to think that it is a species that has gone extinct or has changed enough so that its descendents are nowadays classified as different species. While this is true in big portion of the cases, it is not true entirely, as there are numerous extant species from which there are fossils from hunderds of thousands of years ago or even millions of years ago, and the changes are so little that they are still the same species.

When such fossils are examined and compared to the living members of the species it is almost always noticed that even though they are both of the same species there are some slight differences in their structures. This is due to evolution, as the organisms are adapting to the new environmental conditions, so in order to be able to survive they experience some changes that will help them in that. An excellent example are multiple species of opposums that exist nowadays and have experienced only very slight and even unnoticeable structural changes for tens of millions of years.

What causes the pressure that allows diamonds to form in the mantle? A. The sun's gravity acting on Earth B. The weight of the rocks in the outer core O C. The weight of the rocks in the crust and core D. The weight of the rocks in the crust and upper mantle​

Answers

Answer:

D. The weight of the rocks in the crust and upper mantle

Hope this helps :)

The pressure that allows the diamonds to form in the mantle is due to rocks weight which is present in the crust and upper mantle. Thus option (D) is correct.

What is mantle?

There are three layers of the Earth which are crust, mantle and core. Mantle is the second layer of the earth.

Diamonds are created in the mantle, where they require high temperatures and pressures to do so. Volcanic eruptions cause these to rise to higher layers.

The downward pressure from the rocks in the crust is what generates the pressure. The variation in layer thickness causes the pressure to be unevenly distributed. Diamonds are therefore not very frequent. Thus option (D) is correct.

Answers

Answer:

Calgary - E

Hudson Bay - B

British Columbia - A

Quebec City - C

Ottawa - D

Explanation:

On the presented map we have the territory of Canada. Canada is the second-largest country in the world, and it is located in the northern half of the North American continent. Despite the huge size, the country has a pretty small population that is highly concentrated near its southern border. Being such a big country, Canada has multiple marking geographical features as well.

From what we have marked on this map, there are three cities, one province, and one major geographical feature. Calgary is one of the two biggest and most developed cities in Alberta. Quebec City is the capital of the province of Quebec, as well as being its center in any aspect. Ottawa, even though much smaller than multiple other cities, is actually the capital of the country. British Columbia is a province that occupies a big portion of western Canada, and it is a highly developed province. Hudson Bay is a major geographical feature. It is a bay that goes very deep into the interior of Canada and it is so large that most countries in the world are actually smaller than it.

What method of navigation was popular in early Oceania and relies on careful observation of the natural world?
(A) Celestial observation
(B) Global Positioning
(C) Wayfinding
(D) Inertial navigation

Answers

Answer:

Wayfinding was the method of navigation used across Oceania.

Explanation:

ouThe Polynesians, a people group that inhabited the islands of Oceania, have a reputation as historically being the best sailors and navigators. These people were able to discover pretty much every island in Oceania, and when taken into consideration that they tend to be hunderds or even thousands of miles away it is highly impressive with the methods and technology they had.

The method of navigation was wayfinding, complemented with oral transmission of information as well. Basically, the Polynesians used every aspect of nature possible in order to navigate, from the positions of the stars to ocean currents, wind patterns, etc. Their canoes too were built for fast and very efficient sailing, being very lightweight, pointy and elongated, and easy to control. There seems to emerge pieces of evidence that in this manner the Polynesians even reached the American west coast way before the Europeans did.

A. human-environment interaction
B. meteorology

Answers

Answer:

The geographer in the passage is focused on human geography.

Explanation:

Human geography is part of geography that focuses on humans, their activities in the environment (both natural and anthropogenic), their characteristics, movements, as well as the reasons for any of them. Not to be mistaken though, despite humans being in the center of this part of geography, everything is connected with physical geography in one way or another, thus there are a lot of connections between the two major branches of geography.

In this case, the geographer is gathering data about the migration of people from one country to another in a given time period, as well as looking for patterns in that time period to find out why is that the case. Basically, the geographer is researching human activity, from one human-based creation to another, but all of that happening in the physical sphere, thus it is of interest to human geography, but as mentioned it is easy to see that there is a connection with the other part of geography as well.

A.

B.
oil reserves in other nations getting completely exhausted.
C.
highest consumers of oil are also the highest producers.
D.
highest consumers of oil are not the highest producers.

Answers

Answer:

The dependence comes from the fact that the highest consumers of oil are not the highest producers.

Explanation:

The Middle East, as a region, has been blessed with reserves of oil. This is the natural resource for which there is the highest demand on the global market, so having it means that it brings a lot of benefits. The most obvious benefit is a lot of profit, but there is also the political influence because of the dependence of other countries on the resource.

The huge amount of profit complemented with having all major economies in the world (except two) highly dependent on oil from the Middle Eastern countries has led to a lot of looking through fingers situations. Almost all of the countries in this region tend to be among the worst when it comes to the violation of human rights, suppression, dictatorship, but all other countries turn their heads and there is no reaction because of how dependent they are on their oil. Also, the leaders of these countries are spreading out their influence in other countries by buying a lot of businesses, buying actions, sports clubs, or even finance political parties in order to make a stronghold, and so far they do it to great effect.

Write a paragraph in which you explain in order of importance at least two ways that urbanization affects South America’s environment. Why did you choose this order?

Answers

Early cities developed in a number of regions, from Mesopotamia to Asia to the Americas. The very first cities were founded in Mesopotamia after the Neolithic Revolution, around 7500 BCE. Mesopotamian cities included Eridu, Uruk, and Ur. Early cities also arose in the Indus Valley and ancient China. Among the early Old World cities, one of the largest was Mohenjo-daro, located in the Indus Valley (present-day Pakistan); it existed from about 2600 BCE, and had a population of 50,000 or more. In the ancient Americas, the earliest cities were built in the Andes and Mesoamerica, and flourished between the 30th century BCE and the 18th century BCE.

Ancient cities were notable for their geographical diversity, as well as their diversity in form and function. Theories that attempt to explain ancient urbanism by a single factor, such as economic benefit, fail to capture the range of variation documented by archaeologists. Excavations at early urban sites show that some cities were sparsely populated political capitals, others were trade centers, and still other cities had a primarily religious focus. Some cities had large dense populations, whereas others carried out urban activities in the realms of politics or religion without having large associated populations. Some ancient cities grew to be powerful capital cities and centers of commerce and industry, situated at the centers of growing ancient empires. Examples include Alexandria and Antioch of the Hellenistic civilization, Carthage, and ancient Rome and its eastern successor, Constantinople (later Istanbul).

The Formation of Cities

Why did cities form in the first place? There is insufficient evidence to assert what conditions gave rise to the first cities, but some theorists have speculated on what they consider pre-conditions and basic mechanisms that could explain the rise of cities. Agriculture is believed to be a pre-requisite for cities, which help preserve surplus production and create economies of scale. The conventional view holds that cities first formed after the Neolithic Revolution, with the spread of agriculture. The advent of farming encouraged hunter-gatherers to abandon nomadic lifestyles and settle near others who lived by agricultural production. Agriculture yielded more food, which made denser human populations possible, thereby supporting city development. Farming led to dense, settled populations, and food surpluses that required storage and could facilitate trade. These conditions seem to be important prerequisites for city life. Many theorists hypothesize that agriculture preceded the development of cities and led to their growth.

A good environment and strong social organization are two necessities for the formation of a successful city. A good environment includes clean water and a favorable climate for growing crops and agriculture. A strong sense of social organization helps a newly formed city work together in times of need, and it allows people to develop various functions to assist in the future development of the city (for example, farmer or merchant). Without these two common features, as well as advanced agricultural technology, a newly formed city is not likely to succeed.

Cities may have held other advantages, too. For example, cities reduced transport costs for goods, people, and ideas by bringing them all together in one spot. By reducing these transaction costs, cities contributed to worker productivity. Finally, cities likely performed the essential function of providing protection for people and the valuable things they were beginning to accumulate. Some theorists hypothesize that people may have come together to form cities as a form of protection against marauding barbarian armies.

Preindustrial Cities

Preindustrial cities had important political and economic functions and evolved to become well-defined political units.

Remember to check! y = x + 1 Dogs Make Life GreatLet's face it, they don't call dogs "man's best friend" for nothing. They are sweet, they love us, and they do work for us. There is simply nothing better than a dog. If humans have learned to survive against saber-toothed predators, stampeding herds, and enduring famine, dogs have been right there. As Robin to our Batman, as Scooby Doo to our Shaggy, dogs have been there through thick and thin in our darkest hours. After all we've been through together, how could anyone disagree that dogs are the best pet any human could have?First, we get massive health benefits from dogs. They calm us down when we are stressed. Countless service dogs are trained every year to go into nursing homes and other facilities to provide comfort to patients. These therapy dogs have been shown to lower blood pressure and calm distressed patients. Dogs also bring sweet, sweet bacteria into our homes. These bacteria help build our immune systems and make us healthier. Studies have shown that people with dogs get sick less often. In addition, growing up with a dog in your home may make you less prone to dog-related allergies as you grow up. Finally, because dogs need regular exercise, dog owners tend to be more fit than those who do not own dogs or own only cats.Second, dogs just make us happier. New studies have found a lower rate of depression in dog owners. In part because dogs force their owners to be more active, it is likely that dog-owners just cannot stay cooped up at home all the time. This activity level also makes it easier to meet people, stay socially engaged, and feel a sense of belonging. They are dependable friends as well, always ready with a sympathetic ear, a soft belly to rub, and a willing smile. If your day seems like a version of the zombie apocalypse, ten minutes of playing fetch will certainly keep those zombies at bay until you can get back in the game.Finally, it's all about cute. Sure other pets can be cute, but consider tail wagging. What other animal has such a universally understood expression of joy? How can you not give into that sweet face, holding a stick, waiting patiently to be taken out to play? And if you have any doubts, you must not have seen a dog rolling on its back, tongue lolling about, head swishing back and forth, scooting first one way and then the next as if competing in a silly worm dance.Many cat owners may argue with this position, but dogs really are the best companions. They bring joy, like a bluebird brings spring, or a rainbow brings a promise. They teach us about patience. They teach us about faith, waiting patientlyno matter how many times we leave without themfor that one time they get to load into the car and go with us. Always ready to go, always ready to wait longer, they make us hurry home at the end of the day for just a little unconditional love.Which line from "Dogs Make Life Great" best states its main point?
