Answers

Answer:

A is to always near an ocean

B is to heat and rain

c is to heat and dryness

d is to ice year round

Explanation:

Im going to use the Koppen climate classification system. But first, some history. The Köppen climate classification is one of the most widely used climate classification systems. It was first published by the German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. So, there are many groups but im going to just do the basics. A is moderate because as you go near water, land attracts  heat more than water because of waters specific heat captivity. So the temperature is cooler than the land farther away from the ocean. B is heat and rain because that is typical weather in those areas. C is heat and dryness because there like no rain. Its all ways hot and dry. And finally, d. D is ice year round because its cold and that would make more sense .

Which is the best estimated pressure, represented in units of GPa, of the lower mantle? 110 GPa 220 GPa 305 GPa 360 GPa

Answers

The correct answer is A. 110GPa

Explanation:

Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.

In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.

Answer:110 GPa

Explanation: I took the quiz

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.

Answers

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

Both Newlands and Mendeleev organized elements into a table with rows and columns, but only Mendeleev named
different groups of elements.

Answers

The correct answer is B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.

Explanation:

Both John Newlands and Dmitri Mendeleev were relevant chemists, mainly known for designing the period table, which organized chemical elements. In the case of Newlands, he designed his period table around 1865 by organizing the known elements based on the atomic masses of elements (number of protons and neutrons); also, he divided elements into groups.

On the other hand, Mendeleev designed his periodic table around 1869; in this, elements were also arranged by their atomic masses, but Mendeleev considered the properties of each element such as electronegativity, which implied some minor changes in order, as well as leaving some spaces for elements that had not been discovered, but that Mendelev could predict. Thus, the option that compares the organization in both periodic tables is B.

Answer:

B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.

The correct answer is option A) Coastal erosions.

Coastal erosions affect the development of the Florida peninsula. Coastal erosion along the Florida coast is due to rising sea levels, natural disasters like frequent storms and hurricanes, numerous navigational inlets and other constructions, and poor developmental plans.

Why is erosion a problem in Florida?

In addition to increased hurricanes, storms, and sea-level rise, much of the beach erosion is caused by man-made activity such as the construction of jetties and seawalls and poor planning for coastal development along the shoreline.

What is Florida doing to prevent beach erosion?

The department's Coastal Construction Control Line (CCCL) Program protects coastal resources from improperly located and designed structures and activities that can destabilize the beach and dune system, cause erosion, expose an upland property to storm damage or interfere with public access.

The current owner has offered to lease the land to the county for 20 years in return for a lump-sum payment of $1.1 million, which would be paid at the beginning of the 20-year period. The agency has estimated that the land would generate $110,000 per year in benefits to hunters, bird watchers, and hikers. Assume that the lease price represents the social opportunity cost of the land and that the appropriate real discount rate is 4 percent.a. Assuming that the yearly benefits, which are measured in real dollars, accrue at the end of each of the 20 years, calculate the net benefits of leasing the land.b. Some analysts in the agency argue that the annual real benefits are likely to grow at a rate of 2 percent per year due to increasing population and county income. Recalculate the net benefits assuming that they are correct.c. Imagine that the current owner of the land was willing to sell the land for $2 million. Assuming this amount equaled the social opportunity cost of the land, calculate the net benefits if the county were to purchase the land as a permanent wildlife refuge.
