what features in the the sedimentary or volcanic rock would you look for to tell u overturne limb

Answers

The following are the features in the sedimentary or volcanic rock that would be looked for to tell overturned limb:

1. Sedimentary rock

In sedimentary rocks, the upper surface is usually a layer of rock that has been eroded and exposed. This is commonly referred to as the "upper bed." The lower bed is located beneath the upper bed and is typically more resistant to erosion. The degree of weathering of the two beds can be used to determine whether or not a rock formation has been overturned.

2. Volcanic rock

In volcanic rocks, one can look for fractures and other structural features that may indicate that the rock has been overturned. Another method used to determine whether or not a volcanic rock has been overturned is to look for the presence of vesicles.

Vesicles are gas-filled cavities that are formed during volcanic eruptions. They can be used to determine the orientation of the rock formation.

which of the following territorial forms does not typically contribute to difficulty in national governance? please choose the correct answer from the following choices, and then select the submit answer button. answer choices an elongated state an approximately hexagonal or circular state an exclave a fragmented state consisting of multiple islands

Answers

The correct answer is an approximately hexagonal or circular state. This type of state does not typically contribute to difficulty in national governance because it is less likely to have long and difficult to control borders, and its central location makes it easier for the government to govern.

Additionally, its population will typically be more centralized, which makes communication and governance easier.

In contrast, an elongated state, an exclave, and a fragmented state consisting of multiple islands can all contribute to difficulty in national governance.

An elongated state can have long borders and may be difficult to defend and patrol. An exclave is a territory which is disconnected from the main state and therefore more difficult to control and govern.

Lastly, a fragmented state consisting of multiple islands is challenging to govern as communication and travel between the islands is more difficult.

In conclusion, an approximately hexagonal or circular state does not typically contribute to difficulty in national governance, whereas the other three forms can present a challenge for national governance.

In weighing the benefits cities derive from gentrification against the social and human costs, where do you think the balance lies?

Answers

The question of whether gentrification has a net positive or negative impact is a subject of much debate and there is no clear consensus on where the balance lies.

On the one hand, advocates of gentrification argue that it can bring economic growth, investment, and revitalization to previously neglected areas, leading to improved public services, infrastructure, and amenities. Gentrification can also lead to greater diversity, as more affluent residents move into previously homogeneous neighborhoods, and can create a sense of community pride and engagement.

On the other hand, critics argue that gentrification can also have significant social and human costs, including displacement of long-time residents, loss of affordable housing, and exacerbation of inequality and social division. Gentrification can also lead to cultural erasure, as traditional neighborhoods and cultures are replaced by more homogenous and commercialized environments. Additionally, the process of gentrification can sometimes be accompanied by exploitation, harassment, and discrimination against existing residents.

Overall, the answer to where the balance lies depends on various factors, such as the specific context of the neighborhood, the extent of displacement and loss of affordable housing, and the strategies employed to mitigate the negative impacts of gentrification. Ultimately, the goal should be to find a balance that supports economic growth and development while also prioritizing social equity, diversity, and inclusion.

Looking at the VEI, please discuss the relationship between frequency and classification of volcanoes.

Answers

The Volcanic Explosivity Index (VEI) is a method used to classify and quantify the size of volcanic eruptions. It is based on how much material is expelled, how high it is ejected, and how long the eruption lasts.

The VEI ranges from 0 to 8, with 8 being the most explosive. The higher the VEI, the more frequent and violent the eruptions are. As the VEI increases, so does the frequency of eruptions.

VEI 8 eruptions are very rare, occurring once every few centuries, whereas VEI 4 eruptions occur between once every year to once every few decades.

The frequency of eruptions is also affected by the type of volcano. Stratovolcanoes tend to have more explosive eruptions than shield volcanoes. In general, the frequency of eruptions increases with the VEI classification. As the VEI increases, eruptions are more frequent and violent, and the potential for destruction is greater.

describe eac the 4 major types of irrigation.a.rank them from least amount of evaporative/runoff loss to most.

Answers

There are four major types of irrigation: surface irrigation, sprinkler irrigation, drip irrigation, and subsurface irrigation.

Surface Irrigation involves flooding fields with water and is the most common type of irrigation. It is less expensive than other methods, but is also the least efficient, with higher rates of water loss due to evaporation and runoff.

Sprinkler Irrigation uses a system of pipes and nozzles to spray water onto crops, allowing for more even water distribution and fewer losses due to runoff. This is the most efficient method, with the least water loss due to evaporation or runoff.

Drip Irrigation uses tubes with emitters and nozzles to slowly drip water directly to plant roots, and is the most efficient method of all with the least amount of water loss due to evaporation or runoff.


Subsurface Irrigation is similar to drip irrigation, but the water is injected directly into the soil below the crop roots, which reduces the amount of water loss due to evaporation or runoff.

what are the effects on metamorphic minerals and textures of temperature confining pressure and differential stress

Answers

Metamorphic minerals and textures are significantly affected by temperature, confining pressure, and differential stress. Temperature affects the rate of metamorphic reactions, which affects the mineralogy of the metamorphic rock.

High temperatures can cause dehydration, recrystallization, and metasomatism of the minerals. Confining pressure has an important role in metamorphism, providing the force to cause recrystallization and transformation of the minerals. As pressure increases, the minerals become more densely packed.

Differential stress affects the shape and size of the minerals and the overall texture of the rock. It causes minerals to become elongated and aligned in certain directions, creating a foliation. Additionally, differential stress can cause shearing and fracture of the minerals. The combination of temperature, confining pressure, and differential stress is important for understanding the formation of metamorphic rocks.
