For which of the following problems would growing and maintaining cover crops be an appropriate solution? (2 points)
I. Erosion is thinning the soil on a farm.
II. The organic matter and nutrients in the soil on a farm are being depleted.
III. The soil on a farm is becoming arid due to slash and burn techniques.
II only
I and II only
I and III only
I, II, and III

Answers

Answer 1

Answer: I and II only

Explanation:

Cover crops are planted in order to protect the soil when the main cash crop is not being planted which means that they are not planted to be harvested and can be planted after the cash crop is harvested.

The two main purposes of cash crops are to protect the soil from erosion and to improve soil fertility. Their presence reduces surface runoff of soil when it rains and slows down rain before it hits the ground at force and splits soil.

Some cover crops are planted to improve soil fertility because they improve the level of nutrients in the soil and they can also be ploughed before they mature causing them to decay and add organic matter to the soil.

Answer 2

In order to maintain a crop cover, an appropriate solution would be to protect it from the erosion that leads to the thinning and also to protect the soil for the farm can be protected from aridity by the use of slash and burn technique.

The benefits of growing crops cover can be slowing the velocity of runoff and rain. Reducing the soil loss due to the sheet and erosion. Crops regimes can lead to an increase in the soil organic matter.

Hence the option I and III are correct.

marine organisms living in the water column are referred to as blank , whereas organisms living on or in the ocean floor are referred to as blank

Answers

Marine organisms living in the water column are referred to as pelagic organisms, whereas organisms living on or in the ocean floor are referred to as benthic organisms.

What is pelagic and benthic? Pelagic refers to living organisms that live in the water column, as well as the habitats and resources found there. Benthic refers to organisms that live in, on, or near the seabed or the benthic zone.

In general, pelagic organisms are those that spend the majority of their time in the water column, which is the region of the ocean that extends from the surface to the ocean floor. Pelagic organisms include zooplankton, phytoplankton, and other types of plankton.

These organisms drift with the currents and are found throughout the water column, from the surface to the ocean floor. Pelagic organisms are classified according to their size and the depth at which they live. Benthic organisms are those that live on the ocean floor.

Benthic organisms include coral, sea urchins, starfish, crabs, lobsters, and other types of bottom-dwelling animals. Benthic organisms are adapted to life on the ocean floor and have evolved to survive in harsh conditions, including extreme temperatures, low oxygen levels, and high pressure.

Benthic organisms play an important role in the ocean ecosystem and are often used as indicators of the health of the marine environment.

Why did Native Americans join the missions? What made the missions so destructive? What specific Spanish actions made the missions oppressive?

Answers

1. The various myths that Americans created about the mound builders were that the mound builders were not American Indians, but instead a lost tribe from another continent.

Some said that the mounds were built by European explorers from long before Columbus’s time. These myths were harmful for American Indians as they worked to erase the historical contributions of American Indians to North American culture.2. The Hopewell and Mississippian cultures defy traditional stereotypes of American Indians living north of Mexico in several ways. The Hopewell culture, for example, was a highly developed trading culture that constructed elaborate burial mounds.

The Mississippian culture was marked by large, walled cities with complex social and political structures. These cultures were significant as they showed that American Indians had complex societies with advanced technologies and that North America was not just a “wilderness” waiting to be tamed by Europeans.3. Native Americans joined the missions for various reasons, including the promise of food, clothing, and shelter.

However, the missions were ultimately destructive because they were designed to assimilate Native Americans into European culture and religion. The specific Spanish actions that made the missions oppressive include forced labor, beatings, and whippings, as well as the removal of Native American children from their families and communities to be raised in European-style boarding schools.

Answers

Responsibility for the incident falls on multiple parties. The tourist was directly involved, but the manager of Tourism and Economic Development and the mayor of Churchill also bear responsibility for ensuring the safety of wildlife and minimizing negative impacts on the environment.

What are the level of involvement of each category?

Category| Evidence of involvement |Stakeholders

Tourist (Social) | The tourist was in the tundra buggy that hit the polar bear. | Tourist industry, animal rights activists, local community.

Mayor of Churchill (Political) | The mayor has a responsibility to ensure the safety of both tourists and wildlife in the area. | Local community, animal rights activists, government officials.

Manager of Tourism and Economic Development (Economic) | The manager has a responsibility to promote tourism while minimizing negative impacts on the environment. | Tourist industry, local community, government officials.

Naturalists (Environmental) | Naturalists have a responsibility to protect the environment and wildlife in the area. | Environmental organizations, animal rights activists, local community.

Based on the evidence, it is clear that the tourist was directly involved in the incident. However, responsibility also falls on the manager of Tourism and Economic Development and the mayor of Churchill. Both have a responsibility to ensure that the tourist industry operates in a way that minimizes negative impacts on the environment and wildlife.

Furthermore, it is important to consider the impact on stakeholders. The local community relies on tourism for their economy, but they also value their wildlife and environment. Animal rights activists are concerned with the welfare of the polar bears, and environmental organizations are concerned with the impact of tourism on the fragile ecosystem.

In conclusion, responsibility for the incident falls on multiple parties. The tourist was directly involved, but the manager of Tourism and Economic Development and the mayor of Churchill also bear responsibility for ensuring the safety of wildlife and minimizing negative impacts on the environment. All stakeholders should work together to find a solution that balances the economic benefits of tourism with the need to protect wildlife and the environment.

on separate pieces of tracing paper, sketch the outlines of the continents of south america and africa found in figure 3.5. move the tracing papers until you get the best fit of the continents. how well do they fit together?

Answers

When looking at the outlines of South America and Africa on separate pieces of tracing paper, it becomes clear that the two continents seem to fit together quite well. This is because, millions of years ago, the two landmasses were actually part of the same supercontinent, known as Gondwana.

Over time, tectonic plate movements caused the supercontinent to break apart and the individual landmasses to drift apart. However, the outlines of the two continents still appear to fit together quite well, indicating their shared geological history. It is interesting to note that this phenomenon is not unique to just South America and Africa - other continents such as Australia, Antarctica, and India also show evidence of being connected to Gondwana at some point in time. Overall, the fit between South America and Africa is a fascinating example of how geological processes have shaped our planet over millions of years.

which of the following shoreline features is a result of erosion?

Answers

The shoreline feature that is a result of erosion is a sea cliff. Erosion is the process of wearing away the land, and sea cliffs are formed when waves erode and undercut the base of a coastal rock formation, causing the top to collapse and form a steep cliff face.

Other shoreline features, such as beaches and barrier islands, are formed by deposition, not erosion. Erosion is the process by which natural forces, like water and wind, gradually wear away rocks and soil. In the context of shoreline features, erosion plays a significant role in shaping the landscape.
Some common shoreline features that are a result of erosion include:
1. Sea cliffs: These are steep rock faces formed by the continuous action of waves eroding the coastline.
2. Sea arches: These are natural arch formations in coastal rocks, created when waves erode a weak part of the rock, leaving behind an arch-shaped structure.
3. Sea stacks: These are isolated columns of rock that remain standing after the surrounding area has been eroded by the sea.
4. Wave-cut platforms: These are flat, horizontal surfaces created when waves erode the base of cliffs, leaving behind a level platform.

In conclusion, the shoreline features that are a result of erosion include sea cliffs, sea arches, sea stacks, and wave-cut platforms. Please provide a list of options if you need a specific answer from a given set of choices.

“One thing that is poorly understood is population growth in Africa,” says William Cobbett, director of Cities Alliance . “It is thought that populations are growing mainly because of urban migration. That’s not correct. Across the continent, the bulk of population growth comes from natural population growth. Undesa figures from 1950-2050 show that in the case of Uganda – the outlier – its population in one century will multiply 20 times. That has never happened in human history.” Tanzania will grow 18 times and Nigeria 10.5.
“Most local authorities don’t have the capacity to deal with this, so there is no forward planning to make provisions for this population growth, which we know is going to happen.”
His organisation is trying to combat the mindset that you can’t plan for increased slum population, by supporting the creation of municipal development forums in a number of Ugandan cities. These are structured discussions where the local authority, local private sector companies and slum dwellers meet and deliberate about the future of the city.
Having the capacity to plan for future slum populations isn’t just a problem limited to Africa though.

a.hot spots
b.shield
c.volcanoes
d. calderas

Answers

Flood basalts are believed to erupt at hot spots directly over rising mantle plumes.
The correct answer is A. hot spots.What are flood basalts?A flood basalt is a vast volcanic province that forms when hot spot magma from the earth's mantle rises to the surface in a crack or fissure. In such an event, the fissure opens wide enough for a huge volume of lava to spew forth, covering a vast area with a layer of basaltic lava.Flood basalts are created by mantle plumes that travel through the earth's crust, causing widespread volcanic activity and fissure eruptions.

Because a mantle plume is stationary and the tectonic plates are moving over it, the movement of the tectonic plates over the plume can cause a variety of volcanic features, including hotspots. The hotspot theory suggests that flood basalts are the result of large-scale eruptions at the Earth's surface caused by rising plumes of magma from the mantle.

A) There are less than ten thousand people living in the country.
B) Slightly more girls than boys were born between ages zero and five.
C) The population growth steadily increases until age 30.
D) The country experienced a population "boom" in the last 5 years.

Demographers studying the current population of a particular country produce the age-structure diagram

Answers

Based on the age-structure diagram provided, conclusion Option C) The population growth steadily increases until age 30, which appears to be supported by the data.

This is because the diagram likely shows an increasing number of people in each age range from 0-5, 5-10, 10-15, and so on, up until the 25-30 age range, indicating a steady increase in population growth. This trend suggests that there has been a consistent influx of younger people into the country, either due to high birth rates or migration.

The other conclusions cannot be accurately determined from the diagram without more information. For instance, conclusion A) There are less than ten thousand people living in the country, cannot be confirmed without knowing the exact population sizes represented in the diagram. Similarly, conclusion B) Slightly more girls than boys were born between ages zero and five, cannot be determined without a clear distinction between the sexes in the diagram.

Conclusion D) The country experienced a population "boom" in the last 5 years, which is not supported by the diagram because the steady increase in population growth up to age 30 does not specifically indicate a sudden or rapid increase in population in the last 5 years. A population "boom" would typically be represented by a much larger spike in population in a specific age range, which is not apparent in the given data. Therefore, the correct option is C.

Answers

Tornadoes have a distinct signature on the radar screen, known as the "hook echo," which shows up as a region of rapidly changing wind directions within the mesocyclone.

The hook echo is a characteristic radar pattern that indicates the presence of a rotating thunderstorm and the potential formation of a tornado. It appears as a hook-shaped extension on the radar display, typically on the southwestern side of the storm. The hook is formed by the rear flank downdraft, which wraps around the mesocyclone.

The rapid change in wind directions within the mesocyclone, as depicted by the hook echo, signifies the rotating updraft associated with the tornado. The hook-shaped appendage is caused by the inflow of warm, moist air wrapping around the storm's updraft and intersecting with the downdraft.

Meteorologists use radar observations, including the detection of the hook echo, to issue tornado warnings and track the path of severe storms
