Anderson's model role if a factor, family, and community
Answer:
thanks
Explanation:
Final answer:
Anderson's ecological onion model emphasizes the importance of family and community actors in effecting change within societal systems, highlighting the significant role they play in individual development and the implementation of successful community programs that address issues like girls' empowerment.
Explanation:
Anderson's Ecological Onion Model and the Role of Family and Community
Anderson's model, often referred to as the ecological or onion model, is a framework for understanding how different societal systems impact individuals, such as girls in Senegal. This model suggests that to effectively promote change, family and community actors must be actively involved. Family and community are seen as critical to a person's development and socialization, influencing their views on religion, work, education, and overall behavior. Moreover, family roles and community involvement are fundamental in programs supporting girls' development, particularly in non-Western contexts where extended family networks are stronger and grandmothers, for example, play a significant role in child-rearing.
Interactionism adds another layer to understanding family dynamics, suggesting that familial roles such as the 'good father' are socially constructed and subject to change over time. Previously, a good father was seen primarily as a financial provider, but now the role includes the emotional and intellectual development of the children. This approach indicates the variability of family roles and their interpretation within societal norms.
Program designers must consider the familial and communal structures when targeting areas such as girls' education, health, and empowerment. Effective community programs employ an asset-based approach, respect cultural roles, and utilize adult education methods that promote critical reflection among community actors rather than coercion. Considering the various decision-making participants within the family and community is crucial for the success of development programs intended to improve the well-being of individuals within these systems.

Are there some cases where snow-free land and ocean surfaces seem to have similar albedos? If so, where, and what does the land surface most likely consist of in such cases?
Answer:
Explained
Explanation:
The Ocean surfaces have very low albedo because they reflect majority of radiations. Similar to ocean surfaces Forests also have low albedo( snow free surfaces)
The forest plants absorb the excess of radiations, ultraviolet rays for their Photosynthesis. And hence, lesser radiations are able to reach to the surface.
Of the different kind of forest cover The coniferous Forest the Albedo Similar to that the oceans 0.08-0.15 % in the summer.

Explanation:
Why does ocean temperature change little from day to night? Marine ice caps keep ocean water from heating up t0o much. Lesser cloudiness over the oceans allows them to soak up more solar energy than land. a. b. Salts in ocean water absorb sunlight during the day and release it at night. d. High heat capacity allows water to gain and release heat without much change in temperature
Answer:
D
Explanation:
Water has a high heat capacity. This means it takes much energy (compared to other elements and compounds) to raise the temperatures of water by a degree. This, therefore, means that during the day, the land becomes hotter faster than the oceans. (The reason for sea breeze during the day). Likewise, during the night it takes much time for the water to lose the heat and drop its temperatures (compared to land – the reason for land breezes at night)
Final answer:
The ocean temperature changes little from day to night primarily due to its high heat capacity. This means it can absorb and release large amounts of heat without a significant change in temperature. The correct option is d. High heat capacity allows water to gain and release heat without much change in temperature.
Explanation:
Water's high heat capacity is a defining characteristic that enables the oceans to moderate Earth's climate. This substantial heat capacity means that a significant amount of energy is required to change the temperature of a volume of water, which is why over 90% of the increased heat content of Earth is absorbed by the oceans. The rest of the energy is distributed amongst ice, land, and the atmosphere. Whereas land surfaces can experience extreme temperature fluctuations due to their lower heat capacity, water absorbs more solar energy and distributes this heat not only through the surface but also at greater depths due to light penetration and water mixing. This distribution, combined with the thermal inertia of such a vast body of water, means that ocean temperatures remain relatively stable, with minimal variation between day and night or even across seasons.
5. Suppose that every three months, on average, an earthquake occurs in a certain region. Assuming this is a Poisson process, what is the probability that the next earthquake occurs after three but before seven months?
Answer:
0.2709
Explanation:
Given that 1 earthquake occurs in 3 months
∴Number of earthquake that will occur in 1 month = 1 / 3
∴ The waiting time of the earthquake to occur can be shown as
[tex]X\sim exp(\frac{1}{3})[/tex]
And since it is a poisson distribution as mentioned, the waiting time is always exponential.
Now the probability of the next earthquake that will occur after three but before seven months is
[tex]P(3<X<7)=\int_{3}^{7}(\frac{1}{3})e^{-\frac{x}{3}}.dx[/tex]
= [tex]e^{-\frac{3}{3}}-e^{-\frac{7}{3}}[/tex]
= 0.2709
∴ The probability of ht waiting time is 0.2709
Probability calculations for earthquake occurrences over specific time frames.
The probability that the next earthquake occurs within the next three months: Since the average occurrence rate is every three months, this probability is the same as the average rate, which is 1. Therefore, the probability is 1. Given that six months have passed without an earthquake in Papua New Guinea, the probability that the next three months will be free of earthquakes: Since it has been six months without an earthquake, the probability of no earthquake in the next three months would also be 1.
Contrast the internal and external processes shaping Earth’s surface.
Externally, the forces that shape the earth’s surface are weathering and deposition. These are mainly powered by the sun. These forces are responsible for features such as ox-bow lakes and deltas. Internal processes include the convection currents of the mantle – that result in tectonic plate movements- and volcanic eruptions that are responsible for features such as mountains.
Internal processes shaping Earth's surface include plate tectonics and volcanic activities stemming from heat energy within Earth's core. In contrast, external processes, powered mainly by solar energy and gravity, influence the surface through erosion, weathering, and impacts from space projectiles.
Explanation:Internal and external processes play significant roles in shaping Earth's surface. Internal processes are driven by heat energy from the Earth's core and involve movements within the Earth's crust, mantle, and core. They include activities such as plate tectonics, volcanic eruptions, and earthquakes - all of which can cause changes like mountain formation, rift zones, subduction zones, and other geological activity.
External forces, on the other hand, are primarily influenced by solar energy and gravity. They include weather-related events like rainfall, wind, and temperature changes, which cause erosion and weathering of the Earth's surface. An example of an external change is crater formation, which occurs due to the impact of projectiles from space.
Summarily, while internal processes play a role in shaping Earth from within, external processes influence Earth's surface from outside.

Why do an overwhelming majority of scientist believe the current warming of the planet is because of human activity? Do you agree or disagree with this? Support your position with at least 3 forms of evidence from what you have learned in this lesson
The majority of the scientists believe that the humans are responsible in big portion of the global warming . The main reasons for this are the changes in the atmosphere because of the human activities, as well as the correspondence of the rise of the global temperatures with the development of the industry. Taking all things into account, it seems that the humans have effect on the global climate, and because of the enormous amount of greenhouse gasses that are released into the atmosphere, the temperatures are gradually rising. On the other hand, the global warming is also a natural process, so the major factors are still natural, not the human activity as it is often propagated, but the human activities are small portion that adds on the natural process. Evidence about this are the geologic records which show that the climate has been warming up naturally numerous times, the melting of the ice sheets are also good evidence about the warming of the climate, as well as the changing patterns of the climate across the globe.

Explain 3 reasons why death has a functional purpose from an ecological and systematic point of view.
Answer:
death allows for bacteria and fungus to grow on them, these are called decomposers.
They break down dead animals and plants and return vital nutrients to the soil.
Explanation:
Final answer:
Death has a functional purpose ecologically and systematically by redistributing resources, enhancing inclusive fitness and evolutionary benefits, and influencing societal and cultural evolution.
Explanation:
From an ecological and systematic perspective, death serves a functional purpose for numerous reasons. Here we explore three pivotal ones:
Resource Redistribution: Death allows for the release and redistribution of resources. When an organism dies, its body decomposes, enriching the soil with nutrients that support the growth of plants and provide food for a vast array of organisms. This process supports biodiversity and ecological balance.
Inclusive Fitness and Evolutionary Benefit: Certain species exhibit altruistic behaviors that include the death of one organism for the greater good of its genetic relatives. This concept, known as inclusive fitness, promotes the survival of related individuals, potentially increasing the frequency of shared genes within a population. Such self-sacrificial behavior can be viewed as contributing to the overall fitness of a species.
Societal and Cultural Evolution: Death plays a significant role in human societies by influencing cultural practices, religious beliefs, and social structures. It creates opportunities for individuals to pursue wealth and status, especially evident in rituals like funerals. These practices and beliefs surrounding death can encourage societal cohesion and cultural evolution.
These functional aspects of death in nature demonstrate its integral role in maintaining the balance and progression of life across different levels, from ecological systems to human societies.

In August 2012, tropical storm Isaac formed in the Caribbean and was headed for the Gulf of Mexico. There was an initial probability of .69 that Isaac would become a hurricane by the time it reached the Gulf of Mexico (National Hurricane Center website, August 21, 2012).
What was the probability that Isaac would not become a hurricane but remain a tropical storm when it reached the Gulf of Mexico?
Answer:
The answer is .31
Explanation:
The initial probability that tropical storm Isaac would become a hurricane was 0.69. We denote this event by A.
The probability that Isaac would not become a hurricane is the complement of event A, we denote the complement by Ac.
There are three probability axioms called Kolmogorov's axioms and from those axioms, we can deduce some useful rules for calculating probabilities.
This is one of them:
The probability of an event's complement (or the probability that the event will not happen) is 1 minus the probability that it will.
P(Ac)= 1- P(A)
P(Ac)= 1-0.69= 0.31

= [tex]10\times \frac{R^{2}}{\frac{3R}{2}^{2}}[/tex]
= 40 / 9
Therefore, pull on the satellite will be = Mg'
= 200 x 40 / 9
= 888.88 N
= 889 N
Pull on the satellite is 889 N

Why are metamorphic rocks so limited in their distribution at the Earth s surface?
Answer: Metamorphic rocks are formed by processes that take place in the depths of the Earth
Explanation: Metamorphic rocks are found in the depths of the Earth because they occur during the processes that take place there. This means that all types of rocks are not evenly distributed due to the processes they occur, so that some rocks, such as sediment, are more present on the surface and easier to find. Metamorphic rocks can reach and be found on the surface due to tectonic movements that push the rocks up. But still, these layers of metamorphic rocks that reach the surface are below some layers of other rocks. In order to find these metamorphic rocks on the surface, wind and water play an important role in the washing of the surface layers of rocks over the centuries, and thus make easier to find metamorphic rocks.

The Earth's magnetic field is generated by which layer? Select one: a. Outer Core b. Mesosphere c. Asthenosphere e. Outer core and Asthenosphere together Which layer(s) from the choices below are defined by physical properties and could be considered a brittle solid? Select one: a. Asthenosphere b. Mesosphere C. Asthenosphere &Mesosphere d. Lithosphere e.Mantle
1. a. Outer Core
The magnetic field of Earth is generated by the forces deep inside our planet. More specifically, it is the convection currents in the outer core layer that are managing to produce the magnetic field. These convection currents are made out of molten rock, and they are caused by the heat that is escaping the inner core and moves outwards toward the outer core. This process is called geodynamo, and its effects have big importance for the Earth and the living organisms on it, especially that the magnetic field of our planet also acts as a protector from the intense sun radiation.
2. d. Lithosphere
The only layer on Earth that can be described as brittle solid is the lithosphere. Unlike the layers that are deeper, the lithosphere is not as hot, nor has high pressure, so the rocks are in solid form, instead of being molten. This layer is also the smallest of all, and it is covering only the uppermost part of the planet. Apart from being the thinnest layer, it is also the layer that is composed of the lightest elements, as during the formation of Earth's layers, the heaviest elements were sinking to the center, while the lighter elements were pushed toward the surface.
Final answer:
The Earth's magnetic field is generated by the Outer Core (Option a). The layer(s) that are defined by physical properties and could be considered a brittle solid is the Lithosphere (Option d).
Explanation:
The magnetic field of Earth is a result of the movements within its liquid metallic outer core. This molten outer core, composed primarily of iron, moves and convects, setting up circulating electric currents which generate the magnetic field. On the other hand, the lithosphere comprises the crust and the rigid uppermost part of the mantle. It exhibits rigid, solid, and brittle characteristics, being easily cracked or broken, unlike the plasticity of the asthenosphere below it, which allows for fluid movement. These layers are crucial in the dynamics of plate tectonics, volcanism, and protection against cosmic radiation through the magnetosphere.
what is the absolute location of the Pacific Hinge region?
Answer:
The absolute location of Pacific Hinge region is from San Diego, California, USA at 2° 42' 55" N / 117° 9' 23" W , stretching to the Vancouver, west coast seaport in British Colombia, Canada at 55° 0' 0" N / 125° 9' 0" W.
Explanation:
The absolute location is the exact location of a place on earth and it is often given in terms of coordinates such as latitude and longitude.
The Pacific Hinge region is from the Mexican border to Vancouver and includes California and west half of Oregon and Washington.
The absolute location of Pacific Hinge Region is given by :
the region from San Diego, California, USA at 2° 42' 55" N / 117° 9' 23" W , stretching to the Vancouver, west coast seaport in British Colombia, Canada at 55° 0' 0" N / 125° 9' 0" W. Therefore, it is quite impossible to find the exact absolute location i.e. the latitude and longitude of the Pacific Hinge region.
The absolute location of the Pacific region is from San Diego, California, USA at 32° 42' 55" N / 117° 9' 23" W, all the way up to Vancouver, British Columbia, Canada at 55° 0' 0" N / 125° 9' 0" W.
This means that the exact latitude and longitude of the entire region are impossible to find, as it is a very large area. However, the above coordinates give a general idea of the region's location.
The Pacific region is a geologically active area, and is home to a number of volcanoes and earthquakes. It is also a major center for trade and transportation, and is home to some of the largest cities in North America.
