According to speculation and study, what will happen to the global birth rate in about 40 years? (1 point)
Answer:
Decline
Explanation:
From the studies that have been done it is expected that the global birth rate will decline after 40 years. There are many reasons for this expectation, some of which are the development of the less developed countries, the people from the villages to move to the cities, more and more people to be out of the poor category, and focusing on careers as the countries develop. Some nations are still expected to have relatively high birthrates, but the majority of the countries will have significant drops in the birth rates, thus the global population will gradually start to slow down its growth, and further in the future stagnate, and probably starting to lower down gradually.
Which of the following statements best characterizes changes to agriculture in the United States since 1900?
A. Increased mechanization has reduced the need for labor.
B. Increased mechanization has increased the need for water, thereby increasing the need for labor.
Increased mechanization has increased the use of land, thereby increasing the need for labor.
D. Increased mechanization has increased food production, thereby increasing the need for labor.
Please select the best answer from the choices provided.
Answer:
D. Increased mechanization has increased food production, thereby increasing the need for labor
Explanation:
The agriculture in the United States has changed significantly during the 1900's. From being primitive in the manner in which the farming was done, the agricultural field became much more modernized. The new technologies had invented lot of mechanization specifically for this field, and that has helped a lot. The food production skyrocketed because the mechanization was making everything much more easy. The work on much larger areas was done much quicker, more efficient, and cheaper. That has resulted in much higher production of food, which in turn resulted in higher demand for labor force. The labor force in the agriculture though gradually has changed, as the Americans themselves started to avoid the farming, but the immigrants from Latin America welcomed the opportunity and gradually became the dominant labor force in this field.
Answer:
A. Increased mechanization has reduced the need for labor.
Explanation:
Before 1900 more Americans were engaged in farming and about 90 percent of the population are engage in farming. The farming was mainly for subsistence purpose to carter for the family. As the population increases more lands were used for farming .
During the 20th centuries industrialization and urbanization contributed to the progressive decrease in the number of individual engage in agriculture . This period the agriculture profession progressively became commercialized . Advances were made in the irrigation method. Gas geared tractor were engaged , commercial fertilizers rapidly increased in most farms . The transportation method improved also and this encourage commercialization farming in perishable goods.
The rural farmers and herders left their farms to seek job as the profession became more commercialize .
Generally, the increased mechanization reduces job as machine takes the place of humans labor.

put these ecosystems in order of least biodiversity to most biodiversity
1. Mediterranean forest
2. Indonesian rain forest
3. Arctic ocean
Answer:
1. Arctic Ocean
2. Mediterranean forest
3. Indonesian rain forest
Explanation:
The biodiversity of an ecosystem is directly connected with the living conditions in it. The Arctic Ocean, for example, has a very harsh climate. It is constantly winter, the temperatures a very low, and everything is covered in ice and snow. This has resulted in very limited biodiversity. The Mediterranean forests are part of the ecosystems in the temperate zone. This ecosystem has medium biodiversity, neither a lot nor little. It is an ecosystem that requires special adaptations, especially for the drought period and high temperatures, but in general it offers good living conditions. The Indonesian rain forests on the other hand, are part of the equatorial rain forests. They are constantly warm and moist, resulting in enormous amount of species of flora and fauna to be able to exist in them, ranking them as one of the places with the highest biodiversities in the world.

In the Horn of Africa and the Sahel, increased agriculture production has been unable to meet the demand of the increase in population for all the following reasons EXCEPT climate factors having limited the increase in agricultural production. governments having limited the incentive for increase by keeping prices low. this region traditionally having supported limited agricultural production. natural resources being unable to support enough of an increase in production. agricultural products failing to reach markets in saleable condition.
Increased agricultural production in the Horn of Africa and the Sahel has been unable to meet the population's demand due to climate factors, government policies, limited natural resources, and issues with product transportation and quality.
Explanation:The increased agricultural production in the Horn of Africa and the Sahel has been unable to meet the demand of the growing population due to various factors. Climate factors have limited the increase in agricultural production, as these regions experience unpredictable rainfall patterns, droughts, and desertification. Governments have also limited the incentive for increasing production by keeping prices low. Natural resources, such as water and fertile soils, are insufficient to support a significant increase in production. Finally, agricultural products often fail to reach markets in saleable condition, further impacting the ability to meet the population's demand.

Which type of plate boundary does the image show?
A. Divergent
B. Convergent
C. Fragmentation
D. Transform
The image shows the Convergent plate boundary.
Explanation:
Convergent boundaries occur wherever the Earth’s tectonic plates move or collide toward each other. As the plates converge, the denser, thinner tectonic plate sub-ducts or dives beneath the lighter, thicker, more buoyant tectonic plate.
As shown in the picture, the plates are composed of rigid lithosphere consisting of the crust of the earth and the uppermost mantle. Movement of the plates is driven by convection in the asthenosphere and lower mantle, which are softer and warmer than the lithosphere and can flow on geologic timescales. Convection is fuelled by heat generated from radioactive decay of elements in the Earth.
The type of plate boundary shown in the image is the Convergent plate boundary.
The Plate boundary is defined as the boundary edges where plates meets and moves apart, together or colliding. At the plate boundaries, activities like mountain, earthquakes, volcanoes do occur.
The 3 type of Plate boundary includes:
Divergent boundaries: It is where plates are moving apart.Transform boundaries: It is where plates slide passed each others.Convergent boundaries: It is where plates are colliding with each other..
Activities like strong earthquakes, volcanic mountains, islands are formed at the Convergent boundary when the sinking oceanic plate melts.
Therefore, the type of plate boundary shown in the image is the Convergent plate boundary.

A. The asthenosphere is denser than the lithosphere.
B. The asthenosphere has the same density as the lithosphere.
C. The lithosphere has the same density as the core.
D. The lithosphere is denser than the asthenosphere.
Answer:
A. The astenosphere is denser than the lithosphere
Explanation:
The theory of isostasy is a theory that suggest that the layers of Earth are arranged in accordance to their density. It is a theory that usually refers to the mantle and crust. The mantle (astenosphere) is denser than the crust (lithosphere), so the crust floats on top of it, depending on its density, with he continental crust being higher, while the oceanic crust being lower. The two forces that are responsible for this are the gravity and buoyancy.

Write a short paragraph of about 150-300 words. Explain how the physical environment can limit human activities.
Answer:
Explanation:
The physical environment is the part of the environment made up of both man-made and natural features. They consist of some physical factors like water, soil, e.t.c. Mountains, rivers, valleys, hills, dams, lakes all makes up the physical aspect of our environment and much more.
The physical environment can limit human activities in the following ways:
Barriers to communication and transportation: most times roads have to be cut through longer distances in order to bypass natural features like a huge mountains, a voluminous river e.t.c. This can severely impact the communication between places and people. Natural disasters: The physical environment can pose serious risk to humans through disasters such as earthquake, landslide, flooding, wildfires, e.t.c. Drought and famine: When several elements of the physical environment combines, they can lead to little to no rainfall for plant to thrive. This is very dangerous for life on earth. Human activities are connected a lot to how rich and useful a soil can be. Climate changes and global warming: Human activities are greatly impacted by changes in climate and weather. If too much rainfalls, it becomes a problem to farmers and human activities as a whole will suffer. If sunshine diminishes abnormally, the earth suffers as solar radiation is very key to life on earth.Answer:
Human activities affect the operation of physical environment processes, and the results rebound on the human world. The human factor is an important consideration in assessing climate, landform, and ecosystem changes. The physical environment provides resources and a platform to use those resources, but can also be a hazard to people. Therefore human impact as a subject is of special concern to physical geographers. This interest has developed from studying the impacts of the environment on human activities, to understanding the impacts of humans on the environment and attempting to reduce them. There is now overt recognition of the role of the human factor, wh ich is also reflected in an increase in applied work by physical geographers. The effects of human activit ies and physical environmental modifica tions range from being entirely local to global, and can be immediately evident or they may manifest slowly over time and become of concern at some time in the fu ture. The duration of the effects can be short-lived or everlasting. Many examples can be observed in our surrounding landscape. While this chapter describes and discusses only some of the impact of human presence in New Zealand, the conceptual context of humans as agents of environmental change
Explanation:
How does sea floor spreading relate to supercontinents?
The seafloor spreading occurs at the mid-ocean ridges. The reason for this is that the convection currents from the mantle manage to break through the oceanic crust and propel magma on the seafloor. As they do, the magma consolidated in the water and new crust is created. Since there's constant pilling up of new crust, it pushes the old crust away in both sides. This results in the movement of the plates, and as they move eventually they will come into a situation to collide, resulting in the continents to start merging with one another. As the continental masses merge, they will gradually create a supercontinent.
Answer:
Seafloor spreading is related to the existence of a super continents by the theory of plate tectonic.
Explanation:
Seafloor spreading is a process which takes place due to the divergent motion of plates, as a result of which the size of the ocean basin increases. The plate tectonic movement is responsible for the separation of the seafloor which over the millions of years, will subsequently lead to the formation of a single landmass. The earth initially comprised of a super continent named 'Pangea' which eventually split up, underwent evolution and created the present scenario.
Further explanation:
According to the plate tectonic theory, the earth's crust is comprised of numerous lithospheric plates. These plates constantly move over the less dense asthenosphere layer due to the generation of convection current in the mantle. These currents are initiated because of the heat energy radiated from the interior of the earth.
The asthenosphere is the layer that is present beneath the lithosphere where the rocks tend to flow during deformation.
Seafloor spreading takes place because of this plate motion. It occurs in the divergent plate boundary, thereby resulting in the addition of new materials to the crust along the mid-oceanic ridge. Due to this continuous plate motion, sharing a divergent, convergent and transform the type of boundary, all the landmass that is present on the earth's surface will again combine together forming a large continental landmass, similar to the Pangea that appeared about 350 million years back.
The super continent refers to the large continental landmass that is formed due to the accumulation of materials or sediments or the joining of smaller landmasses due to the motion of the plates.

All of the following are extrusive landforms except A. batholiths. B. lava plateaus. C. shield volcanoes. D. geysers.
Answer:
A. batholiths
Explanation:
The extrusive landforms are the landforms that have formed on the surface. On the other side, we have the intrusive landforms, being the landforms that have formed inside the crust. The lava plateaus are an example of extrusive landforms, as they have been formed on the surface by the cooling off of the lava flows. The shield volcanoes too are extrusive landforms, as they are clearly formed on the surface and lift up high in elevation. Even the geysers are extrusive landforms, as we can see, they are on the surface and propel the hot water on the surface. The batholiths are intrusive landforms though, as they form from the cooling off of the magma deep inside the crust.
Answer:
batholiths
