Answer:
c. 1965-1970
Explanation:
It took over "2 million years" for the human population to reach 1 billion, but once it went past the 1 billion mark, it only took another 200 years for it to reach "7 billion". In the late 1960s, the "human population growth rate" had reached its peak where the population growth rate had gone above 2.5% a year in the developing countries. The population growth rate of the entire world had reached a little above 2% a year back then.how does flood water stay in one area because last time I checked nothing was holding the water in, and if the earth is round it should just spread out shouldn't it?
It could be that since there are "bumps" all around our surface. These "bumps" could potentially act like walls, keeping the water in one place.
Reason why flood water stagnant in same area:
A flood occurs when there is a excessive rain, breakage of dam, heavy climate change and speedy melting of snow or ice. Usually the flood water can be constrained in a particular place that can be in a crater surface. This is caused by improper drought management and and natural hazards.
Though the infrastructure development keep on improving, the drought management system remains the same. So, the flood water stays in one area even though the earth is round. The government should take steps to ensure the security of citizens by taking care of the flood water development.
It can be spread out or saved by rain water management system. If the flood water stays in one area that is dangerous and make you ill-protected to infectious diseases, chemical hazards, and injuries.
One thing that is causing increased pressures on the Ogallala Aquifer is the tendency of farmers to plant crops that require even more water than usual. Which of the following are "thirsty" crops that farmers have started planting? Select one: a. Cashews and Pecans b. Almonds and Grapes c. Grapes and Cranberries d. Cashews and Almonds
Answer:
d. Cashews and Almonds
Explanation:
The Ogallala Aquifer is an enormous aquifer located in the southwestern part of the United States. Despite having enormous amount of water, this aquifer is facing serious problems and its water levels are constantly going down. The main reason for this is the agriculture, or rather the type of plants that are planted in the region. The region is relatively dry, so instead of choosing plants that are suitable to the dry conditions, the farmers opted for the plants that are highly profitable, but demand lot of water. Some of these plants are the almonds and cashews, both of which demand lot of water, and on top of it, being grown in much warmer and drier conditions, means that they require even more water than usual.
Farmers planting water-intensive crops like almonds and grapes are contributing to the depletion of the Ogallala Aquifer, with the current usage rate being unsustainable as the aquifer recharges much slower than it is depleted. (option b)
One thing that is causing increased pressure on the Ogallala Aquifer is the tendency of farmers to plant crops that require even more water than usual.
Among the water-intensive crops that are contributing to the depletion of the Ogallala Aquifer are almonds and grapes.
These "thirsty" crops have been increasingly planted by farmers, but these choices are unsustainable considering the current rate of aquifer depletion, as the aquifer's water is being used up much faster than it can recharge.
Pivot to crops that require less water, such as milo, might be necessary to preserve the Ogallala Aquifer for continued agricultural use and municipal water supplies on the Great Plains.

Explanation:
Josh bought 800 plastic whistles to give away to the kids at a street fair. Some of the whistles were small and cost $0.50. The larger whistles cost $0.75. In total, he spent $550 on the whistles. How many of the small whistles did he buy?
Answer:
200 small whistles.
Explanation:
[tex]0.5s+0.75l=550\\s+l=800[/tex]
This is a system of equations for this problem, where s refers to small whistles and l refers to large whistles. The first equation represents the added costs of the whistles equaling the total cost, and the second equation represents the added amount of whistles purchased equaling the total amount of whistles.
To solve, simply isolate the second equation for l.
[tex]s+l=800\\l=800-s[/tex]
Next, substitute your new value of l into the first equation and simply.
[tex]0.5s+0.75(800-s)=550\\0.5s+600-0.75s=550\\-0.25s+600=550\\-0.25s=-50\\s=200[/tex]
Once complete, you'll have solved for your s value (200), which is your answer.
Final answer:
To determine the number of small whistles Josh bought, a system of linear equations is set up and solved, using the provided information about costs and total numbers.
Explanation:
The question involves solving a system of linear equations to determine the number of small and large whistles bought by Josh. Given that the small whistles cost $0.50 each and the large whistles cost $0.75 each, and Josh has bought a total of 800 whistles spending $550, we can set up two equations to represent this situation:
Let x be the number of small whistles and y be the number of large whistles.
Equation for the number of whistles: x + y = 800
Equation for the total cost: 0.50x + 0.75y = 550
By solving this system of equations, we can find the value of x, which represents the number of small whistles Josh bought.

How long did the precambrian eon last
Answer:
Precambrian. Precambrian, period of time extending from about 4.6 billion years ago (the point at which Earth began to form) to the beginning of the Cambrian Period, 541 million years ago.
Explanation:
Scientists believe that the earth is millions of years older than the oldest rocks found on its surface. One reason they believe this is because
There are several reasons as to why the scientists believe that the Earth is older than the age of the oldest rocks. One of those clues is that the oldest rocks do not correspond with the estimated age of the formation of the planets in the Solar System, thus the Earth as well. Another one is that the Earth was initially hot, gassy and liquid, and it took millions of years for it to cool off, so only after its surface cooled off enough, the Earth got its first rocks. The rocks are also not staying static, but instead they move because of the tectonic movements, so over the course of millions of years, they weather, erode, sink, subduct, all of which can wipe them off the face of the Earth, so the younger ones remain.
The age of Earth is estimated by radiometric dating techniques that measure the decay of radioactive isotopes in rocks. This method, coupled with other geological evidence, suggests that Earth is over 4.5 billion years old, with the oldest rocks found being around 4.404 billion years old.
Notably, evidence for an ancient Earth is found in rock layers or strata, which, akin to the pages of a history book, record past surface events. Embedded within these layers are fossils that trace the evolution of life from organisms that existed billions of years ago.
The technique known as radiometric dating is crucial in this determination. It involves measuring the decay rate of isotopes from their original 'parent' isotopes into 'daughter' isotopes. This decay occurs at a predictable rate, acting as an atomic clock that allows scientists to calculate the age of rocks, providing evidence that the Earth is over 4.5 billion years old.
Moreover, the oldest known rocks on Earth, found in Australia, are mineral crystals that are at least 4.404 billion years old. This signifies that, while Earth's surface rocks may be younger due to geological processes like erosion and recycling of crust, the planet itself must be older. Given that Earth cannot be older than the solar system, its age is estimated to be between 4.4 and 4.57 billion years.
Chemical rocks are formed by what grow out of solution?
Answer:
precipitate
Explanation:
Chemical sedimentary rocks are rocks that are formed as a result of precipiation of minerals from solutions. The solutions are usually derived from dissolved loads during erosion. When they get to basins where they settle and more materials are dissolved, the solutions becomes supersaturated. This implies that the solvent contains more than enough solute it can normally dissolve. In this regard, the solution would begin to crystallize and precipitates will form from the solution.
Examples of such rocks are gypsum, limestone, anhydrite, sylvite
Answer:crystals
Explanation:
Many species of this group perform the important role of making an essential nutrient available to other organisms and are therefore called .
Answer:
producers (autotrphs)
Explanation:
The autotrpophs, also known as producers, are the organisms that are the basis of all ecosystems. The reason for this is that they are the ones that are capable of [producing their own food. By doing so, they are the ones that produce energy, energy that is transferred through the trophic levels above them. This means that the producers provide the nutrition for all the other organisms, be it the primary or secondary consumers, and if they are eliminated, then the ecosystems will crumble and fall apart very quickly.
Final answer:
Many species that perform the important role of making an essential nutrient available to other organisms within an ecosystem are typically bacteria and fungi, known as decomposers or detritivores. These organisms are critical in nutrient cycling by breaking down dead organic matter and releasing nutrients back into the ecosystem for use by plants and other organisms. Specifically, they are integral to the cycling of nutrients like nitrogen and carbon, which are essential for the growth of plants and the overall health of the ecosystem.
Explanation:
In an ecosystem, plants play a pivotal role as primary producers, initiating food chains and encompassing organisms such as Allotropa, Matsutake, and tanoaks, which are primary producers and photosynthetic autotrophs. Bacteria and fungi, on the other hand, help in degrading organic matter, which complements the plants' role in nutrient cycling. For instance, fungi form symbiotic relationships with plants like the Matsutake mushroom, which forms mycorrhizal associations with trees, aiding in nutrient and water absorption.
These relationships between different species often result in coevolution, where two or more species reciprocally affect each other's evolution. This is seen in mutualistic symbioses in the lab, but can also be observed in parasitic symbioses, where both the parasite and the host may evolve traits in response to each other. Vitamins are also pivotal in nutrition; while some bacteria and archaea synthesize their own vitamins, others, especially multicellular organisms, rely on dietary intake to fulfill their requirements. Understanding these complex interactions and the roles of different organisms underpins the study of ecology and botany.
What was a negative consequence of industrial capitalism?
Answer:
•working poor
•factor workers
•lower class
Answer:
Some people criticize certain aspects of capitalism that, according to these critics, can be solved without abolishing capitalism.
The existence of an unequal distribution of wealth and power is criticized. Many Social Democrats want to reduce income differences through, for example, progressive income tax. According to these critics, very large income inequality is undesirable because of the negative consequences for social cohesion. "Wage slavery" is generated in this way, in which employees, although they are paid, have very low salaries, which only allow them to subsist to continue working and generating wealth for employers.
Companies concentrate on profitability, which according to critics leads to unsustainable behavior. For example, it is more profitable to have products produced in countries with low wages, with these being sold in richer countries. This requires a lot of transport and therefore more emissions, which could be prevented by producing goods in the vicinity where they are consumed.

Which of the major continental regions of the United States is best for farming?
The Great Plains is the best for farming.
Question:
Which of the major continental regions of the United States is best for farming?
(a)The Appalachian Mountains
(B) The Sierra Nevada
(C). The Rocky Mountains
(D) The Great Plains
Answer:
The Great Plains regions of the United States is best for farming
Explanation:
The Great plains are the best continental region for farming. Plains are rich in alluvial soils, these soils are formed by deposition of soil by the river over time. These soils are very fertile because they accumulate the runoff minerals from soils and make them nutritionally rich.
The availability of water in plains is more. These plains are covered with grasslands and steppes. It is extended into the Canadian region. The approximate area of these great plains is 13,00,000 square kilometres. States like Kanas, Nebraska, North Dakota and South Dakota are entire of these great plains.

. Which of the following are causing increased use of the groundwater supply? Select one: a. Laws against surface water use b. Climate change c. Lack of food sources d. Population decreases
Answer:
c. Lack of food sources
Explanation:
The groundwater has been used more and more around the world. There are large reserves of it, but in the past few decades the groundwater reserves have constantly been going down. The main reason for this is the lack of food sources. Because the global population is constantly on the rise, more and more food is needed, and in order to produce it, more and more farmlands are created. The increased number of farmlands means that more water is needed for irrigation, thus the groundwater reserves are the ones that suffer the most.
Climate change contributes to increased use of groundwater supplies by altering precipitation patterns and melting glaciers, leading to overuse, depletion of water resources, and saltwater intrusion. The option (B) is correct.
Climate change affects patterns of precipitation and accelerates the melting of glaciers, which leads to a greater reliance on groundwater resources. This exacerbates water supply problems, such as overuse of water resources, groundwater mining, salinization of freshwater due to drilling deeper wells, and the issue of saltwater intrusion in coastal areas.
Other contributing factors, not listed in the options, include population growth and associated increased demand for water, agricultural practices, and industrial uses.
All mass movement occurs on slopes. Without gravity, the material would remain in place and not move. True or false.
Answer:
True
Explanation:
The mass movements are representing movements of large masses of soil, also including rocks, water, biomass in them. These movements though need certain natural conditions so that they can happen. For a mass movement to occur, there has to be a slope, and under the influence of the gravitation, once the conditions are right, there will be movement downward until it reaches a flatter spot. If the terrain is flat, then a mass movement can not occur, as the gravitation is pulling the material down, so it will not be able to move. Also, if the gravitation is lacking, the material will not move anywhere, as without gravitation, there will be no atmosphere, and without atmosphere, there will be no agents to cause the mass movement.
Answer:
True
Explanation:
All the mass wasting process is associated with the principle of the gravitational controls and this principle is essential for understanding the process of the formation of the weathering and the soil erosion process and flowage of the material down the slopes of the hills or the mountain etc.As the steeper slopes are more likely to have the mass wasting and as compared to the gentle and more flat slopes. The rock falls, and the slumps and the debris flows are all examples of mass wasting. Thus all the falls, slides, creeps and flows occur due to the gravity of the earth and fluidity of the materials.is the physical process responsible for the movement of soil.
Answer:
Erosion
Explanation:
ANSWER:
Yes, the physical process is responsible for the "movement of soil". The physical process is called Soil Erosion.
EXPLANATION:
Soil erosion is the process of displacement of the soil in the upper part or layer of land. It is a natural process and it is caused by the water erosion, air or wind erosion etc. In dry climates, wind erosion is mainly responsible for occurrence of soil erosion.It is a physical process and often known as a form of Soil degradation.How was the Homestead Act of 1862 partially responsible for the Dust Bowl?
The homestead act of 1862 was partially responsible for the dust bowl because it gave 160 acres to any adult citizen as long as it was cultivated for 5 years, after 5 years of the 160 acres being cultivated they would give them the land.
Answer:
The Homestead Act of 1862 granted everyone permission to have charge of the government land up to 160 acres each for the purpose of farming. This led young, new and inexperienced farmers to perform futile agricultural activities that resulted in the rise of the Dust Bowl.Explanation:
The Homestead Act of 1862 allowed the individual settlers to carry out agricultural activities on lands up to 160 acres each. The settlers conventionally believed in the idea of 'rain follows the plow'. Tremendous agricultural activity with negligible or no rain at all loosened the soil in the region making it vulnerable to flow with the raging winds in the region causing dust storms to occur. Thus, the southern plains region later started being addressed as the Dust Bowl. While hiking in a rural area, you encounter a wetland and conclude that it's a swamp.

Which of the following factors is one of two that is usually most responsible for determining population growth?
O A
total number of people within a continent
OB. average number of people in a given area
O c. world's total population
OD.
average weight of people in a given area
Your question asks which answer choice is a factor that is responsible for determining population growth
Answer: B). average number of people in a given areaThe reason why "B). average number of people in a given area" is the correct answer because this is a factor that helps determine the population growth.
When experts find the amount of people in a given area, they can find how much the population grew in that area. They can also go to other areas and find the average number of people there and find how much the population grew.
They then could add up all of the growths in order to find the grand total of how much the population grew in all the areas combined.
By doing this, it makes experts jobs more easier and efficient to find the population growth.

what are some advantages to an oligarchic form of government
Oligarchy allows citizens to have the time to focus on their daily lives, more creative technologies to be created.
This is because oligarchy gives power to a group of experts which makes the government function properly .
Hope this helps!
Answer:
In an oligarchy the power is in the hands of a small group of people who belong to a privileged class. In ancient times it was the ruling caste that possessed the power monopoly: a hereditary social grouping that is separated from the rest of society by religion, kinship, economic status, prestige and sometimes even language. Such elites tend to exercise power in the interest of their own caste.
In an oligarchic form of government, the validity of the laws is based on the discretion (group willingness) of this closed elite. It is one of the five forms of state described by Plato, who identifies the oligarchy as the "bad" variant of aristocracy because the oligarchy only aims at favoring its own class.
Given this definition and the way in which they favor their social group, the oligarchies have few positive attributes regarding society in general and the state as a common whole. However, an advantage that these governments may have lies in the continuity of policies that, although they are aimed at favoring the elite, provide security to the remaining nations regarding their relations with the government, as well as with respect to the measures they will carry out. In this way, they provide stability and, if their policies are favorable to free trade, they can encourage foreign investments.
