In a paragraph of not more than 8 lines describe the reasons for the difference in the population density of South Africa and England.​

Answers

Hey there! I'm happy to help!

Both South Africa and England have a similar populations. However, these countries have different population densities. Population density is how crowded the country is with people. South Africa is a much larger country in terms of its area while England has a smaller land area. If they have similar populations, but different amounts of space, one is going to have a higher population density. Since England has less space, it has a higher population density as there are more people in a smaller space. There is more land area in South Africa, so this naturally makes it less crowded.

The population of France is 63.7 million people. If the birth rate is greater
than the death rate, how will this affect the population

Answers

Answer:

The population will increase

Explanation:

In a given year if a country has more births than deaths, that means that there will be an increase in the total amount of people a country has. If this trend continues the population will grow in the future. If the birth rate is substantially higher than the death rate than the population will increase more rapidly, and more substantially. If the birth rate is only slightly greater than the death rate the population will still increase, albeit more slowly, and less substantially.

Answer:

Overpopulation can be an issue if it continues.

Lack of resources (food, houses, etc) can be a subject of concern because of the larger number of citizens.

Larger population and a Natural increases in population size will be noticed.  

Government might give out free contraception to its citizens to stop the increase.

Explanation:

Overpopulation will be possible because there are more babies being born that people dying. France's population can increase exponentially if this situation continues and doesn't reach a stop.

Natural increase in a population occurs when birth rate is greater than death rate. This can also lead to a Natural decrease, when death rate is greater than birth rate.

The increase can cause the government to hand out free contraception to people.

The lower death rate could have been the result of good health care in the country, which means the population is taken care of. So it isn't necessarily a negative thing.

Imagine that an impact occurred on the continental plate millions and millions of years ago, leaving behind an impact crater near the right side of the base of the volcano. Why would there be little evidence of this impact crater found today

Answers

Answer:

erosion would erode the surrounding area making less obvious and filled in by hardened magma leaving volcano over millions of years i think. Would leave little impact of the crater. Also growth of plants over years in ash-rich, fertile soil

Explanation:

Volcanic craters may be connected with a cone or flanks. Flows may also be present. Impact craters can be distinguished from volcanic craters by having center peaks, ejecta, high rims, and floors that are lower in elevation than the surrounding topography.

What is a volcanic crater called?

A caldera is a depression formed when a volcano's magma chamber is emptied in an explosive eruption. Without any structural support below, the terrain surrounding the erupting volcanic vent or vents collapses internally, forming the bowl-shaped caldera.

When an asteroid or meteorite collides with the surface of a bigger solid object, such as a planet or moon, an impact crater is generated. This item must be moving extremely fast—many thousands of miles per hour—in order to generate a proper impact crater.

define fertility management​

Answers

Answer:

Soil fertility refers to the ability of soil to sustain agricultural plant growth, i.e. to provide plant habitat and result in sustained and consistent yields of high quality.

Soil fertility is the ability of soil to sustain plant growth and optimize crop yield. This can be enhanced through organic and inorganic fertilizers to the soil. Nuclear techniques provide data that enhances soil fertility and crop production while minimizing the environmental impact.
Advancing food security and environmental sustainability in farming systems requires an integrated soil fertility management approach that maximizes crop production while minimizing the mining of soil nutrient reserves and the degradation of the physical and chemical properties of soil that can lead to land degradation, including soil erosion. Such soil fertility management practices include the use of fertilizers, organic inputs, crop rotation with legumes and the use of improved germplasm, combined with the knowledge on how to adapt these practices to local conditions.

The Joint FAO/IAEA Division assists Member States in developing and adopting nuclear-based technologies for improving soil fertility practices, thereby supporting the intensification of crop production and the preservation of natural resources.
Different approaches to efficiently manage soil fertility
An integrated soil fertility management aims at maximizing the efficiency of the agronomic use of nutrients and improving crop productivity. This can be achieved through the use of grain legumes, which enhance soil fertility through biological nitrogen fixation, and the application of chemical fertilizers.

Whether grown as pulses for grain, as green manure, as pastures or as the tree components of agro-forestry systems, a key value of leguminous crops lies in their ability to fix atmospheric nitrogen, which helps reduce the use of commercial nitrogen fertilizer and enhances soil fertility. Nitrogen-fixing legumes are the basis for sustainable farming systems that incorporate integrated nutrient management. Use of nitrogen-15 lends understanding of the dynamics and interactions between various pools in agricultural systems, including nitrogen fixation by legumes and utilization of soil and fertilizer nitrogen by crops, both in sole and mixed cropping systems.

Soil fertility can be further improved by incorporating cover crops that add organic matter to the soil, which leads to improved soil structure and promotes a healthy, fertile soil; by using green manure or growing legumes to fix nitrogen from the air through the process of biological nitrogen fixation; by micro-dose fertilizer applications, to replenish losses through plant uptake and other processes; and by minimizing losses through leaching below the crop rooting zone by improved water and nutrient application.
The contribution of nuclear and isotopic techniques
The isotopes of nitrogen-15 and phosphorous-32 are used to trace the movements of labelled nitrogen and phosphorous fertilizers in soils, crops and water, providing quantitative data on the efficiency of use, movement, residual effects and transformation of these fertilizers. Such information is valuable in the design of improved fertilizer application strategies. The nitrogen-15 isotopic technique is also used to quantify the amount of nitrogen fixed from the atmosphere through biological nitrogen fixation by leguminous crops.

The carbon-13 isotope signature helps quantify crop residue incorporation for soil stabilization and fertility enhancement. This technique can also assess the effects of conservation measures, such as crop residue incorporation on soil moisture and soil quality. This information allows the identification of the origin and relative contribution of different types of crops to soil organic matter.

which areas of Earth receive the greatest and the least solar irradiance?

Answers

Answer:

hope this helps

Explanation:

Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles

Answer: this is the answer

Explanation:

The regions closest to the equator receive the most direct sunlight because the light is arriving at an angle close to 0°. As a result, a lesser area is illuminated and so there is greater solar irradiance. The regions nearest to the poles receive sunlight at more of an angle, resulting in a larger area of illumination and therefore less solar irradiance.

7. Describe the difference between a command, a market, and a mixed economy. (3 points)

Answers

Hey there! I'm happy to help!

-------------------------------------------------------------------------------

COMMAND ECONOMY

A command economy is an economy that is controlled by the government or the state. The government dictates what will be produced, how much of it will be produced, and the method by which it will be produced.

This is the type of economy found in socialist and communist countries, where the government has much more power to plan the economy to improve it for the citizens of the country. The means of production are collectively owned.

This economy can be found in countries such as China, Vietnam, Cuba, Venezuela, and Laos.

-------------------------------------------------------------------------------

MARKET ECONOMY

A market economy is one that is controlled by the customers and businesses. As a consumer, you vote with your dollars. If nobody buys a product that a company makes, the company will stop making that product. The companies individually decide what they will produce, how they will produce it, and how much of that thing they will produce.

This is the type of economy usually found in countries with a smaller government, where the government has less control of the economy and it is controlled by the people, companies, entrepreneurs, etc.

This economy can be found in countries such as the United Kingdom, Australia, Singapore, Canada, etc.

-------------------------------------------------------------------------------

MIXED ECONOMY

A mixed economy is a hybrid of command and market economies. What happens is that there are government has control over goods and services in the economy via things like higher taxes, welfare distribution, etc.

The government also can control companies to some degree with regulations. It isn't necessarily socialist or communist as the government doesn't have complete control, but it does have more control over the economy, and this tends to fall on a spectrum. Mixed economy can be an umbrella term for different combinations with companies and the government.

Examples of countries with mixed economies include France and the United States.

Which layer of Earth experiences the least amount of pressure?

Answers

The Crust is the layer that experiences the least amount of pressure

Answer: the crust.

Explanation: Because the crust does not have to support as much weight. For example, if you were to say the layer closest to the center of the Earth experiences the least amount of pressure, that would not be true because the layers closer to the center of the Earth have to support even more weight above them then the layer farthest out.
