Why do we see different shapes of moon ?

Answers

Answer:

The phases change as the moon revolves around Earth, different portions of the moon's sunlit surface are visible from Earth.

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.

In 1980 there was growing concern that the protective ozone layer over the Antarctic might be decreasing and thereby allowing so much harmful ultraviolet radiation to reach the Earth that polar marine life would be damaged. Some government officials dismissed these concerns, since statistics indicated that global atmospheric ozone levels remained constant. The relevance of the evidence cited by the government officials in support of their position would be most seriously undermined if it were true that

Even where the amount of atmospheric ozone is normal, some ultraviolet light reaches the Earth's Surface.

What earthquake allowed researchers to develop the elastic rebound theory?

Answers

The answer is: the 1906 San Francisco earthquake.

From an examination of the displacement of the ground surface which accompanied the 1906 earthquake, Henry Fielding Reid, Professor of Geology at Johns Hopkins University, concluded that the earthquake must have involved an "elastic rebound" of previously stored elastic stress.

The elastic rebound theory is an explanation for how energy is spread during earthquakes. As rocks on opposite sides of a fault are subjected to force and shift, they accumulate energy and slowly deform until their internal strength is exceeded.

Factors that contribute to nation building are good governance, a united and inclusive society and a flourishing business community.

Great nations with great and working economies we not built in a day, but took a number of concerted efforts over time between the government and its citizen to bring such nations into limelight and a beacon for others to follow. Recommendations for building up a great nation is centred on three factors viz:

1. Good governance

2. United and inclusive society

3. Cooperative business community.

These factors listed above are crucial because it produces a society that is united, can fend for itself and harmonized in tackling challenges that cuts across all sectors such as socioeconomic development, inequality etc...

With a prospering business community, especially in instances where small and medium scale businesses are allowed to flourish and develop to their full potentials, it is seen that the income inequality is quickly bridged, thus raising the standard of living of such countries and helping to eradicate poverty. This also boosts local manufacturing and subsequently international trade with other nations thus forming meaningful ties and allies.

A government vested on good and quality educational system not only creates a sense of belonging and national unity through school curriculum, but also to develop creative and progressive minds that get to form the very fabric of the nations' financial institutes, research institutes, civil workers, engineers, future teachers, businessmen and women etc.

A society that is more equal than it was yesterday, is always one step ahead towards the goal of nation building. This is true in all aspects; a nation has to be inclusive, accommodating, diverse,...with a government with a good developmental and sustainable plan to steer the nation forward in future times to come.

Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed. c. Soil that forms on basalt bedrock will be the same as soil formed on granite bedrock because they are both igneous bedrocks. d. Soil that forms on steep slopes is thicker than soil formed on flat land because of the accumulation of sediment on slopes.

Answers

Answer: b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed.

Explanation:

Some plants require more a of particular nutrient than others and so will draw more of these nutrients from the soil whilst giving away some of the ones that they do not want. This is one of the reasons that some plants grow better in a particular area than not.

When these plants give or take away nutrients, they would be changing the type of nutrient composition of the soil and this is what makes crop rotation so effective.

The calculated density at the Earth's center makes scientists almost certain that the inner core is composed of diamond. d.

Answers

Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.

Explanation:

The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.

This is almost equal to the surface temperature of the sun which is around 5,500° C.

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.

Its music streaming and voice control technology promised to revolutionize the field. It attracted $500,000 in seed money, suggesting that it could hire the best talent and create amazing new products. But Minx quickly fell off the fast track. It spent nearly $400,000 on a Bluetooth product that sold only 28 units. In addition, a botched security update resulted in the company's having to conduct a nationwide recall of one of its smart products. Yet, other products have been successful, and the company is not facing bankruptcy. Initially, Minx offered amazing perks to attract the best and brightest talent.

To counter the long hours that the tech world notoriously demands of its workers, Minx offered relaxation areas with table tennis and foosball tables.
