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

Answers

Answer 1

Answer:

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

Explanation:

Before 1980 there was very little concern about atmospheric ozone decrease. Many plants and animals flourish in warm climates rather than in polar regions. The increase exposure to ultraviolet rays due to shift in atmospheric ozone has threatened marine life.

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.

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

Have a wonderful day and keep on learning! :D

Is a tropical rainforest vegetation similar or different to the natural vegetation

Answers

Answer:

ITS DIFFERENT

Natural vegetation comprises forests, shrubs and grasses, and is determined by climatic conditions and soil types. ... Soil formation on the hill slopes is a prerequisite for forest growth, but human practices in these areas have contributed to erosion, rather than to soil formation.

The tropical vegetation at this layer generally consists of shade-tolerant shrubs, herbs, small trees, and large woody vines which climb into the trees to capture sunlight. Only about 5% of sunlight breaches the canopy to arrive at the understory causing true understory plants to seldom grow to 3 m (10 feet).

two pieces of evidence which indicate that Paarl receives seasonal rainfall​

Answers

Explanation:

Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more than others. This paper presents the findings on research to determine whether shifts in seasonal rainfall patterns are indeed already visible in historical rainfall data in the Western Cape of South Africa. The paper aims to provide some baseline information which can stimulate further research in this field. Different analytical methods were formulated to investigate the relationships between daily rainfall indices over a set timescale. Data was collected from the South African Weather Service (SAWS) in order to accumulate 20 rainfall stations, each with at least 100 years of historical daily rainfall data. Statistical analysis, linear trend line distributions, time lag comparisons, cumulative distributions, moving average plots and autocorrelation relationships were applied to the data. The results of the analysis indicated that (1) the rainfall season undergoes fluctuations of wetter and drier years (approximately 20-year cycles), (2) the South Coast region exhibits a shift towards a longer rainfall season, and in contrast the Mediterranean region is shifting to a shorter rainfall season when linear trend lines were analysed, and (3) the moving average plots showed only isolated seasonal shifts at the boundary months.

What is population density?

The population density of a locality refers to its location within a certain geographical area. Coastal areas, dry terrain, and cold environments have higher population densities.

It is a geographical phrase used to describe population density. Because the climate is comparable to that of coastal places, the population density is high. The population density is lower in the highlands. The population density in dry lands is high. Cold lands have a high population density, whereas hot lands have a low population density.
