Answer:

Positive feedback

Explanation:

Positive feedback climate is usually defined as the process where there occur changes in the region where the lighter colored surfaces such as the region of glaciers, ice caps are replaced by the dark-colored surfaces, and this results in the decreasing of the albedo (light-reflecting property) and also increase in earth's surface temperature. This type of feedback is also known as the ice-albedo feedback.

High rate of heating results in the decreasing amount of glaciers and ice-caps, thereby leading to the global warming effect.

Thus, the above-given condition is an example of positive feedback.

Look at the data above. Provide an explanation for Europe's projected population decrease by the year 2050.
irakobra [83]

<u>Answer:</u>

<em>Europe is a continent that for some time now has had a problem with its population.</em>

<u>Explanation:</u>

The reason for it is that <em>Europe's birthrates</em> have been very low, not enough even for just maintaining the same number of population, <em>as the birthrates are below 2 children per wife all countries apart from three. </em>

The only three countries where the average is more than 2 children per women are Ireland, Albania, and Kosovo, all of which are small countries with small populations.

<em>Also the life expectancy in Europe is relatively high, so the older population is constantly increasing, thus resulting in an aging population. </em>

Of course the elderly people will eventually pass away, and with the <em>smaller and smaller number of youngsters and very low birthrates the continent will constantly lose more and more population.</em>
