Polar Region PPT, Part 2: Location and Characteristics of the North and South Pole

The highest latitude position and the widest range of longitudes

Arctic sea and land locations

Determine the names of the continents and oceans represented by the letters

Antarctica is the best in the world:

1. The highest average altitude

2. The lowest temperature

3. The strongest wind and most storms

4. Fewest trees

5. The least rivers

6. The southernmost location

Polar Regions PPT, Part 3: Why the Antarctic is colder than the North Pole

①The heat capacity of the ocean is larger than that of the land. The cold and heat of the ocean change slowly, while the cold and heat of the land change drastically;

②The terrain of Antarctica is high, and the wind blows from high to low, and the wind is strong. In the Arctic Ocean area, it is high around and low in the middle, with less wind;

③Antarctica is covered with thick ice, and most of the solar radiation is reflected;

④The Arctic Ocean region is low-lying, covered with less ice, absorbs more heat from sunlight, and is affected by the Atlantic warm current.

Polar Region PPT, Part 4: Protecting the polar regions means protecting human beings themselves

March 23 is World Meteorological Day. In order to raise global awareness of the importance of changes in Arctic sea ice and Antarctic ice sheets and promote the international community's protection of polar ecosystems, the World Meteorological Organization established the "International Polar Year". In conjunction with the official launch of the International Polar Year, the World Meteorological Organization has set the theme of World Meteorological Day 2007 as "Polar Weather: Understanding Global Impacts".

Global warming has caused the polar ice to decrease, which not only affects the flora and fauna and indigenous inhabitants of the North and South Poles, but also affects the only planet on which all mankind depends for survival. Therefore, protecting the polar regions means protecting humans themselves.

Antarctic ice is also shrinking

In December 2006, international scientific researchers stationed in Antarctica said that the number of Adélie penguins inhabiting the ice gradually increased in the southern part of their habitat and gradually decreased in the northern part. This change can confirm global climate warming. This is a file photo of Adélie penguins taken in Antarctica.

"Polar Regions" PPT courseware 6 The reason why the temperature in Antarctica is much lower than that of the Arctic is that the nature of the sea and land is different: Antarctica is mainly continent and covered with ice and snow. It has strong reflection of sunlight, absorbs less heat and releases more heat, while the Arctic is mainly ocean. Releases heat slowly and altitude does not...
