Question

Describe Antarctica's qualities and explain why this unique continent would attract scientific study.

Answer 1

Answer:

Hey mate..

Here is ur answer...

Antarctica is a remarkable continent – remote, hostile and uninhabited. This frozen continent is key to understanding how our world works, and our impact upon it. Antarctica is important for science because of its profound effect on the Earth’s climate and ocean systems. Locked in its four kilometre-thick ice sheet is a unique record of what our planet’s climate was like over the past one million years.

Antarctic science has also revealed much about the impact of human activity on the natural world. The discovery in 1985 by scientists at British Antarctic Survey (BAS) of the hole in the ozone layer above Antarctica revealed the damage done to the Earth’s atmosphere by man-made chemicals.

Its frozen wastes have fired the public imagination for generations, and around 30,000 tourists now visit the Antarctic each year to experience what life is like in the Earth’s last great wilderness. However, Antarctica is fragile and increasingly vulnerable.

As the UK’s national Antarctic operator, BAS has been responsible for most of the UK’s scientific research in Antarctica for the past 60 years. BAS now operates five research stations, two Royal Research Ships and five aircraft in and around Antarctica.

It fulfils this stewardship role by working to the highest environmental standards in all its operations and by playing a leading role in the Antarctic Treaty – the world’s most successful international agreement. The UK was the first nation to sign the Treaty’s Protocol on Environmental Protection, which commits Treaty parties to the environmental protection of Antarctica – a continent that few of us will ever visit, but on whose continued health we all depend.

Answer 2

Antarctica's qualities

Explanation:

• Antarctica is a unique continent which does not have a native populace. There are no nations in Antarctica,though 7 countries claim different parts of it: Australia, New Zealand, Norway, France, Chile, Argentina, and the UK
• The Antarctic encompasses within Antarctic Convergence island territories(South Orkney Islands, South Georgia, the South Sandwich Islands, McDonald and Heard islands, Scott Island, the Balleny Islands, Bouvet Island, and Peter I Island). The region is covered by the Antarctic Ice Sheet. It is the Earth's largest single piece of ice. When ice and snow are most extreme, this ice sheet stretches across the continent.
• Antarctica has several mountain summits, comprising the Transantarctic Mountains that divide the continent into western and eastern regions. Antarctica has intensely cold and dry climate. Winter temperatures range from -10°C-30°C. During summer, the temperatures hover around 0°C- 9°C .
• The Antarctic will appear without ice as a vast peninsula and archipelago with the mountainous islands, referred to as Lesser Antarctica (younger, volcanic and sedimentary rock)  and a single large landmass  referred to as the Greater Antarctic (composed of older, metamorphic and igneous  rocks). There are various geologies in these regions.
• Mosses, terrestrial algae, and lichens are amongst the few species of vegetation which  grow in Antarctica. This vegetation grows in the coastal and northern regions of Antarctica, whereas the interior has  very little vegetation.

This Unique continent attracts scientific study because

• In global climate processes, the Antarctic region plays a crucial role. It is a vital part of the heat balance of the Earth The heat energy/energy balance is the relation between the quantity of solar heat absorbed by the atmosphere of the Earth and the quantity of  heat reflected back into space.
• The reflectivity of the Earth's surface reduces as global ice cover (glaciers and ice sheets) reduces. This allows the Earth's atmosphere to absorb more incoming solar radiation, resulting in the latest climate change activity causing an unequal heat balance related to global warming.
• Thus, The Antarctic has become a symbol of climate change. In this environmentally sensitive region, scientists and policy makers are working on reforms to push for conservation and the sustainable use of its scientific resources.
