General Awareness: Some amazing facts about Antarctica , a study material on Antarctica , with images

Do you know:   One area of the world that needs our help the most is Antarctica, with its ice melts affecting the entire world's climate.


Ninety-nine percent of Antarctica is covered by ice.

Antarctica is the southernmost continent on Earth and is located almost entirely within the Antarctic Circle. Here are some key points of information about Antarctica:

Geography: Antarctica is the fifth-largest continent, covering an area of approximately 14 million square kilometers (5.4 million square miles). It is largely covered by ice, with an average thickness of about 2,160 meters (7,087 feet). The highest point is Mount Vinson, reaching 4,892 meters (16,050 feet) above sea level.

Climate: Antarctica is the coldest place on Earth. The average temperature in winter ranges from -40°C (-40°F) to -60°C (-76°F), while in summer, it can reach -15°C (5°F) along the coast. The continent is characterized by strong winds and low precipitation, primarily in the form of snowfall.

Scientific Research: Antarctica is an important destination for scientific research. Several countries have research stations and field camps scattered across the continent, where scientists study various disciplines such as climate change, glaciology, geology, astronomy, and marine biology. The Antarctic Treaty System, signed by many nations, governs the peaceful and cooperative use of the continent for scientific purposes.

Wildlife: Despite the harsh conditions, Antarctica is home to diverse wildlife. Penguins, seals, whales, and seabirds are among the most iconic species found in the Antarctic region. The Southern Ocean surrounding Antarctica supports abundant marine life, including krill, which forms the basis of the Antarctic food chain.

Tourism: Antarctica attracts adventurous travelers who seek to explore its pristine wilderness. However, due to its fragile ecosystem, tourism is regulated through guidelines and permits to minimize environmental impact. Visitors can experience stunning icebergs, vast ice sheets, and unique wildlife through guided cruises and land excursions.

Political Status: Antarctica is governed by the Antarctic Treaty System, which came into effect in 1961. The treaty prohibits military activity, mineral mining, and nuclear testing on the continent. It also promotes scientific cooperation, environmental protection, and the freedom of scientific research.

Environmental Concerns: Antarctica is highly vulnerable to climate change. The melting of ice sheets and glaciers contributes to rising sea levels, which can have global implications. Efforts are underway to understand and mitigate the impacts of climate change on Antarctica and the world.


On average, Antarctica is the windiest continent. Winds in some places of the continent can reach 200 mph (320 km/h).



The Dry Valleys of Antarctica are a unique and extreme polar desert region located in the McMurdo Dry Valleys, a valley system in Victoria Land, East Antarctica. Here are some key details about the Dry Valleys:
The Dry Valleys of Antarctica are the driest place on Earth, with low humidity and almost no snow or ice cover.
Geographic Features: The Dry Valleys encompass a series of valleys, including Taylor Valley, Wright Valley, and Victoria Valley, among others. These valleys are characterized by their extremely dry and barren nature, devoid of any visible surface ice or snow.

Lack of Precipitation: The Dry Valleys are considered the driest places on Earth, with an annual precipitation of less than 10 centimeters (4 inches) of snowfall equivalent. The region's unique topography and katabatic winds (downslope winds) effectively prevent the accumulation of snow and ice.

Absence of Glaciers: Unlike other parts of Antarctica, the Dry Valleys have no glaciers. The combination of low precipitation, high evaporation rates, and wind scouring prevents the formation and maintenance of glaciers in this region.


Ice Sheets and Glaciers: Antarctica is covered by a massive ice sheet, known as the Antarctic Ice Sheet, which contains about 90% of the world's freshwater. The ice sheet has an average thickness of around 2,160 meters (7,087 feet) and holds an estimated 26.5 million cubic kilometers (6.36 million cubic miles) of ice. Glaciers also flow from the ice sheet towards the coast, carrying freshwater in the form of ice.


The average thickness of Antarctic ice is about 1 mile (1.6 kilometers).



Antarctica is home to Mount Erebus, the southernmost active volcano on the planet and home to Earth's only long-lived lava lakes.
Who was the first human to reach the south pole? 
Norwegian explorer Roald Amundsen was the first human to reach the South Pole. He beat out English explorer Robert Falcon Scott by arriving on Dec. 14, 1911, and planting the Norwegian flag.

British explorer and meteorologist Felicity Aston was the first person ever to ski across Antarctica powered only by human muscle. She traveled 1,084 miles (1,744 kilometers) in 59 days between late 2011 and early 2012.
