Antarctica is the coldest continent in the world has a total area of 13,720,000 km² which is 9% of total landmass of the world. The population of the continent is 4,490 people.
The continent surrounds the geographic South Pole and is located in the Antarctic region of the Southern Hemisphere, about wholly south of the Antarctic Circle and is bordered by the Southern Ocean.
It is one of the most no inhabitable places on earth. It is also home to a small number of plant and animal species. It is the coldest landmass on the earth and is made of permanent glaciers. About 98% of the continent has covered by ice of about 1.9 kilometers thick.
Map of Antarctica
The map of Antarctica shows oceans and regional seas around Antarctica, together with other geographical features. NSIDC scientists refer to the diverse oceans and seas when they converse sea ice level. The Antarctica Circle is one of the five most important circles or parallels of latitude that point on the maps of the Earth.
Map of Antarctica shows a dashed red line, this parallel of latitude sits at around 66.33° south of the Equator. It points the northern boundary of the area within which the sun does not set nor does it rise for one day or more each year. The duration of nonstop day or night increases southward from the Antarctic Circle, rising to six months at the South Pole.
Antarctica is the world’s southernmost continent which is bordered by the southern ocean. The continent is found generally toward the south of the Antarctic Circle and is situated unevenly around the South Pole. The southern sea which bordered the Antarctic can be additionally considered as the southern waters of the world oceans; pacific, Atlantic and Indian Ocean. The continent is mostly portrayed by ice arrangements. Being the fifth biggest continent on the planet, Antarctica is 1.3 times the dimension of Europe and covers more than 14,000,000 square kilometers.
Just 5% of the continent is made of rocky formations. Over 44% of the continent is ice racks coasting in the sea and 38% of the continent is made of ice dividers that lay on the ground, and the rest 13% is ice sheets. Antarctica is partitioned into two regions; western and eastern Antarctica by the trans-antarctic Mountains which is arranged near the neck between Ross Sea and Weddell Sea.
Around 98% of the continent is secured by Antarctic ice sheet. This is a sheet of ice that has a normal thickness of 1.6 kilometers. Over 90% of the ice of the word is situated in Antarctica, This record to over 70% of the world’s fresh water. Liquefying of this ice in Antarctica can prompt to ascend in ocean water levels by over 60 meters. The rainfall in Antarctica is low and is on a normal just 20 mm for annually. This makes the place an icy abandon.
Population of Antarctica with politics and economy
Antarctica is the slightest populated continent on the planet. There are no durable settlements in the continent. However, a few nations keep up perpetual kept an eye on research stations in the landmass. Around 1000 individuals on average amid winters and around 5000 individuals amid summer seasons lives in such research stations spread over the mainland. Mainly, Population of Antarctica is the most reduced from among the various accessible continents. Albeit numerous nations assert sway in specific territories of the continent, Antarctica has no legislature.
Antarctica is thought to be a place which is politically nonpartisan. The Antarctic Treaty marked by numerous continents in 1959 is one of the land stamp settlements that manage the exercises of the distinctive nations in Antarctica. In 1959, the arrangement was marked by 12 nations including Soviet Union, United Kingdom, Chile, Australia, Argentina and United States. Till now over 60 world nations have marked this arrangement. The Antarctic bargain puts aside the continent as a logical protect. The bargain additionally settled opportunity of logical examination and ecological insurance.
It additionally bans military movement in Antarctica. At present there are no monetary exercises occurring in Antarctica, with the exception of angling off the drift and little scale tourism which is based outside Antarctica. Antarctica likewise has little stores of coal, hydrocarbon, press metal, platinum, nickel, gold and numerous different minerals. Be that as it may, the Antarctic settlement confines misuse of such assets.
Antarctica is home to just couple of types of earthly vertebrates. There are assortments of marine creatures that live in Antarctica, which incorporates penguins, blue whales, goliath squids, orcas and fur seals. Every one of these creatures directly or indirectly depends upon the phytoplankton in the Antarctic Ocean. The solidifying temperatures, absence of daylight, dampness and poor soil nature of the continent don’t permit broad vegetation in the continent.
The vegetation which we find in the continent is for the most part bryophytes which incorporate around 100 distinct types of greeneries and 25 types of liverworts. There are just two types of flowering plans found in this continent and their development is limited to couple of weeks in summer. Other than these few types of green growth and bacteria have been discovered living in frosty Antarctic conditions.
Antarctica is the coldest continent of the Earth. The lowest temperature ever recorded on Earth was −89.2 °C on 21 July 1983 at the Soviet Vostok Station in Antarctica. For examination, this is 10.7 °C colder than subliming desiccated ice at one atmosphere of fractional pressure, however since CO2 just makes up 0.039% of air, temperatures of under −150 °C would be expected to create dry ice snow in Antarctica. Antarctica is a solidified abandon with little precipitation; the South Pole itself gets under 10 cm on average annually.
Temperatures arrive at least between −80 °C and −89.2 °C in the inside in winter and arrive at a most extreme of between 5 °C and 15 °C close to the drift in summer. Sunburn is frequently a health problem as the snow surface reflects the greater part of the bright light falling on it. Given the latitude, long stretches of consistent dimness or steady daylight make atmospheres new to individuals in a significant part of whatever remains of the world.
East Antarctica is colder than its western partner due to its higher rise. Climate fronts once in a while infiltrate far into the mainland, leaving the inside cool and dry. Regardless of the absence of precipitation over the focal part of the landmass, ice there goes on for expanded periods. Overwhelming snowfalls are regular on the beach front part of the continent, where snowstorms of up to 1.22 meters in 48 hours have been recorded.
