Antarctica is the coldest, windiest, highest, driest, and iciest continent on Earth. It has an average elevation of over 8,000 feet and receives less than 2 inches of precipitation per year. Antarctica is surrounded by ocean, which prevents the moderating effect of water and contributes to its extremely cold temperatures, with recorded lows of -129°F. Several nations operate research stations staffed by scientists year-round to study the environment, climate, and wildlife such as penguins and whales. Tourists can visit Antarctica by ship for short trips during the summer.
Antarctica
The ship Shackleton took on his first Antarctic expedition was designed to withstand being frozen in ice, with features like a hull that could be rammed against ice and a propeller and rudder that could be hoisted out of harm's way. When ramming ice, the ship's iron-shod bows were shaped to ride up and crush ice with its weight. On the expedition, led by Robert Scott, Shackleton and his team endured slow going as they pulled sleds low on food towards the South Pole, with their sled dogs beginning to die.

Polar Bears
Polar bears live in the Arctic for half the year and on the mainland the other half, hunting berries. They are classified as mammals in the order Carnivora and resemble brown and black bears but are true carnivores that eat seals and arctic fox. Their population is as low as 10,000 in some areas due to threats like global warming melting their sea ice habitat and reducing prey like seals.
Antarctica
Antarctica is the southernmost continent, located around the South Pole. It is the coldest, driest, windiest continent and holds 90% of the world's ice and 70% of its fresh water. Antarctica is covered by a vast ice sheet that is on average 7,200 feet thick. If the ice melted, sea levels would rise 230 feet and flood many coastal cities. No permanent human residents live in Antarctica, though about 4,000 scientists reside there seasonally. Several countries have claimed ownership of parts of Antarctica but it is governed by an international treaty.
polarbear
Polar bears live in the Arctic regions of Canada, Norway, Alaska, Russia and Greenland. They have thick fur, blubber, and large paws that help them survive in extreme cold. Polar bears hunt seals and other marine life. Females give birth in dens and care for cubs for 2-3 years before they are independent. Polar bears are threatened by hunting and loss of sea ice from climate change. Conservation laws aim to protect polar bears and their habitat.

The south island kokako by Alex
A sighting of a South Island kokako, a native New Zealand forest bird previously thought to be extinct, was recently confirmed near Reefton. The kokako is a slate-grey bird with a black mask and distinctive blue wattles below its beak. It is part of an ancient group of wattlebirds and is related to the extinct huia and saddleback birds. Kokako populations have declined severely due to widespread forest destruction and predation by introduced pests like stoats, rats, and possums that raid their nests. There are north and south island subspecies of the kokako, and efforts are needed to protect the endangered populations.
Captain cook by Bella and Bridget
Captain James Cook was an English explorer and navigator who sailed the ship HMS Endeavour and made three voyages of discovery, notably mapping much of the Pacific Ocean and claiming Australia for Britain. He was sent to observe the transit of Venus in 1769 and search for the fabled southern continent of Terra Australis. Cook died in 1779 in Hawaii after a confrontation with native Hawaiians during his third voyage of exploration and mapping in the Pacific.
James cook
James Cook was a British explorer born in 1728 in Yorkshire, England who led three major expeditions to the Pacific Ocean. During his first expedition aboard the Endeavour from 1768-1771, Cook proved that New Zealand was two separate islands, mapped part of Australia's east coast, and opened the Strait between Australia and New Guinea. His second expedition from 1772-1775 saw his ships cross the Antarctic Circle for the first time. Cook's third and final expedition from 1776-1779 resulted in the discovery of the Hawaiian Islands and Christmas Island before he was killed by Hawaiian inhabitants in 1779.
Should Antarctica Be Developed?
The document discusses differing viewpoints on whether Antarctica should be developed from various interest groups including fishermen, miners, researchers, tourists, waste disposal experts, military spokespersons, World Wildlife Fund supporters, conservationists, Greenpeace, eco-campaigners, and Antarctic explorers. Each group provides arguments for their perspective, such as fishermen wanting to continue fishing for livelihoods, miners seeing resources to serve world needs, and conservation groups worrying about environmental impacts. Overall, there are mixed views both for and against development in Antarctica depending on the priorities and concerns of each interest group.
Arctic foxes
Arctic foxes have fur that changes color with the seasons and compact bodies that minimize heat loss. They live in Arctic tundra regions and prey mostly on lemmings. Arctic foxes are endangered due to hunting for their fur and competition from red foxes. Conservation efforts include laws protecting Arctic foxes and reducing greenhouse gas emissions. Arctic foxes typically mate for life and have litters of 5-9 pups that both parents help raise.

3. Two annual marathons are held in Antarctica despite it having no permanent residents. Participants face extreme cold, wind and unpredictable conditions.
4. Tourism is centered around the Antarctic Peninsula which has a milder climate and is home to penguin and seal breeding grounds. Cruise ships bring an average of
Polar lands
A post about the geographical processes of the Polar Lands and the way it works, the human interaction, the biodiversity, threats and protection.
Sea creature
This document summarizes different sea creatures like the kiwi fish and horsefish, as well as providing details about the iconic blue whale. It describes the blue whale's massive size, with hearts weighing over 700kg and tongues the size of elephants. The document also outlines the blue whale's history of overhunting leading to near extinction, before protections were established. Their lifestyle of diving deep to feed on krill and communicating over long distances with low frequency calls is also summarized.
Antarctica
Captain Cook was unable to penetrate the ice ring around Antarctica in 1773. Exploration increased in the early 19th century by sealers and whalers. In 1911, Roald Amundsen became the first person to reach the South Pole, beating Robert Scott's expedition after using dogs and eating them for food. Sir Ernest Shackleton's ship was trapped in ice in 1915. The Antarctic Treaty was established in 1959 to designate Antarctica as a scientific preserve and to ban military activity on the continent.
Antartica and artic
The document compares and contrasts the Arctic and Antarctic regions. It notes that while both are cold, dark, and remote, they differ in important ways. The Arctic is an ocean surrounded by land, while the Antarctic is land surrounded by ocean. Polar bears live only in the Arctic, while penguins live only in the Antarctic. The document then provides more details about each region, noting Antarctica is covered in thick ice and considered a desert, while the Arctic has fresh water and supports various animal life.
Last one
Australia was originally part of the supercontinent Gondwanaland before separating from Antarctica around 45 million years ago. It was home to Aboriginal Australians for over 40,000 years before being discovered by Europeans in the 18th century. The first British colony was established in Sydney Cove in 1788 with the arrival of the First Fleet which brought convicts from Britain. Australia developed into an independent nation and is now a prosperous, highly urbanized democracy known for its unique wildlife and natural landscapes.
7th Period Tundra
The document summarizes key facts about the tundra biome and its climate, plants, and animals. It notes that the tundra has very cold winter temperatures averaging around -30°F. Some common animal species found in the tundra are described in more detail, including the polar bear, Arctic fox, and snowy owl. The document also discusses how tundra plants and animals are adapted to the harsh climate and short growing seasons. In addition, it mentions some human impacts like the Alaskan oil pipeline and risks of oil spills.

Admiral richard evelyn byrd
Richard Evelyn Byrd was a pioneering American polar explorer and aviator. He was born in 1888 in Virginia and served in the US Navy until retiring in 1916 due to injury. Byrd made many expeditions to the Arctic and Antarctic regions in the 1920s-1940s, including being the first to fly over both poles. He led four Antarctic expeditions where he discovered new lands, mountain ranges, and islands while conducting extensive mapping and scientific research. Byrd wrote books about his adventures and commanded Antarctic exploration missions until his death in 1957.
Antarctica snow petrel
The Antarctic snow petrel is a small, all-white bird with black beak, eyes, and feet that is known as the most beautiful Antarctic bird. It nests in cracks in rocks in inland Antarctica, making nests from small rocks. Snow petrels feed on krill, fish, squid, and crustaceans, and sometimes scavenge dead whales. They fly low over water and high over land to avoid predators and have a gentle flight. Snow petrels live in large groups, search for mates in spring, and can live up to 20 years in the wild.
