The geographical names of the polar regions, the climate of the polar regions, the topography and th

Temperatures rarely rise above 0 in most parts of the Antarctic and Arctic. The frozen beauty there is made up of different types of ice. When the snow falls onto land, it stacks up, and the snow particles form glacial ice under the squeezing.

Huge glacier ice forms ice caps that cover much of Antarctica and Greenland.

These ice sheets, often more than a kilometer thick, store most of the planet's freshwater resources. In the extreme cold zones of the polar regions, the surface of the ocean freezes, which is known as sea ice. Most of the waters, as well as the coast of Antarctica, are covered with sea ice.

However, the Arctic Ocean and Antarctica are not completely covered in snow and ice. In summer, many areas outside the pole are ice-free, and the land is covered with numerous tundra vegetation with very short growth periods.

The north and south ends of the earth are the coldest places on the planet. When the oceans freeze, it also means the arrival of the coldest season in the polar regions.

Every year in April, the sea begins to slowly cover the ice and snow, and when the sea surface is finally completely frozen into a piece, the terrible winter in Antarctica really comes.

The cold climate of Antarctica and the Arctic Ocean, as well as the ocean and land that surrounds them. In the Northern Hemisphere, the northern boundary where trees grow can be used as the southern boundary of the polar climate. In most of the polar climate zones of the Northern Hemisphere, permafrost waters are surrounded by continents.

In winter, there is no solar radiation in the polar night. The sun does not set all day during the polar day in the summer half of the year, but the reflectivity of ice and snow is strong. The heat obtained from solar radiation is not enough to melt the snow and ice, so the summer temperature is still low.

It can be summed up in four words: severe cold all year round.

The polar ice sheet climate occurs in Greenland, the Antarctic continent and several islands in the Arctic Ocean. It is the source of the ice ocean air mass and the Antarctic air mass, which is severe throughout the year, with the average temperature of each month below 0, and the lowest annual average temperature in the world. The average annual temperature in the Arctic is about 1 to -35 in the Antarctic continent.

There are long periods of polar day and polar night in a year. The annual precipitation is less than 250mm, and all of it is dry snow, which does not melt, and accumulates for a long time to form a very thick ice sheet. Strong winds, cold sleet, and poor visibility all year round.

Polar climate, also known as boreal climate, includes two types: icefield climate and tundra climate.

1. Ice sheet climate DAO is distributed in Antarctica.

On the mainland and some of the islands in the Arctic Ocean, it is cold all year round, and the ground is covered with a thick layer of ice and snow.

2. The tundra climate is distributed in the northern edge of the Eurasian continent and the North American continent, with no summer in winter, and mosses, lichens and other plants grow on the ground.

Land and sea location in the polar regions: The central part of the Arctic region is dominated by the Arctic Ocean, and the surrounding area is dominated by the northern margins of the Eurasian and North American continents, including some islands. The central part of the Antarctic region is dominated by the Antarctic continent, surrounded by the Pacific Ocean, the Atlantic Ocean and the Indian Ocean.

Topography of the Antarctic region: The Antarctic continent is covered with a thick layer of ice, and the main terrain consists of mountains, plateaus, and basins.

The topography of the Arctic region: The land topography of the Eurasian continent and the North American continent is dominant, and consists of plains, mountains and plateaus.

The so-called polar region refers to the region within the polar circle. Including the Antarctic region and the Arctic region.

Antarctica: A vast area south of the Antarctic Circle at 66°34 (Antarctic Circle), with Antarctica as the center, surrounded by three oceans: the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean.

Arctic region: refers to the vast area north of 66°34 north latitude (Arctic Circle), with the Arctic Ocean as the center, surrounded by three continents: Asia, Europe, and North America.

Arctic region: Centered on the Arctic Ocean, it is bordered by three continents: Asia, Europe, and North America. Antarctica: Antarctica is the center, surrounded by three oceans: the Pacific Ocean, the Atlantic Ocean, and the Indian Ocean.

1. It refers to the far and far place of the earth. 2. The South Pole and the North Pole of the earth are dismantled. One of the two ends of the earth's axis.
