The Earth has two poles, a north pole and a south pole. At both poles, the temperature drops to near freezing. Despite these conditions, their beauty is unparalleled. Discover everything about the polar climate and landscape in this post: what it's like, its characteristics, flora, fauna, and much more.
What is the polar landscape or climate?
The polar landscape or climate is that found in areas of permanent cold. In these regions, winter can last more than six months, and although summer exists between the seasons , it is not the same as in other parts of the world.
The average temperature ranges from minus 25 °C and the records of the lowest values have been minus 40 °C. The exceptional climate of the poles is not really because of its low temperatures, rather it has to do with the absence of a true summer season, to balance the scale.
How is the polar landscape?
All ecosystems have aspects that differentiate them from each other and the most outstanding characteristics of the polar landscape or climate are mentioned below.
- Low temperatures: In these cold regions, the Sun has a very low affectation with its rays. This feature is due to the tilt of the Earth, this particularity causes temperatures at the poles to be below 0 °C.
- Little precipitation: As there is no presence of humidity in these areas, in addition to the minimum temperatures, the rains do not occur very frequently. What they can observe is that small portions of snow fall and cover the surface.
- Strong winds: The wind that blows at the poles can reach up to 100 kilometers per hour. These high and permanent speeds are due to the low temperature and the pressures exerted by the atmosphere.
- Duration of day and night: One of the most outstanding characteristics of these polar landscape zones is that the days have very significant differences. For example, in the summer season the sunlight can be observed 24 hours a day. While, during the winter, it will be dark all day.
- Drift ice surfaces: Part of the polar landscape, it is full of large blocks of ice, which protrude from the surface of the seas and oceans and circulate with the current, aimlessly. These pieces of ice are fragments that have been released from the glaciers.
- Plants and animals: The diversity of animals and plants in the regions of polar climate, are very scarce. This condition is due to the low temperatures that make the environment not conducive to the survival of many species.
- Non-ideal surfaces for sowing: The surface part of the ground of the poles is covered by ice for much of the year. This condition makes them unsuitable for developing crops that allow permanent communities to be established.
- Dry weather: As a result of the few rains, there is no possibility of humidity, which facilitates the development and multiplication of other species, less adapted to extreme weather.
Types of polar climate
According to the pole of the Earth where they are, they will have an Arctic and Antarctic polar landscape. Traveling in the direction of the northern hemisphere, they will be in the Arctic. While Antarctica is located in the southern hemisphere.
- Arctic polar climate: In the winter season, this region of the planet can have temperatures below minus 50 °C. It has two categories which are:
- Continental Arctic, extremely dry climate and far from coastal areas.
- Maritime Arctic, very close to the Seas and oceans and the summer season is quite warm, with an average of 8 °C.
- Antarctic Polar: The lowest temperatures on the entire planet are found in this region. And it is divided into:
- Portugal.
- Antarctic Peninsular.
- Maritime.
- Tundra Polar Climate: Geographically this region can be located in Norway, Russia and Siberia. It is characterized by having temperatures that can range from 0 °C to 15 °C, temperatures that occur during the least cold months.
- Cap fleece: El ice cap polar climate it is typical of the Greenland Islands and throughout the year, temperatures are below freezing.
Fauna, flora and much more
These polar landscape regions are a tough nut to crack for many animals and plants. In addition to the hard tests that they put on the human beings who decide to settle in these inhospitable places.
The conditions for farming are not ideal, hunting and fishing also have their risks. However, the animals and the human species manage to survive.
- Flora: Due to the intensity of the winds, many species have very little size and this allows them not to feel the impact so drastically. Only a few plant varieties can be found in the tundra.
The characteristic species of these regions are:
- Algae
- lichens.
- Moss.
- Low-growing bushes that spread like a carpet on the ground.
- Fauna: La polar climate fauna, faced with the need to adapt to the environment, has changed the color of its fur, this is white to repel the cold. They accumulate a large amount of fat under their skin to withstand extreme weather or have migratory habits.
In each hemisphere of the planet, the specimens of the fauna are characteristic. But the most common are:
- Wolves.
- Bears.
- Seals
- sea lions
- Penguin.
- Whales
- Moose.
- Communities: The people who decided to settle in these remote regions had to adapt their clothing to withstand the low temperatures. In addition to changing eating habits, their way of living, relating to other people and the environment.
The most relevant settlements of people in the polar landscape are found in Russia, Greenland, Alaska, among others. Their diet is based on the consumption of seal meat, whale meat and different varieties of fish.
- Displacement: The means of transport used is the sled pulled by dogs. Although it is still a widely used means of transport, for long-distance travel, they use snowmobiles and other modified vehicles.
The kayak and boats use it for water transport and fishing.
- Economy and culture: The industrialized economic activity of the region consists of gold mining, coal mining, oil extraction and iron ore. But locally, the economy revolves around the sale of hunting skins, when the seasons are open.
Cultural activities revolve around dances and songs of gratitude for good fishing and hunting.
