At the North Pole, in winter, there is a sea covered with ice. But in the summer, some of that ice becomes water. This water will then absorb the sun’s rays. … The sun’s rays do not penetrate the ice cap.
Why is it hotter in the South than in the North?
The northern hemisphere is tilted towards the Sun during the summer. It is therefore warmer in summer, because the rays reach our regions more perpendicularly than in winter. … During our winter, the southern hemisphere is tilted towards the Sun. It is then summer in the southern hemisphere.
Why is it hotter at the equator? At the equator, the sun’s rays arrive vertically and are therefore very powerful. The closer you get to the poles, the more oblique the sun’s rays. The path they will have to travel through the atmosphere will therefore be wider (a straight line is always the shortest path), which will weaken them.
Why is it hot? If it is hotter in summer, it is because of the axis of rotation of the Earth. The Earth turns on itself, and at the same time it turns around the sun, for about a year. And when it turns on itself, it turns by bending. It is the axis of rotation of the earth.
Why do we say Antarctica?
The name “Antarctica” comes from the Greek ἀνταρκτικός / antarktikós, which means “facing the Arctic”.
What is the difference between the North Pole and the South Pole? The South Pole is located at 2,835 meters above sea level. The Arctic is a sea, the Arctic Ocean, a kind of polar Mediterranean. The North Pole rests on a sea covered with a changing layer of 1 to 4 meters of ice with depths of 3,100 to 5,000 meters.
Which pole has the earth? The geographic North Pole of Earth, or simply the North Pole, is the northernmost point on planet Earth.
How not to confuse the Arctic and the Antarctic? In order not to confuse the Arctic and Antarctica, we refer to the number of letters in the word Antarctica: it contains more letters than Arctic, so it is heavy (consider the weight of the continent), and it “flows” and is located in the southern hemisphere.
What is the country where the sun does not set?
When Liisa presents her country, she likes to say that she lives in the same country as Santa Claus. A country where the sun never sets in summer and where winter looks like a succession of long dark nights.
What is the country where it is always daylight? The midnight sun, or polar day, is a natural phenomenon that occurs in summer south of the Antarctic Circle and north of the Arctic Circle, including northern Norway.
What are the countries where it never gets dark? In Reykjavik, Iceland, it’s daylight for over twenty-one hours at a time. Even at night it is not really dark.
Why in Canada is it warmer in summer than winter?
A beam of light that strikes the surface of the Earth in Canada in winter therefore transmits less energy to the Earth than in summer. … It is therefore warmer in summer, because the rays reach our regions more perpendicularly than in winter.
Where is the warmest in Canada in winter? Osoyoos Lake is considered the warmest in Canada (c.
Why is it hotter in France than in Canada? The North Atlantic is home to two remarkable ocean currents, one coming from the Arctic, the other from the Caribbean Sea. These currents are themselves due to the winds which cross the ocean, by exerting a mechanical energy on the surface of the sea, and largely affect the climate.
Why is it so hot in Canada? Extreme temperatures in Canada: what is the “thermal dome” and why does it occur? … This phenomenon occurs under the influence of a “thermal dome”, the scientists explain. High atmospheric pressure traps warm air and pushes it towards the ground.
Is it snowing at the North Pole?
Both poles are covered in ice and snow, but it would be wrong to believe that the Arctic and Antarctica are identical. The North Pole is located in the middle of the Arctic Ocean, while the South Pole is on a continent, Antarctica.
Is it snowing in Antarctica? True snowfall is quite rare. Indeed, it falls on average only 5 cm of rain per year. Antarctica is technically a desert and one of the dries. The reason for this is simply that cold air does not contain much water.
Is it snowing at the South Pole? The climate of the South Pole is desert and the place receives almost no precipitation. The air humidity is almost zero. However, strong winds can carry snow over the entire region and its accumulation reaches about 20 cm per year.
What are the climatic conditions at the North Pole? The North Pole is significantly hotter than the South Pole because it is at sea level in the middle of an ocean that acts as a heat reservoir, rather than above the land. In winter (January), the temperature at the North Pole can vary from 43€ to 26°C, for an average of 34°C.
What is the temperature at sea level?
The water temperature of the North Sea is currently warming at a rate between 0.023°C per year in the northern part and 0.053°C per year in the central and southern part.
What is the temperature at the bottom of the ocean? The further down you go into the ocean, the more the water temperature drops, dropping to 2°C from 1000 m deep and to the greatest depth, whatever the region or the season. In 75% of ocean waters, the water temperature varies between 0° and 6°C.
What is the warmest sea? The Indian Ocean is the warmest ocean on the planet. The water temperature at its surface can exceed 30°C (86°F) in some places, but its average surface temperature is 22°C (71.6°F).
What are the two elements that cause the cold at the North Pole?
The Arctic is the smallest ocean in the world, located at the North Pole. This is frozen sea water, called “pack ice”. Polar cold: at the poles, the speed of the wind is added to the very low temperatures to accentuate the cold. At the North Pole, the sun does not rise from September to March, it is a polar night.
Why is it cold in Greenland? The cold in high altitude regions is mainly explained by a very low angle of incidence of the sun’s rays (46°54′ at the polar circle and 23°26′ at the pole), therefore the earth’s surface receives very little energy . and the heat received is therefore very low.
Why is it so cold at the North Pole? In concrete terms, between the two tropics, the sun’s rays hit the earth’s surface perpendicularly, so it is very hot. At the poles, the rays are more oblique, so it is colder.
What characterizes the polar regions? The polar regions are characterized by the polar climate which is a cold climate all year round. Temperatures rarely exceed -30°C in summer in Antarctica, however they can drop to -90°C in winter. Most often they are stationary around -50°C.
What’s the coldest thing in the world?
A magneto-optical trap like this can cool atoms to just a few microcelvines, or -273 degrees Celsius. This technique was developed in the 1980s and the scientists who contributed to it won the Nobel Prize in Physics in 1997 for their discovery.
What is the hottest element in the world? Zirconium comes from another mineral, zircon. However, zircon only becomes zirconia if it is subjected to a temperature of at least 2,370 degrees.
What is the coldest liquid? Record: liquid water at -42.55°C.
What is the coldest material in the world? Physicists have indeed embarked on a cold race to test their theories on matter: in 2011, the Wolf Band Ketterle team, winner of the 2001 Nobel Prize, from the Massachusetts Institute of Technology succeeded in cooling rubidium atoms to at 5 cents. billionth year above …
What is the coldest hemisphere?
The new cold record in the northern hemisphere is – 69.6°C – Le Point.
What is the coldest country in the world? What is the lowest temperature on the Earth’s surface? -98°C according to recent satellite measurements. This extreme temperature was recorded over the Mid-Antarctic Ice Sheet during a long polar winter.
Why is Antarctica colder than the Arctic? This difference is explained by the way in which the two poles are constituted. To the south, the ice cap is several kilometers thick. The sun’s rays can therefore not penetrate it and the rocky ground under the “White Continent” retains its extreme cold almost all year round.
What is the coldest pole?
The North Pole being the northernmost place, it is colder there.
Which country is the coldest? Verkhoyansk and Ojmjakon are the coldest places on earth, and although the average annual temperature is lower in Russia than in Canada, there are places in Russia that are colder than Canada, and vice versa.
What is the country where it is always dark?
The countries where it is dark for a very long time are countries close to the pole such as Greenland, Norway, Iceland, Finland and Sweden. This is due to the rotation of the Earth and its tilt. Because the Earth is tilted at 23.45 degrees, the North Pole only has sunlight 6 months out of the year.
Where is it always dark? Tromsø is a peaceful little town located in northern Norway. Inhabited by just over 74,500 inhabitants, the winter is harsh, very harsh. So to speak, it’s dark all the time. If in France, it is only an impression, over there, the polar nights are a reality.
Is it dark in Alaska? In fact, even in far northern Alaska, night is never complete, as the sun always reflects below the horizon. The moon is also reflected in the snow and ice, and the northern aurora paints the sky with its colorful beams.
Why is it hot on Earth?
You should know, first of all, that our planet is surrounded by essential protection: the atmosphere. … This gas layer acts as a protective blanket. It filters some of the sun’s rays, but above all, it keeps us warm!
Why is the sun hotter than before? So the Sun will get hotter and brighter and brighter. After all the hydrogen is used up, it will continue to burn helium in the core to complete its combustion. The latter will then have reached such high temperatures (100 million degrees) that it will push back the outer layers of the universe.
Why is it hot at night in summer? Large buildings in urban areas store heat during the day and re-radiate it at night. If there are many buildings, not only are their cumulative effects, but heat is also trapped between the walls. The temperature therefore rises incontestably, by convection.
Is it hot in space? In the Universe the temperature reaches -272°C. The lowest theoretically possible temperature is absolute zero at -273.15°C. At this temperature, the atoms no longer move! Even in space, far from any star, one cannot descend so low.
