If you are looking for Class 5 SST The Frigid Zone Question Answer then your search ends here.
Short Answer Questions:
What is the latitudinal location of the frigid zones?
The frigid zones are located beyond 66.5° latitudes, both in the northern and southern hemispheres.
Why is the frigid zone so cold?
The cold region is extremely cold due to its polar position, receiving oblique rays of the Sun and being away from the direct rays of the Sun for certain periods during the Earth’s revolution.
How long can nights be in the tundra region?
In the tundra region there can be nights continuously for six months during the winter season.
Why is it impossible to grow crops in the frigid zone?
Farming is impossible in the cold region due to dry and snowy plains, poor soil quality and extremely cold temperatures.
What are harpoons?
Harpoons are pointed spears, traditionally made of animal bones or stones, with leather ropes attached. They were used to hunt large seals and walruses in cold regions.
Long Answer Questions:
Describe location and distribution of the frigid zone in both hemispheres.
The cold zone lies beyond 66.5° latitude, divided into the northern cold zone (from the Arctic Circle to the North Pole) and the southern cold zone (from the Antarctic Circle to the South Pole). Areas like Canada, Alaska, Scandinavia, Greenland, Iceland and Siberia fall in the cold zone.
How can you say that the climate of the frigid zone is harsh and cold?
The cold region experiences extremely cold temperatures, with average annual temperatures as low as -50°C. It experiences six months of continuous darkness and six months of continuous daylight, with frequent blizzards, minimal rainfall and heavy snowfall. The presence of ice sheets, ice shelves, and frozen subsoil contribute to the harsh climate.
What are the unique spectacles observed in the polar regions?
Unique spectacles in the polar regions include the aurora (Aurora Borealis in the Arctic and Aurora Australis in the Antarctic) and diamond dust, a ground-level cloud composed of tiny ice crystals.
Describe diversity of vegetation in polar regions.
The tundra regions have limited vegetation due to the cold climate, poor soil quality, and permafrost. Vegetation includes shrubs, sedges, mosses, lichens, grasses, and small flowering plants. Antarctica, being too cold and dry, has areas with rocky soil that support minimal plant life.
How have animals adapted to the cold harsh climates of the frigid zone?
Animals in the frigid zone, such as polar bears, reindeer, foxes, wolves, and birds, have adapted to the harsh climate. They have features like white fur for camouflage, migratory behaviors, hibernation, and specialized swimming abilities.
Describe the way of life of the Inuit people.
The Inuit people, living in the frigid zone, traditionally dwell in snow-houses (igloos) made from large blocks of ice. They are nomadic, using tents (toupigs) in summers. Their diet consists of reindeer, seals, walruses, and fish, providing essential fats for warmth. Clothing is made from animal skins, and sledges drawn by reindeers or huskies are used for transportation. The Inuit have also adapted to modern living in recent times.
HOTS Questions:
Why does the Sun not set in polar regions in summer and does not rise in winter?
The tilt of the Earth at an angle of 23.5° causes the polar regions to be completely away from the rays of the Sun at certain times of the year during Earth’s revolution. This results in six months of continuous daylight in summer and six months of continuous darkness in winter.
Why is the tundra region considered a carbon dioxide sink of the world?
The tundra region acts as a carbon dioxide sink because of its permafrost, which stores vast amounts of organic carbon. When this permafrost thaws, it releases carbon dioxide and methane, contributing to greenhouse gas emissions.
How do people in nations located in polar regions live as they face ‘half yearly’ days and nights?
People in polar regions, such as the Inuit, have adapted to the ‘half yearly’ days and nights by utilizing traditional housing, clothing, and transportation suited for extreme conditions. They rely on hunting, fishing, and herding as major occupations, with some adopting modern technologies and lifestyles in recent times.
