In 1–2 sentences, explain what biome comprises most of Antarctica and why the continent is described as being part of this biome.
In one to two sentences, describe characteristics of a high-pressure system.
The biome that comprises most of Antarctica is the polar desert biome, characterized by extreme cold temperatures, strong winds, and very little precipitation, making Antarctica part of this biome.
A high-pressure system is characterized by descending air that creates a stable and dry weather pattern, with clear skies, low humidity, and light winds.
Explain for 6th grader.
Antarctica is mostly made up of a place called a polar desert where it's very cold, very windy, and hardly ever rains or snows. That's why we say it's part of the polar desert biome.
A high-pressure system is when the air in the atmosphere above us sinks down and creates stable and dry weather. It means there are clear skies, not much humidity (moisture in the air), and not a lot of wind.
Most of Antarctica is comprised of the polar desert biome, as it is characterized by long, cold winters, very low precipitation, and strong winds, making it considered as part of this biome.
A high-pressure system is typically characterized by descending air, resulting in stable atmospheric conditions, clear skies, and often fair weather.
