Solid carbon dioxide and some water ice.
food is scarce in polar regions because polar regions are mostly covered with ice so because of ice and the cold weather people cannot sell or buy things. that is why food is scarce in polar regions.
Yes, in the form of ice, mostly at the polar regions
Pluto although entirely covered by ice, is no longer considered a planet. The only planets in our solar system with polar ice caps are Earth and Mars.
Tropical regions are cooler , polar regions are colder
Two important signs are the polar ice caps in the winter and green regions in the summer.
Above the microbial level, probably not. Whether there are microorganisms, either living or in a suspended state, is a matter of ongoing debate. We won't have a definitive answer until we explore more of the planet, including its ice-covered polar regions.
We refer to the polar ice cap biome as the regions of the planet covered by ice most of the year. This includes large portions of the arctic and antarctic.
The polar ice caps are only located in polar regions.
The Polar diameter of Mars: 6,752km or 4,196 miles
The polar regions are known for their extreme cold temperatures and unique ecosystems. Many scientists conduct research in the polar regions to study climate change and its effects on the environment.
Antarctica is a continent covered -- 98% -- by an ice sheet and is about 30 degrees F colder than the Arctic, which is covered by sea ice and no land.
