What is an arctic plain with sub-layer of permafrost?
An arctic plain with a sub-layer of permafrost is a flat land area in the Arctic region where the ground underneath the surface layer remains permanently frozen. Permafrost is soil, sediment, or rock that stays below 0°C for at least two consecutive years, influencing the landscape and ecosystem of the area.
What is a sentence with the word permafrost?
"The permafrost makes maintaining the Alcan Highway difficult."
What is permafrost on Mars?
Permafrost is the frozen liquid or gases on Mars, that never melt. While Mars' polar ice caps do shrink and grow, there are portions of it that never melt. This is the permafrost. It is frost that never melts (ie permanent frost).
Permafrost remains throughout the summer because it is insulated by what?
Permafrost remains throughout the summer primarily because it is insulated by the layer of organic material, such as moss and vegetation, on the surface. This layer helps to trap cold air and prevent heat from penetrating deeply into the ground. Additionally, snow cover can also provide insulation by reflecting sunlight and reducing heat transfer to the permafrost below. Together, these factors help maintain the frozen state of permafrost even during warmer months.
What layers are above and below the ozone layer?
Above: the rest of the stratosphereBelow: the rest of the troposphere

How does grass covers a layer of permafrost?
Grass helps insulate permafrost by trapping snow on top of it, creating a thick layer of insulation that reduces heat transfer from the atmosphere. The grass also helps stabilize soil moisture levels, preventing rapid thawing of permafrost. Overall, the presence of grass on permafrost plays a crucial role in maintaining the frozen state of the permafrost layer.
What is a frozen layer of soil under a thin layer of topsoil called?

What term is used for the continually frozen layer of soil underneath Earth's surface in high latitudes?
Permafrost is used for the continually frozen layer of soil underneath Earth's surface in high latitudes.
Which biome has permafrost?
The tundra biome is known for having permafrost, which is a layer of frozen soil that remains frozen year-round. This layer of permafrost poses challenges for plant roots and contributes to the unique landscape of the tundra.
What is an arctic plain with sub-layer of permafrost?
An arctic plain with a sub-layer of permafrost is a flat land area in the Arctic region where the ground underneath the surface layer remains permanently frozen. Permafrost is soil, sediment, or rock that stays below 0°C for at least two consecutive years, influencing the landscape and ecosystem of the area.
What lies beneath the topsoil of the tundra?
Below the topsoil of the tundra is the permafrost layer, which consists of permanently frozen soil, rocks, and sediments. This layer acts as a barrier to water drainage and plant root growth. Beneath the permafrost layer is the unfrozen ground, which can include roots, soil, and debris.
