Permafrost is permanently frozen ground that often underlies thermokarst terrains, which are landscapes characterized by the uneven terrain caused by the thawing of permafrost. As permafrost thaws in a thermokarst terrain, it can lead to the formation of thermokarst features such as depressions, ponds, and landslides due to the melting ice and collapsing ground.

What land forms occur in the arctic tundra?
In the arctic tundra, you can find land forms such as permafrost, which is permanently frozen soil, and polygonal ground, characterized by patterned ground with raised centers and sunken troughs. Other common land forms include pingos, which are dome-shaped mounds formed by ice lenses, and thermokarst features like lakes and ponds resulting from melting permafrost.
What happpens to the ground in the tundra during the summer?
In the tundra during summer, the permafrost thaws partially, creating a layer of waterlogged soil on top. This layer can be several centimeters thick, making the ground spongy and unstable. It also increases the potential for erosion and the formation of thermokarst features such as ponds and hummocks.

What are the landforms in a tundra?
Some landforms found in tundras include permafrost, which is frozen soil that remains frozen year-round, creating a unique landscape. Other landforms can include low-lying areas called thermokarst, created by melting permafrost, as well as glacial features like moraines and cirques. Overall, tundras have a relatively flat terrain with few trees due to the harsh climate conditions.
What operates primarily in areas of permafrost?
Permafrost primarily hosts operations of oil and gas drilling, mining, construction, and research activities related to studying climate change and permafrost dynamics. These areas are also home to certain indigenous communities who have adapted their lifestyles to living in permafrost regions.
What percentage of Canada's area is permafrost?
About 50%. See 'related links' for more information'.
