permafrost
yes it can. Tundra is a name given to the permanently frozen ground in the north of Canada and Russia. Tundra NEVER thaws even in the summer.
The top layer of soil in the tundra that thaws in the summer is called the "active layer." This layer thaws and refreezes seasonally, influencing plant growth and nutrient availability. It is important for various ecological processes in tundra ecosystems.
The top layer of soil in the tundra that thaws in the summer is called the active layer. This layer is seasonally thawed and frozen, and it plays a crucial role in supporting vegetation growth in the tundra ecosystem.
The top layer of soil in the tundra that thaws in the summer is called the active layer. This layer of soil experiences seasonal freezing and thawing, with vegetation able to grow during the short summer months when the active layer thaws.
A frozen ground that never thaws is call firnward. Also, permafrost.
Areas where the ground never thaws (a layer near the surface might thaw but deeper down, the ground is frozen all year and has been for thousands of years).
The top layer of soil thaws :D
The greenhouse gas released as the tundra thaws is primarily methane. As the permafrost melts, organic material previously frozen in the soil decomposes and releases methane gas. Methane is a potent greenhouse gas that contributes to global warming.
During summer, the ground in tundra thaws and becomes soggy and wet. The cycle of freezing and thawing, crushes plant roots. This, in addition to cold temperatures, high winds, and short growing season, limit plant heights.
The "Active layer" is the few inches of permafrost that thaw in the summer.

In the tundra during summer, the ground thaws and becomes waterlogged due to melting permafrost. This creates wet and marshy conditions, allowing plant growth and supporting a variety of wildlife. The top layer of soil may also become nutrient-rich, promoting the growth of vegetation.
