Permafrost is a type of ground that remains completely frozen for at least two years straight. It is commonly found in polar and high-altitude regions. Permafrost is made up of a combination of soil, rocks, and sand, which are held together by ice. Let's examine each statement in detail:
Statement 1: Permafrost is any ground that remains completely frozen for at least two years straight.
This statement is correct. Permafrost refers to any ground that remains frozen for a prolonged period, typically two or more consecutive years. It is characterized by the presence of ice in the ground, which prevents the soil and other materials from thawing.
Permafrost is primarily found in regions with cold climates, such as the Arctic and subarctic regions. It forms when the temperature remains below freezing point for extended periods, allowing the ground to freeze. It acts as a natural freezer, preserving organic matter and ancient remains, including plants, animals, and even human artifacts.
Statement 2: Permafrost is made of a combination of soil, rocks, and sand that are held together by ice.
This statement is also correct. Permafrost consists of various materials, including soil, rocks, sand, and gravel. These materials are bound together by ice, creating a solid and frozen ground layer. The amount of ice content in permafrost can vary, ranging from a few percent to more than 90% of the total volume.
The ice in permafrost acts as a cementing agent, holding the soil particles and other materials together. It forms a continuous matrix within the ground, creating a rigid structure. The ice also affects the mechanical properties of permafrost, making it more resistant to deformation and movement.
In conclusion, both statements regarding permafrost are correct. Permafrost is any ground that remains frozen for at least two years straight and is composed of a combination of soil, rocks, and sand held together by ice.

Scientists recently revived a worm that was frozen 46,000 years ago below the surface in the Siberian permafrost.
About Permafrost:
- Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight.
- Global Distribution:
- These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.
- Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath.
- Composition:
- Permafrost is made of a combination of soil, rocks and sand that are held together by ice. The soil and ice in permafrost stay frozen all year long.
- Near the surface, permafrost soils also contain large quantities of organic carbon—a material leftover from dead plants that couldn’t decompose, or rot away, due to the cold.
- Lower permafrost layers contain soils made mostly of minerals.
- A layer of soil on top of permafrost does not stay frozen all year. This layer, called the active layer, thaws during the warm summer months and freezes again in the fall.
Hence both statements are correct.
