Answer: D. It can melt to a depth of a few meters in summer, then refreeze in winter.
Explanation:
Permafrost is ground which remains frozen for two or more years. Permafrost consists of soil, rock and sand fused together by ice. Mostly found in areas in high altitude, the Arctic, Antarctica, it is common in periglacial environments where temperatures are below freezing
.
The topmost layer of permafrost can melt in summer and refreeze in winter. This thawing and refreezing produces a ground pattern called columnar joints similar to the one formed when molten lava cools.

Earth is a large spherical landmass, which is divided into three major layers, known as crust, mantle, and core. The innermost layer of the Earth is the core.
<h3>What is the core?</h3><h3 />
- The core of the Earth is the innermost layer, present beneath the mantle and crust.
- The core is entirely made up of iron and nickel. The core of the Earth is also called NIFE, which symbolizes the elements present in the core, Iron (Fe) and Nickel (Ni).
- Core has a radius of approximately 1220 kilometers and is responsible for the generation of the magnetic field.
- Core also consists of the earliest history of the planet and is extremely hot, such that the temperature is close to the Sun's temperature.
Thus, the correct answer is Option D.
