Explanations:Sikkim, a state in northeastern India, is renowned for its rugged and mountainous terrain. The geography of Sikkim is dominated by the Kanchenjunga massif, which is the third-highest peak in the world. The state's landscape is characterized by high, perpetually snow-covered mountains. This means that a significant portion of the mountains in Sikkim are covered with snow throughout the year, due to the high altitude and cold climate.
The term "perpetually snow-covered" is used to describe the state of the mountains that remain covered with snow all year round. This is a common feature in high-altitude regions where the temperature remains below freezing for most of the year, leading to the accumulation of snow that does not melt completely even during the warmer months.
In the context of the question, the correct answer is "Covered" because it accurately describes the state of the mountains in Sikkim. The term "covered" is used to indicate that the mountains are enveloped or enveloping in snow, which is a key characteristic of the region's geography.
It is important to understand the geographical features of Sikkim to appreciate its unique landscape and the challenges it poses for human habitation and development. The perpetually snow-covered mountains not only contribute to the state's natural beauty but also influence its climate, biodiversity, and the lifestyle of its inhabitants.
