Part of: Meghalaya Gk set 6

..... cave in Meghalaya is formed out of lime stones and are quite long and deep.

Category: Meghalaya Gk

Hint: Consider the type of rock formation and the characteristics of the cave.

Correct Answer: A) Mawsmai

Exam Relevance: UPSC, SSC, State PSC

Difficulty: Easy

Explanations:

Mawsmai cave is a significant geological feature located in the East Khasi Hills district of Meghalaya, India. It is a limestone cave system that is known for its length and depth. The cave is formed through a process called karstification, which involves the dissolution of limestone by slightly acidic water. This process is common in areas with limestone bedrock, where water, often containing carbonic acid from dissolved carbon dioxide, slowly dissolves the limestone over time, creating underground cavities and passages.

The Mawsmai cave system is a prime example of a karst landscape, which is characterized by the presence of caves, sinkholes, and underground drainage systems. The cave is formed when water, which is slightly acidic due to dissolved carbon dioxide from the atmosphere and soil, seeps into the limestone bedrock. As the water moves through the rock, it slowly dissolves the limestone, creating passages and chambers. Over thousands of years, these passages can become large enough to form extensive cave systems like Mawsmai.

The cave system at Mawsmai is not only a geological wonder but also a popular tourist attraction. It is accessible through a series of steps and pathways that lead into the cave. The cave is illuminated with lights, making it easier for visitors to explore the intricate passages and formations. The cave system is known for its stalactites and stalagmites, which are formed by the deposition of calcium carbonate from water dripping through the cave ceiling and floor.

It is important to note that while Mawsmai is a well-known cave in Meghalaya, there are other significant cave systems in the region, such as Krem Lymput and Krem Mawmluh. However, Mawsmai is particularly notable for its accessibility and the extent of its cave passages. The cave system is a testament to the geological processes that have shaped the landscape of Meghalaya over millions of years.

Understanding the formation of limestone caves like Mawsmai is crucial for comprehending the broader geological processes that shape the Earth's surface. The process of karstification is not unique to Meghalaya but occurs in many regions around the world where limestone bedrock is present. This process is responsible for the creation of diverse and complex cave systems, which are not only of scientific interest but also of cultural and economic significance, particularly in terms of tourism and natural resource management.

Option Analysis:
  • Option A: Mawsmai cave is the correct answer because it is a limestone cave system in Meghalaya, known for its length and depth. The cave is formed through the dissolution of limestone by slightly acidic water, a process known as karstification.
  • Option B: Dechen-phu is incorrect as it is not a cave in Meghalaya. It is a village in Arunachal Pradesh, and thus, it does not fit the description of a limestone cave system in Meghalaya.

Mnemonic: Mawsmai: "Mighty" caves made of limestone
