Explanation: The Khasi Hills are a significant geographical feature located in the northeastern part of India, primarily within the state of Meghalaya. They form the southern boundary of the Meghalaya plateau, which is a part of the larger Shillong Plateau. The Khasi Hills are known for their lush greenery and high rainfall, making them one of the wettest places on Earth. The region is home to the Khasi people, who have a rich cultural heritage and are known for their unique customs and traditions.
The Meghalaya plateau itself is a part of the larger Shillong Plateau, which is a series of plateaus and hills that form the eastern part of the Deccan Plateau. The plateau is characterized by its high elevation, ranging from 450 to 1,525 meters above sea level. The Khasi Hills, being a part of this plateau, are an important geographical feature that defines the landscape of Meghalaya.
The Khasi Hills are not only significant for their geographical features but also for their ecological importance. The region is known for its dense forests, which are home to a wide variety of flora and fauna. The high rainfall in the area supports a rich biodiversity, making it an important area for conservation efforts.
In contrast, the other options listed in the question are not related to the geography of Meghalaya. The Kaimur Hills are located in the state of Bihar, the Mahabharat Range is in Nepal, and the Patkoi Range is in Arunachal Pradesh and Nagaland. These ranges are not directly connected to the Meghalaya plateau or its southern boundary.
Understanding the geographical layout of Meghalaya and its surrounding areas is crucial for comprehending the region's unique features and its significance in the broader context of Indian geography. The Khasi Hills, as a part of the Meghalaya plateau, play a vital role in defining the landscape and ecology of the region.
