Zorluk: OrtaPhysiography and Relief Features of India

Regarding the physiographic characteristics of the Peninsular Plateau and Indian Islands, which of the following statements are correct?

  1. The Western Ghats form a continuous relief wall that is crossed mainly through mountain passes such as Thal Ghat and Bhor Ghat.Cevap
  2. B
    The Eastern Ghats possess a higher average elevation than the Western Ghats and form an unbroken mountain wall along the east coast.
  3. The Ten Degree Channel is a maritime water body that geographically separates the Andaman Islands group from the Nicobar Islands group.Cevap
  4. D
    The Lakshadweep island archipelago consists of elevated volcanic basaltic plateaus formed during Deccan Trap volcanic activity.

Cevap

The statements confirming that the Western Ghats form a continuous wall crossed via specific mountain passes and that the Ten Degree Channel separates the Andaman Islands from the Nicobar Islands are correct.
The Western Ghats are higher in average elevation (900–1600 m) and continuous, making passes such as Thal Ghat and Bhor Ghat essential for crossing. Additionally, the Ten Degree Channel situated along 10° N latitude physically separates the Andaman group of islands from the Nicobar group.

Adım Adım Çözüm

1
Analyze the elevation and continuity of the Western and Eastern Ghats.
The Western Ghats form an unbroken wall with an average elevation of 900–1600 meters crossed by passes like Thal Ghat and Bhor Ghat, whereas the Eastern Ghats are lower (average ~600 m) and heavily dissected by rivers.
Topographic continuity and elevation distinguish the Western Ghats as a major relief divide compared to the discontinuous Eastern Ghats.
2
Evaluate the geographical location of the Ten Degree Channel.
The Ten Degree Channel separates Little Andaman in the north from Car Nicobar in the south.
This latitudinal water gap serves as the explicit physiographic boundary separating the two island subgroups.
3
Examine the geological origin of Lakshadweep Islands.
Lakshadweep Islands are composed of biogenic coral reefs (atolls), not volcanic basaltic rocks.
Volcanic landforms in Indian island territory are confined to specific features like Barren Island in the Andaman Sea.
