Consider the following statements:

1. Due to the retreating of sea, landmass dries up and becomes plain.

2. Indian plain of Kachchh is formed in the same process.

Which of the above statement is/are correct?

UKSSSC VDO Official Paper (Held On: 09 Jul, 2023)

Answer 1

The correct answer is Both statements 1 and 2 are incorrect.

Key Points

Statement 1 is incorrect because the retreat of the sea does not result in the drying up of landmass to form plains. Such processes are more commonly associated with sediment deposition, tectonic uplift, or other geological events.
Statement 2 is incorrect as the Kachchh region in India is primarily an arid or semi-arid area formed due to tectonic and geological processes, including the uplift of sea beds and sedimentation over geological time.
The Rann of Kachchh, which is part of the region, is a salt marsh, not a plain formed by sea retreat.
Coastal processes like regression or transgression of the sea usually lead to the creation of coastal features such as deltas, lagoons, or estuaries, but not plains in the manner described in the statements.
Thus, both the statements provided in the question are factually incorrect.

Additional Information

Formation of Plains: Plains are typically formed through the processes of river deposition, glacial activity, wind erosion, or tectonic activity, not directly due to sea retreat.
Kachchh Region: The Kachchh region is known for its unique geological and ecological features, including the Great Rann and Little Rann of Kachchh, which are saline marshlands.
Rann of Kachchh: The Rann is a seasonal salt marsh that floods during the monsoon season and dries up in the summer, leaving behind salt-encrusted land.
Sea Retreat (Marine Regression): Marine regression refers to the sea level dropping relative to the land. This can lead to the exposure of previously submerged areas but does not create plains in the sense implied by the question.
Geological Tectonics in Kachchh: The region has been shaped by tectonic movements, including uplift and faulting, which have influenced its landscape over millions of years.
