Given below are two statements : One is labelled as Assertion A and the other is labelled as Reason R.

Assertion A : The change in sea level at any coastal location depends on the sum of global, regional and local factors.

Reason R : Therefore, the global mean sea level rise translates into an uniform rise in sea level around the world.

In the light of the above statements, choose the most appropriate answer from the options given below.

The correct answer is A is correct but R is not correct.

Key Points Assertion A: The change in sea level at any coastal location depends on the sum of global, regional, and local factors.

Reason R: Therefore, the global mean sea level rise translates into a uniform rise in sea level around the world.

  • The change in sea level at any coastal location is influenced by a complex interplay of global, regional, and local factors, including changes in the amount and distribution of water in the oceans, land subsidence, tectonic uplift, and oceanic and atmospheric circulation patterns.
  • Therefore, Assertion A is true.
  • The global mean sea level rise does not translate into a uniform rise in sea level around the world.
  • Local sea level changes can be influenced by a variety of factors, such as changes in ocean currents and weather patterns, and can differ substantially from the global average.
  • Furthermore, the effects of sea level rise can be amplified or mitigated by local factors such as coastal erosion, sedimentation, and land use changes.
  • Therefore, while Assertion A is true, Reason R is not a valid explanation for it.
