Question

Which one of the following provides the cryogenic indicator of climate change?

  1. Ice core
  2. Fossilized pollen
  3. Tree ring growth
  4. Evaporite deposits

Answer:

Option A: Ice core

Detailed Solution:

The correct answer is “Ice core”.

Ice core provides the cryogenic indicator of climate change. Cryogenic indicators are those that can be analyzed from frozen materials.

Ice cores, drilled from glaciers and ice sheets, contain trapped air bubbles and dust particles that can reveal information about past temperatures, atmospheric composition, and precipitation patterns.

By analyzing these elements, scientists can reconstruct climate history and identify trends associated with climate change.
