Question

1. which of the following images shows a transition from the biosphere to the geosphere?

options: image a, image b, image c, image d

Explanation:

• Image A: Coal (geosphere) is burned in a power plant. This is a transition from geosphere to atmosphere (due to emissions).
• Image B: Forest fire (biosphere) releases \(CO_2\) to the atmosphere. This is a transition from biosphere to atmosphere.
• Image C: Limestone (geosphere) is part of the lithosphere. This is within the geosphere (no biosphere involvement).
• Image D: Marine plants/algae (biosphere) and animals (biosphere) become sediments (geosphere over time as they accumulate and lithify). This shows a transition from biosphere (living organisms) to geosphere (sediments which can become rock).

Answer:

Image D
