What might an increase in terrigenous sediments suggest about climate conditions?

• A. Lower sea temperatures
• B. Heightened erosion linked to climate change
• C. Improved sedimentation rates
• D. Stability in the ecosystem

Answer: (B)

An increase in terrigenous sediments typically indicates heightened erosion linked to climate change. Terrigenous sediments are derived from land, and their presence on the ocean floor suggests that more land material is being transported to the seas. This increase is often a result of stronger weather events, such as heavy rains or storms, which can erode land and transport sediments into rivers and ultimately to the ocean. Additionally, changes in vegetation cover due to climate fluctuations can also exacerbate erosion. Therefore, the rise in terrigenous sediments serves as an indicator of the impact of climate conditions on terrestrial landscapes, emphasizing the relationship between climate change and erosion processes. Understanding this connection is crucial for evaluating past climate variations and predicting future changes.
