Question

which of the following are sources of lithogenous particles in the ocean?
□ windblown dust
□ ash from volcanic islands
□ broken coral pieces
□ rocks transported by icebergs

Explanation:

Lithogenous particles in the ocean come from non - biological, non - chemical (in the sense of organic or biogenic) sources related to rocks and minerals.

• Windblown dust: Dust carried by wind can deposit into the ocean, and this dust is lithogenous as it is composed of mineral particles.
• Ash from volcanic islands: Volcanic ash is made of mineral - rich particles, so it is a source of lithogenous particles.
• Broken coral pieces: Coral is biogenic (formed by living organisms), so it is not a source of lithogenous particles.
• Rocks transported by icebergs: Icebergs can carry rocks, and when they melt or deposit these rocks into the ocean, these rocks contribute lithogenous particles.

Answer:

A. Windblown dust, B. Ash from volcanic islands, D. Rocks transported by icebergs
