Question

1. coal formation is largely the result of ____.

○ climate
○ humidity
○ magma
○ sedimentation

Explanation:

Coal forms when dead plant matter accumulates in anaerobic, waterlogged environments, then undergoes burial, compaction, and chemical changes over millions of years—this is a sedimentary process. Climate and humidity influence plant growth but are not the direct cause of coal formation, while magma is related to igneous rock formation, not coal.

Answer:

D. sedimentation
