silicon is happy just to combine with oxygen

An example of anthropomorphism in popular science writing:

"As it happens, there's plenty of silicon in the Earth's crust – but it shows no interest whatsoever in forming complex molecules. It combines with oxygen to form silica – the primary constituent of most rocks – and seems happy enough to stop there."

[Silicon is not the kind of thing that show interest or be happy, so this is figurative language, and so describes metaphorically rather than explaining anything.]
