General Information:

The writer continues to speak of Yaweh's great power.

Then the water channels appeared; the foundations of the world were laid bare

These two clauses have similar meanings. This can be stated in active form. Alternate translation: "Then the water channels appeared and the bottom of the ocean became visible; you exposed the foundations of the world" (See: rc://en/ta/man/jit/figs-parallelism and rc://en/ta/man/jit/figs-activepassive)

at the blast of the breath of your nostrils

Though God does not have human physical characteristics as described here, this pictures his mighty strength. The wind is spoken of here as if it came as a mighty blast from God's nostrils. (See: rc://en/ta/man/jit/figs-personification and rc://en/ta/man/jit/figs-metaphor)
