Question

When the mineral-rich water from a hydrothermal vent hits the surrounding sea-water, the minerals rushing out give the water the appearance of _____.
A.)white smoke
B.)a neritic zone
C.)boiling water
D.)black smoke

Answer 1

Answer:

D.)black smoke is the correct answer.

Explanation:

The mixture of mineral rich water reaches the sea water, the minerals rushing out gives the water the appearance of the black smoke due to the deposits of iron sulfide.

The mineral-rich water generates precipitation of the small particles of the iron sulfide minerals and manganese minerals.

These particles extremely fine-grained of sulfide minerals produced when a hot hydrothermal liquids get mixed with the near freezing sea-water.

Answer 2

The correct answer is option D

The mixture of mineral rich water reaches the sea water, the minerals rushing out gives the water the appearance of the black smoke.

The mineral rich water causes precipitation of the tiny particles of the iron rich sulfide minerals and manganese rich minerals.

This gives the black color to the smoke and it appears to be black.
