How do heated underground fluids contribute to mineral deposit formation?

• They decrease in density and evaporate.

• They remain stationary and form crystals.

• They rise to the surface and solidify dissolved metals.

• They cool down and dissolve minerals.

What causes the underground fluids to rise toward the surface?

• They are denser than the surrounding rock.

• They are pulled by gravitational forces.

• They are less dense than the surrounding rock.

• They are pushed by tectonic plate motion.
