Question

Quizplus · Accepted Answer

All three of these phenomena involve the formation of minerals from water solutions through the process of precipitation. Hot springs often deposit minerals as the hot water cools, salt layers in the Mediterranean Sea were formed by the precipitation of minerals from evaporating seawater, and Native American tools and weapons were often made from minerals that were precipitated out of water solutions, such as flint or obsidian. Biologic activity or chemical reactions may have played a role in some cases, but the common thread is the process of mineral precipitation from water solutions.
