Is limonite a mineral?
Geologylimonite, one of the major iron minerals, hydrated ferric oxide (FeO(OH)·nH2O).

How is the ocean stratified and what causes the different strata?
Geology and GeographyThe ocean is stratified due to differences in density, with warmer, lighter, less salty water layering on top of heavier, colder, saltier water. Mixing between layers occurs as heat slowly seeps deeper into the ocean and by the action of current, winds, and tides. What causes water stratification? Stratification occurs as a result of a
