Sediments

Sediment derived from land and brought to the ocean by wind and water. Ex:quartz, sand, clays.

• Terrigenous

• Biogenous

• Cosmogenous

• Hydrogenous

Sediments of biological origin. Ex: calcareous(containing calcium) and siliceous(containing silicone) oozes.

• Terrigenous

• Hydrogenous

Sediment formed by precipitation from seawater. Ex: maganese+phosphate nodules.

What is the difference between a neretic and pelagic sediment?

• Neretic is a sediment of the shore or the coast and pelagic is a sediment that refers to the water above the deep ocean basins.

• Nothing

Is a naturally occuring inorganic crystaline material w/specific chemical structure. They form from the cooling of magma, contact metamorphism, precipitation of minerals in water, and then the evaporation of seawater.

• Mineral

• Magma.

What are the 7 steps used to identify a mineral?

• Luster, hardness, streak, fracture or cleavage, density or specific gravity, color, special properties.

• Hardness, nails, taste, smell, scratched by a penny, colorless, and has no properties

A brassy yellow metallic mineral, it exhibits fracture. It leaves a green black streak and a 42 g sample has a volume of 10 mL. It can be scratched by a penny or a nail.

• Chalcopyrite

• Halite

A perfect cube shaped non-metallic mineral can be scratched by a penny. It leaves a colorless streak and it appears clear in color. A 27 gram sample takes up 10 ml space. It looks like a perfect cube and tastes salty.

• Chalcopyrite

• Halite
