1. using the geologic definition of mineral as your guide, determine which of the items in this list are minerals and which are not. if something in this list is not a mineral, explain. 1. gold nugget 2. seawater 3. quartz 4. cubic zirconia 5. obsidian 6. ruby 7. glacial ice 8. amber

Explanation:

Geologists defines a mineral as a naturally occuring solid, which is inorganic with a uniquely ordered structure and a definite chemical composition.

Gold nugget based on this definition is mineral. It is a solid and it occurs naturally. It is made up of gold atoms.

Seawater is not a mineral. It is a liquid and does not have definite composition.

Quartz is a mineral with a definite composition. It occurs naturally and it is a solid.

Cubic zirconia is not a mineral. It is not naturally occuring. It is man made.

Obsidian is not a mineral. It is a mineraloid due to its form. It is glass-like in nature. In obsidian, the crystals do not have time to form an ordered structure.

Ruby is a silicate mineral. It is naturally occuring and fits the description of minerals.

Glacial ice is a mineral. It is solid, inorganic, naturally occuring, and has a definite composition.

Amber is an organic compound and not a mineral.

the proximity of water was an advantage to western europe and its culture was able to flourish as a result. trade and travel by sea were easier and safer in historical times.

1. there are no mountains to protect it from the sea

2. and its has wet cool summers and wet, mild winters.
