Is it true or false that the physical properties of minerals are properties that are visually identifiable?
Only some properties are visually identifiable: color for example.
Is 8 is a factor of 18 True or False?
False.
The hemisphere that is tilted away from the sun has more daylight than the other hemisphere true or false?

false.

false
Very few minerals are compounds true or false?
False. Most minerals are compounds, which means that they are combinations of elements. Additionally, some minerals are elements by themselves.
True of false very few minerals are compounds?
False. Most minerals are compounds, meaning they are composed of two or more elements bonded together. This is what gives minerals their unique chemical and physical properties.
Only 10 elements compose the bulk of the rock-forming minerals in the continental crust Is this true or false?
False. The bulk of the rock-forming minerals in the continental crust are composed of a variety of elements, not just 10. The most common elements found in these minerals include oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
True or False Dissolved minerals trapped in magma under tremendous pressure provide the force for a volcanic eruption?
True. The dissolved minerals trapped in magma create gases that are released under pressure, causing the magma to rise and eventually leading to a volcanic eruption.
What are false a-minerals are all made up of rocks b- rocks are generally mixtures c-minerals can be compounds or elements d- minerals are inorganic?
A is false - Rocks are composed of minerals not the other way round. B, C and D are all true.
Diamond and quartz are both minerals composed of a single element true or false?
False. Diamond and quartz are minerals composed of multiple elements. Diamond is composed of carbon atoms, while quartz is composed of silicon and oxygen atoms.
True or false viens minerals were once in solution?
True. Veins minerals are deposited from solutions like water that flow through cracks in rocks, carrying dissolved minerals which crystallize and form veins as the solution evaporates or cools.
How Minerals that can be mined at a profit are called ores true or false?
True. Ores are minerals that contain valuable metals or elements that can be extracted economically through mining and processing.
Dissolved minerals are left behind when water evaporates. true or false?
Not necessarily. I can evaporate a whole bucket full of pure distilled water and no mineral molecules will do anything!
Is this true or false geologists have identified about 300 minerals?
False, Geologists identified about 3,800 minerals.
Dissolved salt in ocean water is an example of a chemical change true or false?
false
In higher pressure environments less gas can be dissolved in a solvent true or false?
False.
