Why is calcite always found at the bottom of an evaporite?
Calcite is often found at the bottom of an evaporite deposit because it is less soluble in water compared to other evaporite minerals like halite or gypsum. As the water evaporates, these less soluble minerals tend to precipitate out first and settle at the bottom of the evaporite layer.
Which mineral would halite be able to scratch?
Halite, which has a Mohs hardness of 2.5, can scratch minerals that are softer than it on the hardness scale. This means it can scratch talc (hardness 1) and gypsum (hardness 2). However, it would not be able to scratch minerals like calcite (hardness 3) or any harder minerals.
What air conditions would least likely to have precipitation?
Cold dry air
What air condition would be least likely to have precipitation?
Cold dry air
Does halite conduct electricity?
halite is a good insulator for electric current..

Calcite halite and fluorite all have perfect cleavages and they can all be the same color. How would you distinguish among them?
You can distinguish these minerals by testing their physical properties such as taste (halite is salty), hardness (calcite scratches easily with a knife, halite is soft, fluorite is harder), and fluorescence (fluorite exhibits fluorescence under UV light). Additionally, you can use a hand lens to examine their crystal shapes or conduct a streak test to observe their powder color.
What type of precipitation would fall at 27 degrees Fahrenheit?
At 27 degrees Fahrenheit, the precipitation would likely fall as snow.
How can you tell the difference between calcite crystals and salt crystals?
Calcite crystals will effervesce in vinegar, quartz will not. Quartz will scratch calcite. The opposite is not true. Quartz and calcite have different crystal structures and different specific gravities. The list goes on, but if you are trying to distinguish them, the above should help.
What air conditions would least likely to have precipitation?
Cold dry air
What air condition would be least likely to have precipitation?
Cold dry air
Which material would scratch the other quartz or calcite?
Quartz, with a hardness of 7, will scratch calcite, with a hardness of 3.
During the Permian Period sedimentary bedrock in the Appalachian Region was subjected to high temperature and pressure Calcite deposits that had existed in this environment would most likely have fo?
The calcite deposits would likely have undergone metamorphism, transforming into marble due to the high heat and pressure. Marble is a metamorphic rock formed from limestone or dolomite, which are composed primarily of calcite. This process changes the mineral composition and texture of the rock.
What strategy would allow you to determine clear calcite is not the same as quartz?
A small drop of hydrochloric acid or vinegar would fizz on calcite, not on quartz.Also, quartz has a Mohs hardness of 7 whereas calcite has a hardness of 3. Quartz doesn't have cleavage but calcite has rhombohedral cleavage (skewed square). If the piece of mineral breaks along perfect lines, then it's most likely calcite not quartz. One more thing, if you put the clear calcite on print, like that in a book, you will see a double image through the crystal, an example of double refraction.
Is halite cleavage or fracture?
Halite is a cleavage because it splits evenly, but fracture would mean it breaks irregularly.
Can you form a stalactites and stalagmites?
In theory you could in a laboratory if you establish conditions conducive to rapid precipitation and crystallising of the calcite - but I don't know why you would need to when it's easier to analyse natural ones!
Which type of precipitation would likely be falling from cumulus clouds with a ground air temperature of 14 C?
Ice crystals and snow pellets are the types pf precipitation that would likely be from the falling cumulus clouds with a ground air temperature of 14 C.
