Is eighth grade harder than seventh grade?
Ummm ya it is! Wasn't 7th grade harder than 6th grade? I think that every time that you move up a grade everything gets harder.
Is pre-algebra harder than regular math?
I think it is harder than math. You usually need to get straight A's on math to get into pre algebra
What is 5 times harder than a metal?
What is 5 times stronger than metal? Steel - Because steel is a compound which steel is like a hard rock! Unbreakable! Steel can be even harder then ever which means it can be stronger then 5 more like 100 but that is only SOME types! Steel is way harder, yes 5 times harder!
What color of streak is marble?
Marble, being composed almost entirely of the mineral calcite, would have a white streak. The same colour as calcite's streak.
Are Continental Math League problems harder than Mathcounts problems?
no
Is fluorite harder than calcite?
The mineral fluorite is harder than calcite. Fluorite is represented as a 4 on the Mohs scale of relative mineral hardness, calcite is a 3.

How would a scientist tell the difference between calcite and quarts?
A scientist can differentiate between calcite and quartz by testing their hardness using the Mohs scale, where quartz has a higher hardness value of 7 compared to calcite's 3. Another method is through a reaction with acid, as calcite fizzes when in contact with dilute hydrochloric acid due to its calcium carbonate composition, while quartz remains unaffected. Lastly, they can use polarized light microscopy to identify the distinctive crystal structures of each mineral.
How would scientist tell the difference between calcite and quarts?
Quartz is much harder than calcite.
Which material would you scratch the other quartz or calcite how do you know?
Quartz because its harder than calcite and the quartz in thicker.
Which is better for jewelry calcite or quartz?
