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.
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 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!
no
Marble, being composed almost entirely of the mineral calcite, would have a white streak. The same colour as calcite's streak.
Mica and calcite are both minerals commonly found in Earth's crust. They both have distinct cleavage patterns, with mica typically having perfect basal cleavage and calcite having rhombohedral cleavage. However, they differ in chemical composition, as mica is a silicate mineral while calcite is a carbonate mineral. Additionally, mica displays a pearly luster and tends to be softer than calcite, which has a vitreous luster and can scratch glass.
Yes, fluorite is harder than calcite. Fluorite has a hardness of 4 on the Mohs scale, while calcite has a hardness of 3. This means that fluorite can scratch calcite, but calcite cannot scratch fluorite.
It can be hard to remember the hardness levels of all the minerals and substances of the Earth. Calcite is something that is harder than gold.Ê

Calcite (CaCO3) is a carbonate.
Calcite is a mineral that is harder than gypsum but softer than fluorite on the Mohs scale of mineral hardness. Calcite has a hardness of 3, while gypsum has a hardness of 2 and fluorite has a hardness of 4.
Quartz is much harder than calcite.
Glass is generally harder than calcite. Calcite has a Mohs hardness of 3, while glass typically has a Mohs hardness of around 5.5. This means that glass is more resistant to scratching and abrasion compared to calcite.
Yes, calcite is softer than copper. Calcite has a Mohs hardness of 3, while copper has a Mohs hardness of 2.5 to 3.
Quartz because its harder than calcite and the quartz in thicker.
they are quartz, mica, feldspar, and calcite.
Fluorite and apatite are two minerals that are harder than calcite but softer than quartz on the Mohs scale of mineral hardness. They have hardness values of 4 (fluorite) and 5 (apatite) respectively, compared to 3 for calcite and 7 for quartz.
