Does hermatite occur naturally

I would say yes.

Explanation:

Hematite is found as a primary mineral and as an alteration product in igneous, metamorphic, and sedimentary rocks. It can also form during contact metamorphism when hot magmas react with adjacent rocks. The most important hematite deposits formed in sedimentary environments.

I hope I'm correct

Hematite is found as a primary mineral. it is naturally formed in sedimentary environments.

Gypsum is a naturally occurring stone, a metallic salt of calcium. It commonly forms as an evaporite from the dissolution of limestone by exposure to sulphuric acid from volcanic activity

So the answer is YES

the atmospheric gas that forms a mild acid when dissolved in water is called carbon dioxide. the correct answer is a. 2.) chemical weathering would cause an inscription on a marble headstone to become harder and harder to read over time.
