Because snow is composed of frozen water, or ice, it can also be classified as a mineral. A mineral is a naturally occurring homogeneous solid, inorganically formed, with a definite chemical composition and an ordered atomic arrangement.

Is rain water a mineral?

Rain water passes through the atmosphere and picks up whatever is present there, including particulates such as dust, trace amounts of atmospheric gases, nitrates and nitrites, and so forth. Rain water is relatively low in mineral content.

What are the 4 types of coal?

Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.

Does coal come from wood?

“Trees would fall and not decompose back,” write Ward and Kirschvink. Instead, trunks and branches would fall on top of each other, and the weight of all that heavy wood would eventually compress those trees into peat and then, over time, into coal.

What is coal an example of *?
