Final answer:
Chemical sedimentary rock forms from solutions through precipitation and solidification of dissolved minerals.
Step-by-step explanation:
The main type of sedimentary rock that forms from solutions is chemical sedimentary rock. Chemical sedimentary rocks are formed when dissolved minerals in water, such as calcium carbonate or silica, precipitate out and solidify, often due to evaporation or chemical reactions. Examples of chemical sedimentary rocks include limestone, chalk, and rock salt.
