Question

explain chemical sedimentary rocks ​

Answer 1

Answer:

Chemical sedimentary rocks: Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water.

For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water. This is how rocks such as limestones form.

Answer 2

Answer:

Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water.

For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water. If you set the water in a hot and dry place (like Arizona) the water, but not the salt, will evaporate away. As the water evaporates, the concentration of salt gets higher and the water will eventually become saturated and will not be able to dissolve any more salt. At this point, as the water continues to evaporate, the salt will come out of solution and will be precipitated in the glass.
