Question

the fundamental difference between the different types of sedimentary rocks

Answer 1

Answer:

The rocks that are formed by the sediments over time are called sedimentary rocks.  

The three types of sedimentary rocks are:

Chemical sedimentary rocks

Sedimentary rocks formed by the chemical reaction of the materials such as iron, flint, salt, etc.

Organic sedimentary rocks

Rocks formed from the leftovers of the plants and animals

Clastic sedimentary rocks

Rocks formed by the mechanical weathering of the leftovers. (Siltstone, sandstone, etc.)

Answer 2

Answer:

As explained below.

Explanation:

• The sedimentary rocks are formed by the accumulation of sediments that are derived by the erosion deposition by the agent of weathering and mass wasting.

• There can be three types of sedimentary rocks based on formation. Such as Clastic, chemical and organic. The clastic rocks include sandstone, shale, and conglomerates. While the chemical rocks are iron ores dolomites and the limestone.

• Organic sedimentary rocks are coal, limestone and the dolomites. As coal is a rock that is mainly formed by the plant debris., usually found in marshy environments. It's often mined as fuel. Limestone is a rock that is composed of calcium carbonate by the accumulation of algae, and the shells of microorganisms.

• Thus all the rocks types are formed by the changes in the texture, color and formation phases like the red sedimentary rock which has iron contents.
