Question

What are these sedimentary rock types? (Clastic or chemical- clastic is subdivided as organic/biochemical clastic, or detrital clastic) and the reasoning for it.

1. Calcareous tufa
2. Limestone
3. Conglomerate
4. Sandstone
5. Clay

Answer 1

Calcareous tufa is a chemical sedimentary rock. Limestone can be both chemical and organic. Conglomerate and sandstone are clastic sedimentary rocks. Clay is a fine-grained, clastic sedimentary rock. correct option for each sedimentary rock type in the final answer provided .

Step-by-step explanation:

The sedimentary rock types mentioned are:

1. Calcareous tufa: This is a type of chemical sedimentary rock that forms from the precipitation of calcium carbonate from water.
2. Limestone: Limestone can be both chemical and organic sedimentary rock. It forms from the accumulation of remains of marine organisms such as shells and coral.
3. Conglomerate: Conglomerate is a clastic sedimentary rock made of rounded pebbles and cobbles cemented together.
4. Sandstone: Sandstone is another clastic sedimentary rock composed of sand-sized grains that are cemented together.
5. Clay: Clay is a very fine-grained clastic sedimentary rock made up of tiny particles.
