Multiple Choice
Stromatolites are an example of which of the following sediment types?
A
Chemical sediment
B
Biogenic sediment
C
Volcanic sediment
D
Clastic sediment
Verified step by step guidance
1
Begin by understanding the term 'stromatolites'. Stromatolites are layered structures formed by the growth of cyanobacteria, which are microorganisms that perform photosynthesis.
Recognize that stromatolites are formed by biological activity, specifically by the accumulation and trapping of sediment particles by microbial mats.
Consider the types of sediment listed: Chemical, Biogenic, Volcanic, and Clastic. Each type has distinct characteristics.
Biogenic sediment is formed from the accumulation of biological material, such as shells, bones, or plant material. Stromatolites fit this category because they are formed by the biological activity of cyanobacteria.
Conclude that stromatolites are an example of biogenic sediment due to their formation process involving living organisms.
