Mold and mushrooms are both fungi, the mold is called “Hyphomycetes”
The period during which the presence of stromatolites decline is the Proterzoic period. Stromatolites are widely distributed sedimentary structures consisting of laminated carbonate or silicate rocks, produced over geologic time by the trapping, binding, or the precipitating of sediment by groups of microorganisms, primarily cyanobacteria.
Answer:
2cm/year
Explanation:
10,000 years = 200m
The question asks, what is its rate in cm per year?
So first we have to make sure the units are the same, i.e by changing the metres(m) to centimetres(cm)
1m = 100cm
200m = (200x100) <em>20,000 cm</em>
10,000 years = 20,000 cm
Now we divide the latter by the former. (cm/year) i.e, years by centimetres
20,000 ÷ 10,000 = 2
