'Scarce resource' implies that the resource is uncommon, rare and hard to find, all of which is true for the mineral diamond.
As to why diamond is scarce, that's a Mother Nature question, and she's not answering questions here, sorry.
Coal is considered a scarce resource because its formation takes millions of years and the rate at which it is being consumed far exceeds the rate at which it is being naturally replenished. Furthermore, the extraction of coal can be environmentally damaging, leading to concerns about its long-term sustainability as an energy source.
Potassium nitrate is not considered a scarce resource as it is widely available for various industrial and agricultural applications. It can be purchased from chemical suppliers or fertilizer stores without much difficulty. However, restrictions may apply depending on regulations in specific regions due to its use in explosives.
Coal is sometimes referred to as a "black diamond" due to its economic importance and value as an energy resource, similar to how diamonds are prized for their rarity and value. This term highlights the significance of coal in industries such as power generation and steel production.
Coal is considered a non-renewable resource, meaning it is finite and can be depleted over time. Although there are still significant coal reserves worldwide, certain regions may face scarcity due to factors such as extraction costs, environmental regulations, and shifting energy trends towards cleaner alternatives.
Yes, coal is often called "black diamond" due to its appearance and value as a source of energy. The comparison is made to highlight the significance of coal as a valuable resource similar to how diamonds are valued for their rarity and beauty.
Because it is important
yes
Rain
Water is the most scarce resource in north Africa and southwest Asia.
fossil fuels
Water is considered as a scarce resource as fresh water occupies only 3% of total water found on earth.

A limiting factor
This is because oil is a nonrenewable resource.
it is very scarce
In some geographies, yes, diamond is a major resource.
Resource Depletion. ;)
