Solution
The sediment that precipitates inorganically when warm seawater evaporates is salt grains.
Here's the step by step explanation:
-
Seawater contains a variety of dissolved salts, the most abundant of which is sodium chloride, commonly known as table salt.
-
When seawater is warmed by the sun, the water begins to evaporate.
-
As the water evaporates, the concentration of salt in the remaining water increases.
-
Once the concentration of salt reaches a certain level, the water can no longer hold the salt in solution and it begins to precipitate out, forming solid salt grains.
-
These salt grains then settle to the bottom, forming a sediment layer.
So, the correct answer is "salt grains".
