<span>A method of processing coal to remove contaminants by mixing coal in a solution of potassium permanganate in a selected concentration range, rinsing the coal, mixing the coal in a solution of ammonia hydroxide in a selected concentration range to cause the solution to be brought into contact with the surfaces and pores of the coal, discharging the processed coal from the second reaction vessel, monitoring the process to detect when the concentration of aqueous ammonia in the second reaction vessel has fallen below the selected range, and feeding aqueous ammonia solution with an ammonia concentration in or above the selected range to the second reaction vessel to return the solution to within the selected range.</span>

Answer: to me personally I think They would become igneous rocks
Explanation:
If originally, sedimentary rocks are exposed to energy from the sun, no changes will occur to them.
- The temperature of the sun does not change the materials of the earth substantially.
- There is a very significant effect of the heat from the interior on rocks, especially sedimentary rocks.
- Heat can hit a whopping 6000 ° C from the inside, which is more than enough to cause a metamorphic shift in a rock in the body.
- Actually, the igneous rock will be formed from the sedimentary rock at this temperature.
Hey there! I'm happy to help!
The Fertile Crescent is basically where human civilization started. It stretches from Mesopotamia and across the Mediterranean coast to Egypt. Early civilizations depended on agriculture. To make agriculture, you need a river because it is a good water source to help grow your crops.
If you look at the map I have provided below, you will see that there are tons of rivers. This would make it very easy for settlers to grow crops. This means that sea tides and eroding mountains aren't the answer. I don't think the rivers were flooding and natural canals is an oxymoron because canals are artificial waterways, but this all should give you and idea.
Have a wonderful day! :D
