Explanation:
The Milankovitch cycles -
This is the movement related to Earth's orbit around the Sun .
There are three cycles , Axial tilt , Eccentricity and precession .
According to this theory , these cycles together affect the amount of the solar heat that is incident towards the Earth's surface and the climatic pattern .
The Milankovitch cycle helps the advance and retreat of ice over the periods of 10,000 to 1000,000 years , but it does not explain the cause of Ice Age.

<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>
