Answer:
The glaciers will accumulate more in amount when the planet cools, and this will result in the slow expansion of glaciers, extending horizontally and downward, due to the pressure exerted by the glaciers. The glaciers will be rapidly accumulated in the glacier head in comparison to the zone of wastage, which covers the region below the snowline. These glaciers moves at a fairly slow rate, under the influence of gravity.
As the planet cools, the terminus of the glaciers (glacier end or toe) will expand and will be distributed more outward and downward, and there will be more quantity of snow in a cool planet.
The slightest change in pH can destroy the substance or organism. The pH of a cell's interior helps regulate the cell's chemical reactions. For example, the pH of blood is 7.4, if blood falls to 6.8 or lower or 8.2 or higher, it results in death.
