Answer 1

Hello Shruti :)

Your answer is

As we know that Liquids or Amorphous solids have a tendency to flow but sometimes it is called Pseudo Solids or Super Cooled Liquids. Now, Glasses are light bit thicker at the bottom compare to Top. Now this happens because glass flows down very slowly and makes the bottom part little bit thicker. This happens due to long exposure of light and dark due to day and night, causes heat difference which converts amorphous to some crystalline form and this makes the appearance of glass milky.
