to produce surfaces with higher degree of smoothness
Grinding quarts crystals down to produce sand is an example of decomposition.
What happens when sand or salt is used in place of the liver

Grinding quartz crystals down to produce sand is an example of physical change. When you grind quartz down to sand, you change the physical appearance of the quartz.
secret! para bibo! :))
Glycogen is extracted from animal tissue. This tissue is actually pretty tough and to liberate the glycogen from it, the tissue has to be ruptured, broken down nicely, so that all the glycogen is available for extraction. This grinding (homgenizing) process is aided by the presence of sand and TCA (Tri-Chloro Acetic acid). TCA is a higly corrosive agent and helps in rupturing the tissue.
Not all powders. Baby powder is talcum powder or corn starch, and baking powder is baking soda,salt,and starch. But, sulfur sand is usually in powder form.

Abrasion
It does happen. The UK recover quite a lot of the sand they need from the seabed. Otherwise, we may make a sand by grinding rocks to small sizes.
Jt is used for many things. Glass is made from silica. Sand is used in making concrete and mortar, and as an abrasive (grinding) agent.
