Question

question: which of the following is/are made from melted quartz sand?
answer options:
select one of four
mineral halites
ceramics
glass
clay minerals

Explanation:

To determine which is made from melted quartz sand, we analyze each option:

• Mineral halites (rock salt) form from evaporation, not melted quartz sand.
• Ceramics are made from clay (aluminum - silicate minerals) fired, not melted quartz sand.
• Glass is produced by melting quartz sand (silica, $SiO_2$) and other additives.
• Clay minerals are formed from weathering of rocks, not from melted quartz sand.

Answer:

Glass
