Halite

Halite is a type of rock that is made up of something called "sodium chloride," which is another name for common table salt. It usually looks really shiny and clear. People have been using halite for thousands of years to add flavor to their food and to preserve it for later so it doesn't go bad.

Halite is formed in different ways, but one of the most common is when salty water, like from the ocean or a lake, evaporates over time. As the water dries up, the salt in it stays behind and forms solid crystals that can eventually become a big chunk of halite rock.

Halite is important for many reasons. It's a valuable resource that's used in a lot of different industries, like making chemicals, treating roads in the winter to melt ice, and even as a type of medicine to help people with certain health problems. Plus, it tastes really good on popcorn!
