What is the difference between a brinicle and an evaporite?

• A brinicle is made of very cold and salty water, an evaporite is the salt formation left after water changes to the gas phase.

• A brinicle is made of very cold and salty water, an evaporite is the salt formation that evaporates into the air.

• A brinicle is a very dense and warm icicle of water in the arctic, and an evaporite is the salt formation left after water changes to the gas phase.

• A brinicle is a very dense and warm icicle of water in the arctic, and an evaporite is the salt formation that evaporates into the air.
