Minerals formed as a result of evaporation in arid regions:

Arid regions are characterized by high temperatures and low precipitation. In such regions, water evaporates rapidly, leaving behind dissolved minerals. Over time, these minerals accumulate and form deposits. Some of the minerals that are formed as a result of evaporation in arid regions are:

Gypsum:
- Gypsum is a soft sulfate mineral that is widely used in construction as a building material.
- It is formed as a result of the evaporation of saline water in arid regions.
- As the water evaporates, the dissolved minerals become more concentrated, eventually leading to the formation of gypsum crystals.

Halite:
- Halite, also known as rock salt, is a mineral that is commonly found in arid regions.
- It is formed as a result of the evaporation of seawater or saltwater lakes in arid regions.
- As the water evaporates, the dissolved minerals become more concentrated, eventually leading to the formation of halite crystals.

Sylvite:
- Sylvite is a mineral that is commonly found in arid regions.
- It is formed as a result of the evaporation of brines in salt lakes and salt pans.
- As the water evaporates, the dissolved minerals become more concentrated, eventually leading to the formation of sylvite crystals.

Conclusion:
Out of the given options, only gypsum is formed as a result of evaporation in arid regions. Zinc, copper, and coal are not formed as a result of evaporation but are found in other geological formations.
