The method for obtaining salt from the ocean is a fascinating natural process, assisted by human effort. This process, known as solar evaporation, is most effective in coastal regions with hot, dry climates and low rainfall.

The first step is to channel seawater into a series of large, shallow ponds. These large ponds are also known as salt pans. They are designed to be shallow so that a larger surface area of water is exposed to the sun and wind, which speeds up the evaporation process. The water is then moved from one pond to another as it becomes saltier.

As the water sits in these pans under the hot sun, it slowly begins to disappear into the air. The water level drops (21) __________ the sun and wind cause evaporation, leaving behind a highly concentrated saltwater solution. This is the most crucial stage, as it relies entirely on the right weather conditions to be successful.

Once most of the water has evaporated, salt crystals begin to form. This process involves (22) __________ large piles of salt which are then raked and collected by workers.

The entire system is a beautiful example of using nature's own power to produce a valuable resource. If the climate were not hot and dry, this entire process (24) __________ possible. It shows a simple yet effective way humans have worked with the environment for centuries.
