Why is the Great Salt Lake salty?


assistant
The Great Salt Lake is salty because water only flows into the lake, not out. This is called a “terminal lake.” Over time, the water in the lake evaporates, leaving behind the minerals that flowed in with the water. Because the amount of water in the lake remains relatively constant but the amount of minerals increases over time, the lake becomes more salty over time.
