Q: What is a soda lake?
A: A soda lake is an alkaline salt lake with a high content of carbonate.
Q: How are salt lakes categorized based on salinity?
A: Salt lakes are categorized based on salinity into subsaline 0.5–3 ‰ (parts per thousand), hyposaline 3–20 ‰, mesosaline 20–50 ‰, and hypersaline greater than 50 ‰.
Q: How do salt lakes form?
A: Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave, and the water then evaporates, leaving behind any dissolved salts, increasing its salinity.
Q: What is the importance of salt lakes?
A: Salt lakes are an excellent place for salt production and high salinity leads to a unique flora and fauna in the lake.
Q: What happens if the amount of water flowing into a salt lake is less than the amount evaporated?
A: If the amount of water flowing into a salt lake is less than the amount evaporated, the lake will eventually disappear and leave a dry lake: a 'playa', salt flat or salt pan.
