when you hear the name of the dead sea, it might not sound like a lively place. and in fact, it was given its gloomy name for a good reason. it is different from other seas due to the fact that it’s extremely salty. the main reason for this is that it’s completely surrounded by land. so water that flows into it is trapped there until it evaporates. when it does, it leaves behind salty minerals, causing the sea to become saltier and saltier. actually, more than 30 different kinds of mineral salts are found in the dead sea, including potassium, bromine and magnesium. because of this, nearly any creature that enters it dies a short time later. only certain microbes are able to survive — the water is too salty for anything else to live in it.
