The Dead Sea is located in the Jordan Valley in southwest Asia. It is about 50 kilometres long and 15 kilometres wide at its widest point. It sits at about 430 metres below sea level, making it the lowest point on Earth's land.
What's interesting is that the Dead Sea isn't actually a sea. It's a lake with a salt concentration(含盐度) of more than 30 percent, which is about eight times saltier than typical seawater. This makes it one of the saltiest bodies of water on Earth.
The Dead Sea stays so salty due to its special natural conditions. Each year, it receives very little rainfall, and only a small amount of fresh water flows into it. And the hot weather around the Dead Sea causes the fresh water to evaporate(蒸发) quickly, which makes the salt concentration even higher. For these reasons, it is also known as the Salt Sea.
If you were to swim in the Dead Sea, you wouldn't see any sea life—no plants or animals. The high salt concentration makes it impossible for them to live there. That's actually why it's called the Dead Sea.
However, don't let the name or not having any sea life scare you. Even if you fall into the Dead Sea and can't swim, you won't die. The high concentration of salt in the Dead Sea allows anyone to float well, without the need for life buoys(救生圈). In fact, many people visit the Dead Sea every year on vacation. If you walk along the shore, you'll likely see many people floating in the water, reading books or magazines.
