Let’s get closer to the Dead Sea and learn more about it. The Dead Sea is located in Southwest Asia. It is about 50 kilometers long and 15 kilometers wide at its widest point. It sits at about 430 meters 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. The salt concentration (盐浓度) in it is 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 because of its special natural conditions. Each year, it receives very little rainfall, and only a small amount of freshwater flows into it. And the hot weather around the Dead Sea causes the freshwater 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 are to swim in the Dead Sea, you won’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 lakeside, you’ll likely see many people floating in the water, reading books or magazines. 1．What do we know about the Dead Sea? A．It is the largest place in Asia.
