Two similarities between the Caspian Sea and the Aral Sea are:

1. Both are located in Central Asia: The Caspian Sea is situated between Europe and Asia, bordering five countries: Russia, Kazakhstan, Turkmenistan, Iran, and Azerbaijan. The Aral Sea is located between Kazakhstan and Uzbekistan.

2. Both are saltwater bodies: The Caspian Sea is the largest enclosed inland body of water on Earth and is the world's largest salt lake. It has a higher salinity compared to the ocean. Similarly, the Aral Sea was once the fourth largest lake globally and had a saline character due to its limited connection with other water bodies. However, due to human activity, the Aral Sea has significantly shrunk, resulting in increased salinity.
