What kind of vegetation is most common to the east of the caspian sea?

temperate grassland and deciduous and mixed forest

Explanation:

The Caspian Sea is the largest lake on Planet Earth, with an area of approximately 371,000 km², being about 1200 km long and 450 km wide. Despite being a lake, its brackish water and its enormous size, led the Caspian to be considered a sea by the people of Antiquity. However, its brackish water is due to the fact that the Caspian is located in the Caspian Depression, a region in Central Asia where the region's drainage basins converge.

To the east of the Caspian Sea, temperate grassland and deciduous and mixed forest vegetation predominates.
