Final answer:
The rise in sea levels during the Middle Jurassic period caused the formation of inland seas and expansion of deserts.
Step-by-step explanation:
The rise in sea levels during the Middle Jurassic period had an impact on global geography. One of the major effects was the formation of inland seas. As the sea levels rose, low-lying areas were flooded, creating shallow seas that covered parts of continents. These inland seas provided new habitats for marine organisms and influenced the distribution of land animals.
Another impact of the rising sea levels was the expansion of deserts. As the sea levels rose, moisture was drawn away from the land, causing previously fertile areas to become arid. This led to the formation or expansion of deserts.
The rise in sea levels during the Middle Jurassic period did not result in increased mountain formations or ice age conditions. The changes in sea levels primarily affected coastal and low-lying areas, rather than mountainous regions or polar regions.
