No natural barrier completely protected Egypt from invasion as all of these difficulties were eventually overcome, but some of the natural barriers that substantially minimized foreign invasions were: the Sahara Desert, the Red Sea, the Sinai Desert, and the Mediterranean Sea. (Amphibious assaults were usually not terribly successful at this period.)
The endothelial cells of the blood-brain barrier house the mechanisms that most often interact with substances that cross the barrier. These cells feature specialized tight junctions that regulate the passage of molecules into the brain. Astrocytes also play a role in supporting these endothelial cells and maintaining the integrity of the blood-brain barrier.
A feature that forms as a result of the growth of a spit is a barrier beach. As the spit extends out into the water, it can enclose a lagoon or estuary behind it, creating a sheltered area. This process is driven by sediment deposition and longshore drift, which contribute to the spit’s elongation. Over time, the barrier beach can further influence coastal ecosystems and sediment dynamics in the area.
St. Simons and Tybee are examples of barrier islands, which are coastal landforms that run parallel to the mainland. These islands are typically characterized by sandy beaches, dunes, and salt marshes, providing important habitats and recreational areas. They serve as natural buffers against storms and coastal erosion.

The Great Wall of China served as a natural protection for northern China, as it acted as a barrier against invading forces. Additionally, the Gobi Desert to the north provided a natural obstacle that deterred potential invaders.
The Appalachian Mountains are to the west of the 13 colonies. They stretch from Maine to Georgia and were a significant geographical feature for the colonial settlers, acting as a natural barrier to westward expansion.
