Final answer:
Examples of earth-filled barriers include levees, berms, and earthen dams, which serve to prevent flooding, provide defense, and manage water supply.
Step-by-step explanation:
Earth-filled barriers are significant structures that are created using the soil and rocks from the Earth to form protection or delineation of certain areas. Examples of earth-filled barriers include levees, berms, and earthen dams. These structures serve various purposes like flood control, military defense, and agricultural uses. Levees are typically constructed alongside rivers to prevent flooding by creating a barrier between the water and the land. Berms are raised barriers often used in gardens, construction sites, or around fortified structures. Lastly, earthen dams are built to hold back water in reservoirs, playing a critical role in water management and supply.
In the context of historical structures, the Great Wall of China is an ancient example that was partly constructed with rammed earth, utilizing layers of compacted soil to create a formidable defense system. Additionally, barrier islands serve as natural earth-filled barriers, protecting the coastline from the harsh impacts of oceanic forces.
