The term "coastal regions" refers to areas that are located along a coastline, which is the area where land meets the sea. These regions can include beaches, cliffs, estuaries, lagoons and other geographical features that are influenced by the ocean. Coastal regions often have unique ecosystems, flora and fauna, as well as diverse human populations who rely on the coast for their livelihoods through fishing, tourism or agriculture. The climate in these areas is also affected by the proximity to water, which can result in milder temperatures and more precipitation than inland regions.
