Continental Margins

Continental margins are the edges of continents where they meet the ocean. These areas include both the visible parts of the continent and the sections that extend underwater, gradually blending into the ocean floor. There are two main types of continental margins: active and passive.

Active margins occur where tectonic plates meet or collide, resulting in significant geological activity, such as earthquakes, volcanoes, and mountain formation.

A well-known example of an active margin is the west coast of North America, including California. This region lies at the boundary of the Pacific Plate and the North American Plate. The interaction between these plates causes frequent earthquakes, volcanic activity, and the creation of rugged landscapes, such as cliffs and mountains.

In contrast, passive margins are located far from tectonic plate boundaries. Here, the land transitions gently into the ocean with minimal geological activity.

The east coast of the United States, including Florida, is an excellent example of a passive margin. This area is characterized by flat, sandy beaches like those in Daytona Beach.
