Estuaries are present along both Coastlines, but the ones along submergent coastlines are much larger in size. Estuaries represent the flooded, lower portions of stream and river valleys. Since sea level has been rising steadily, large estuaries and estuarine systems have developed along tectonically stable continental margins with wide continental shelves and coastal plains; the Atlantic and Gulf coasts of the United States are good examples. Along wide coastal plains, each incremental rise in sea level inundates much larger areas than along tectonically rising coasts where elevations and relief are higher and stream valleys are more likely to be steep-sided and narrow.
Submergent coasts are formed when sea levels rise or land sinks, leading to the flooding of coastal areas and the creation of features like estuaries and drowned river valleys. In contrast, emergent coasts occur when land rises relative to sea level or when sea levels fall, resulting in features such as cliffs and elevated terraces. Essentially, submergent coasts are characterized by submersion and inundation, while emergent coasts are marked by exposure and elevation.
Emergent coasts are formed when the land rises relative to sea level. This can happen due to tectonic uplift, isostatic rebound, or a decrease in sea level. The uplifted land creates a coastline that is gradually exposed to the sea, causing the formation of emergent features such as elevated cliffs, terraces, and raised beaches.
Prawns can be found near the seafloor of most coasts and estuaries. They may also be found in rivers and lakes.
Flounder are saltwater fish that live in lagoons and estuaries. Flounder species are found along the Atlantic coasts of the US and Canada, in Europe, and in Japan.
Coasts exist at the interface between land and bodies of water, such as oceans, seas, and large lakes. They can be found along continents and islands, characterized by various geographical features like beaches, cliffs, and estuaries. Coasts are dynamic environments influenced by factors like tides, waves, and human activities, and they play a crucial role in ecosystems and human settlements.

Tidal ranges are typically largest on coasts with funnel-shaped bays or estuaries that amplify the tide. Additionally, coasts with narrow channels, shallow depths, and a resonant natural period that matches the tide-generating forces can also experience significant tidal ranges.

Coasts vary significantly in size and characteristics, depending on factors like geography, climate, and local ecosystems. They can range from just a few meters wide in some urban areas to several kilometers in more natural settings such as estuaries or wetlands. Globally, coastlines stretch for over 1.2 million kilometers, with diverse features including sandy beaches, rocky cliffs, and marshlands. Overall, the size of coasts is highly variable and influenced by both natural processes and human activities.

Yes, lowlands are found along both the Atlantic and Gulf coasts of the United States. These coastal plains are characterized by flat, low-lying terrain and are often prone to flooding. The Atlantic Coastal Plain extends from New Jersey to Florida, while the Gulf Coastal Plain stretches from Texas to Florida. Both regions feature wetlands, marshes, and estuaries, contributing to their unique ecosystems.
