Define the following terms: • Coastal plain estuary • Tectonic estuary • Fjord

What will be an ideal response?


A coastal plain estuary is formed between glacial periods when water from melting glaciers causes the sea level to rise and flood coastal plains and low-lying rivers. A tectonic estuary is created when earthquakes cause the land to sink, allowing seawater to cover it. A fjord is a glacial cut deep valley filled with water.
