What is the coast? In layman's terms, the coast is the part of the land that is adjacent to the sea. Furthermore, the coast is the narrow area of land above the coastline.
In short, the coast is the most beautiful scenery between the land and the sea, which separates the land and the sea and connects the land and the sea. However, it is not a fixed dividing line between the ocean and the land, but a zone that changes every day due to factors such as tides and shoreline waves seen from the air.
Schematic diagram of the evolution of the coast
The coast was formed in distant geological times. When the earth was formed and the ocean appeared, the coast was born. The winding coastline has gone through the vicissitudes of the honeycomb rocks formed by waves eroding along the Fujian coast to become what it is today.
The coastal landforms are diverse and the types of coasts are diverse. Standing on the coast and looking at the vast and turbulent ocean, anyone will be amazed by the majestic landscape. Sail along the coast to see the coast, which is even more spectacular.
Bird's eye view of the coast
The coast is also an important area for human reproduction, life, labor, and production. Since the beginning of mankind, people have continuously developed coasts, making human footprints all over the world's coasts.

In modern society, more than half of the world's population lives near the coast, creating more than 60% of material wealth. Hundreds of millions of people live in coastal areas and depend on the coast. The beautiful and rich coast has enabled hundreds of millions of people and coastal countries and regions to move from poverty and backwardness to wealth and prosperity.
The changing coast has gone through vicissitudes of life, as if everything has become a distant past. However, through the paleontological fossils and traces of erosion and accumulation left by the ocean and land, people have found clues to the ancient coastline. Along these traces, whether they are hanging high or buried deep underground, we will see the coastline. We will unravel the mysteries of the vicissitudes of the coast one by one, scientifically and accurately tell the changes of the coast yesterday, and foresee the future of the coast.
When people think of the coast, they think of cliffs and beaches, of splashing white foam, crashing waves, and of the spectacular sight of a red sun rising from the indigo sea.
According to coastal dynamics, it can be divided into accumulation coast and erosive coast. According to geological structure, it can be divided into ascending coast and descending coast. According to the properties of coastal materials, coast can be divided into bedrock coast, gravel coast, plain coast and mangrove coast. and coral reef coast.
