They are called fringing reefs. They grow directly from shore and form borders along the shoreline.
When a fringing reef continues to grow upward from a volcanic island that has sunk entirely below the sea level, an atoll is formed. Atolls are usually circular or oval in shape, with an open lagoon in the center.
The fringing reef is the most common type of coral reef. They however tend to be very sensitive to human induced pollution in the water and are easily destroyed by such.
Poland has been Catholic for a long while and since the Church is an ecclesiestical institution, it plays no big role in trade. The Soviet Union had a very protective attitude towards its products and only a few categories of them were exported; it is quite possible that exports dropped during this period. THe Warsaw Pact marked a significant counterpoint to the NATO initiative but most countries were already good trade partners to the Soviet Union (and again, the pact was not about trade). The right answer is European Union; the open borders and the influx of technology has increased the potential for exports from Poland.
