The Department of Transportation, for example, requires that recipients of its funding award a percentage of contracts to minority-owned businesses and many large companies have goals for buying from minority-owned suppliers. The reason for such mandates is twofold.
A coastal zone is the interface between the land and water. These zones are important because a majority of the world's population inhabit such zones. The tidal bulges result in a rhythmic rise and fall of ocean surface, which is not noticeable to someone on a boat at sea, but is magnified along the coasts. 2  Usually there are two high tides and two low tides each day, and thus a variation in sea level as the tidal bulge passes through each point on the Earth's surface.
Rugged coastline of the West Coast Region of New Zealand. A coastline or a seashore is the area where land meets the sea or ocean, or a line that forms the boundary between the land and the ocean or a lake. A precise line that can be called a coastline cannot be determined due to the Coastline paradox.oth the terms coast and coastal are often used to describe a geographic location or region; for example, New Zealand's West Coast, or the East and West Coasts of the United States. A pelagic coast refers to a coast which fronts the open ocean, as opposed to a more sheltered coast in a gulf or bay.
