The terms boundary, frontier and border are often used as if they were interchangeable, but they are also terms with precise meanings. [6] A boundary is a line. The terms "frontier", "borderland" and "border" are zones of indeterminate width. Such areas form the outermost part of a country. Borders are bounded on one side by a national boundary ...
Normally, the baseline is the low-water line along the coast as marked on large-scale charts that the coastal state recognizes. This is either the low-water mark closest to the shore or an unlimited distance from permanently exposed land, provided that some portion of elevations exposed at low tide but covered at high tide (such as mud flats) is within 3 nautical miles (5.6 kilometres; 3 + 1 ...
A line wavy (also called undy) [12] is a sine wave, often used to represent water; a line nebuly is similar but with more exaggerated meanders, representing clouds. There are confusing, ambiguous and non-standard uses of a wavy in the military heraldry of the United States to refer to irregularly wavy lines.
The littoral zone, also called litoral or nearshore, is the part of a sea, lake, or river that is close to the shore. [1] In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the foreshore — and the terms are often used interchangeably.
The fluid particles cling to the hull of the ship due to the adhesive force between water and the ship, creating a boundary layer where the speed of flow of the fluid forms a small but steep speed gradient, with the fluid in contact with the ship ideally has a relative velocity of 0, and the fluid at the border of the boundary layer being the ...
The amount of forest edge is orders of magnitude greater now in the United States than when the Europeans first began settling North America. Some species have benefited from this fact, for example, the brown-headed cowbird , which is a brood parasite that lays its eggs in the nests of songbirds nesting in forest near the forest boundary.

Cape Agulhas is located in the Overberg region, 170 kilometres (105 mi) southeast of Cape Town.The cape was named by Portuguese navigators, who called it Cabo das Agulhas—Portuguese for "Cape of Needles"—after noticing that around the year 1500 the direction of magnetic north (and therefore the compass needle) coincided with true north in the region.

Fig. 5 & 6 show the edges of forests or banks treated in such a way as to lengthen the ecotone considerably without excessively modifying the environment. Fig.7 shows a common interpenetration of media (such as that found at the edge of a forest). Fig.8 shows an ecotone that could have been formed by an animal modifying its environment.
