in scan line polygon fill, each can line crossing a polygon, the area fill algorithm locates the intersection point of the scan line with the polygon edges. These intersection points are then stored from left to right and the corresponding frame buffer positions between each intersection painr are set to the specified fill color.
In boundary fill, approach to area filling is to start at a point inside a region and paint the interior outward toward and the boundary.
Advantages : - very simple - efficiency and correctness Disadvantages : - requires getpixel() system call - not efficient for large polygons - needs a large stack - requires a seed point

boundary fill fills boundary with one color and flood fill fills boundary with different color.
boundaryfill fills area till the single boundary color is reached whereas floodfill fills area not defined by single boundary colourfloodfill replaces interior colour instead of searching for boundary colour

A divergent boundary occurs when two tectonic plates move away from each other, creating new crust as magma rises to fill the gap.
The Mid-Atlantic Ridge is formed where the Eurasian Plate and the North American Plate are diverging, creating a boundary known as a divergent plate boundary. As the plates move apart, magma rises from the mantle to fill the gap, creating new oceanic crust.
When plates move apart from each other in opposite directions, it is known as a divergent boundary. This movement creates new oceanic crust as magma rises to fill the gap created by the separating plates. Volcanic activity and earthquakes are common at divergent boundaries.

A mid-ocean ridge is formed in a divergent boundary where two tectonic plates move away from each other. Magma rises to fill the gap created by the plates moving apart, creating new oceanic crust. This process results in a continuous mountain range on the ocean floor.
A mid-ocean ridge forms at the divergent plate boundary. This boundary initially forms rifts that later on become rift valleys.
A divergent plate boundary is where two tectonic plates move away from each other. As they separate, magma from the mantle rises to fill the gap, solidifying to form new crust. This process is known as seafloor spreading.
