Doldrum  is  the     region  of   very   calm  and  little or  no  wind  on  either side   of  the  equator. Doldrums  which  is  also  called  convergence  zone  is   an  equatorial  region  of  the  Atlantic  ocean  which  has  sudden  storms   and  light  unppredictable  winds.  In  addition  doldrum  is  abelt  around  the   earth  near   the  equator  where  the   sailing  ships  sometimes get  stuck  on  windless  water.
        
             
        
        
        
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.
        
                    
             
        
        
        
Answer:
Yes, the length of plate widening started from the poles and extends towards the other poles
Explanation:
- As the aspects of spherical geometry, the relative plate motion is affected by the rotation of the earth on its axis and not all are located at the geographic poles. As an example of mid-oceanic ridges that have a spreading value of 37-40 mm/year in southern Atlantic.
- Hene rotation of the poles can be determined by the accuracy an orientation of the mid-Atlantic ridges. Another example is of the African plate is moving to the east and the northern plate is moving to the west as template rotation is anticlockwise and paleomagnetism pole is and evident to this phenomenon.
- Spreading and splitting of the supercontinent like Pangaea created a major displacement in the orient rock and thus led by the rotation of the earth, this phenomenon also called the Euler pole and rotation angle based on the earth's orbit around the sun. 
 
        
             
        
        
        
Explanation:
When a destructive wave hits a coastline, it causes the washing away of the coastline and erosion of the beach fronts. 
When a constructive wave hits a coastline, new sediments are deposited there. 
Coastline is an area along the shore that straddles between the continent and the ocean. 
A destructive wave is a very high energy wave that moves materials from the coast in to the ocean. They cause the washing away of the ocean fronts. 
A constructive wave are usually of low energy. They bring materials landward more than towards the ocean.
