Unsurprisingly among scientists, continents and ocean floors are in continuous motion. This movement occurs through magmatic currents in the innermost layers of the Earth (convection currents), which eventually alter the position of the immense blocks of rock floating above the magma, called tectonic plates.
Thus, this movement of the plates eventually leads to constant shocks in their meeting regions, which causes seismic and volcanic activities around the globe. The boundaries between such tectonic plates, however, may follow different orientations.
Divergent Limits: In this type of limit, there is the separation between plates. In the space created between the two large blocks, the formation of a new crust occurs through the solidification of the magma. It can occur on continents or oceans.
Divergent boundary in the oceans: When this type of boundary occurs in oceans, there is the creation of gigantic submerged ridges, known as dorsal oceanic. The most famous of these is the mesoatlantic dorsal, which occurs at the boundary between the North American and Eurasian plates and extends across the South American and African plates, cutting a portion of the globe from the Arctic to southern Africa.
Divergent boundaries such as the mid-oceanic ridge system.
Explanation:
Divergent boundaries occur when plate boundaries pull away from each other. Molten rock or magma rise from the gap between the two plates, rising up to the sea floor where it cools down to form new crust. It is the mid-ocean ridges where you see the most magma produced and there has not been any other tectonic event or area that could match its procution since the Precambrian period.
The radiation fog is formed when the land surface cools after the sunset in the conditions of the clear sky. Thus the cooling ground cools the air above it and as a result of this the conduction causes the air temperature to fall and hence it reaches the dew point and forms a fog.
