SOLAR SYSTEM

Detailed explanation-1: -Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

Detailed explanation-2: -Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.

Detailed explanation-3: -At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.

Detailed explanation-4: -Mid-oceanic ridges are formed along with two diverging oceanic plates. As two oceanic plates diverge, magma comes out and eventually solidifies leading to the formation of mid-oceanic ridges.

Detailed explanation-5: -Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).

Detailed explanation-6: -Divergent plate boundaries in the ocean create mid-ocean ridges. This is where new seafloor is created by upwelling magma. Divergent plate boundaries rift a continent apart. Eventually a new ocean will form between the two continents. Iceland is a location where we can see a mid-ocean ridge above sea level.
