Answer :
Answer:
1. Earthquakes and Eruptions (volcanoes)
2. Divergent plate boundary
3. Apart from a widening valley, it equally contributes to steep mountain sides spreading. A mid-oceanic ridge is naturally produced if two oceanic plates naturally start moving away from each other.
Explanation:
1. When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below. It responds by melting, and the new magma flows into the fissure. The magma then solidifies and the process repeats itself.
2. When two plate diverge from each other also known as divergent (di-apart, vergere- to inclined) plate margin .
Two plate diverge along oceanic ridges where new lithosphere is created.
Now come to the main point: Geological Features
When two oceanic plate diverge then new sea floor is created by a process called sea floor spreading and features like Mid oceanic ridges, volcanoes & Young lava flows forms. Ex. East Pacific Rise, Mid-Adlantic Ridge.
When two continental plates diverge by continental rifting then features like Rift valley, volcanoes are found. Ex of continent continent -East Africa rift vally, Red sea.
3. The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. ... If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.
