A bomb cyclone is basically a storm that can rival the strength of a hurricane. They're called bomb cyclones or "weather bombs" because of the process that creates them (bombogenesis) basically bombogenesis is a storm that undergoes rapid strengthening.
The word bombogenesis comes from two words: bomb and cyclogenesis. All storms are cyclones and genesis means the creation or beginning and in this case bomb means explosive development so all together it means explosive storm strengthening
Bomb cyclones happen more in winter months and can carry hurricane force winds, cause coastal flooding and HEAVY snow. Bomb cyclones happen when a quickly forming storm results in a drop in atmospheric pressure of at least 24 millibars.
Basically its like a hurricane but stronger sometimes. The wind and flooding make it more like a hurricane but the blizzards and snow make it stronger

The convection currents are the ones that create the force that breaks up and moves the crustal plates on the surface of the planet. By moving the crustal plates, the convection currents contribute to the formation of different types of plate boundaries, including the divergent plate boundaries.
The divergent plate boundaries are the boundaries where two plates are moving away from one another because the convection currents are dictating that kind of movement from bellow them. As they move away from each other, they leave a gap between them, and the convection currents push up a lot of magma towards the surface. The magma cools of very quickly in the water, thus forming rocks constantly, rocks that little by little start to make a big mas, that eventually turns into an underwater mountain, or rather a mid-ocean ridge.
