The seafloor spreading occurs at the mid-ocean ridges. The reason for this is that the convection currents from the mantle manage to break through the oceanic crust and propel magma on the seafloor. As they do, the magma consolidated in the water and new crust is created. Since there's constant pilling up of new crust, it pushes the old crust away in both sides. This results in the movement of the plates, and as they move eventually they will come into a situation to collide, resulting in the continents to start merging with one another. As the continental masses merge, they will gradually create a supercontinent.

The correct answer is - A. polar.
The perpetual night appears only on the north pole and the south pole and their closest surrounding areas. This is due to the Earth's inclination which makes it possible for this phenomenon to appear, because of the way the Earth is inclined and positioned towards the Sun throughout the year we have situations when for half of the year one of the poles is not getting any sunlight, while in the other half of the year the other pole is not getting any sunlight. When one of the poles experiences perpetual night, the other experiences a perpetual day.
