Answer:
Permafrost areas have very cold air temperatures, thin topsoil, and most water is frozen during the winter. ... Tundra is found at high latitudes and at high altitudes, where the permafrost has a very thin active layer. The active layer of tundra is too thin for trees to grow, because it cannot support a tree's roots.
Convection currents direct the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle.
In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading.
So, I would say the answer is:
As convection currents drift across the oceans,
they bring the pieces of Earth's crust with them as the supercontinent breaks apart.
Glad I could help, hv a good day :)
