Answer:
White dwarfs have an extremely small surface area to radiate this heat from, so they cool gradually, remaining hot for a long time.
Explanation:
As a white dwarf cools, its surface temperature decreases, the radiation which it emits reddens, and its luminosity decreases.
When the ground subsides it can become lower than the surrounding terrain, forming a basin.
Since water, which carries sediment, flows downhill, sediment will collects in these basins.
If enough sediment collects, compaction and cementation will turn it into sedimentary rock.
