Qukoha is a dynamic planet. Much of the time the weather is temperate on a large part of the land masses. However, the planet experiences intense cold periods cyclically when the comet Istuss passes through the Kisc star system. Qukoha has a strong magnetic field caused by the large amount of iron at its core. The composition of the comet is unknown, but it also has a strong magnetic field. The comet passes through the Kisc star system approximately every 100,000,000 years. The interaction of the magnetic fields of the comet and Qukoha tilts the axis of Qukoha 4 to 5 degrees further toward the sun. This causes a sudden climate change over about a two year period that freezes many of the temperate areas of the planet. Due to magnetic forces of the other planets in the system, Qukoha slowly returns to a 21 degree tilt in approximately 50,000,000 years and spends the next 50,000,000 years at this angle until the comet cycles past again. Species of life able to withstand the cold have survived for several million years on the planet. Some interesting adaptations have occurred among the species preferring warmer climates and many warmer species have died off each time the comet visits.
Qukoha's land masses have interesting animal and plant migration routes. The two large continents that extend from the North and South poles nearly touch on one side of the planet. There is a string of islands that almost form a bridge between the two continents. Many plants and animals have spread all over these two continents. Additionally, ocean currents flow from North to South on one side of the islands and from South to North on the other side of the islands, aiding the transfer of living beings between the two continents. Further many cold thriving species live near the polar ice caps and have migrated to the warmer climates. During the cold periods these cold thriving species have been better suited to survive climate changes by migrating to warmer areas or simply by adapting to the cold. The warm thriving species have tended to die off, with a few finding successful adaptations.
The third continent on the planet is isolated
in the ocean. It is in the warmer part of the planet and has had
fewer cold resistant species living on it and thus has had more
turnover of species during the cold periods.
