My planet also has a very large percentage of ocean coverage, altho I'm
not sure just how much yet. It has no mountain ranges, and only a few
hilly regions. It's been geologically dead for hundreds of millions of
years, so mountains have eroded away by now. It's also much hotter than
our world. As a consequence, there are no ice caps, and there is much
more evaporation from the oceans, and, consequently, much more
precipitation as well. Massive river systems are commonplace. The
closest equivalent it has to mountains is on the Far Continent where, 20
million years ago, several pieces of an asteroid collided with the
planet, creating large craters with high walls. The interior of these
craters are now lakes.

My planet has a lot more tropical storms and hurricanes than ours, due
to the greater temperatures.
The planet also has a higher level of oxygen, which would create a
problem for Earth life, as they'd tend to burn away every few months.
:-) Native plant life has developed resistance to fire. The evolution
of such resistance hundreds of millions of years ago lead to the
planet's first ice age. Previously, plants had been fast growing, fast
reproducing, and short-lived, being subject to frequent wide-spread
fires. (In fact, some theorize that there may have been never-ending
fires, fires that would sweep across continents, and then return to
where it started, by which time life had already returned to the
ashes!) These first fire-resistant plants preserved the rapid growth
and reproduction, and lead to huge overgrowth, tangled jungles,
fast-growing accumulations of undecayed material, being covered over
faster than they could decay, leading to the evolution of carnivorous
plants as nutrients became scarce. Carbon dioxide was removed from the
atmosphere much faster than it was replaced, leading to an ice age which
resulted in mass extinction, and also huge deposits of fossil fuels :-)
The plants that survived the ice age were slower growing. Nowadays,
fire is rare. And when it does occur, tends to be limited to forest
