World age affects the prevalence of hills and mountains: younger worlds have larger, more craggy mountains that appear in bigger clusters whereas older worlds have more sloping hills that tend to appear in smaller clumps.
The code that governs this is in ContinentsPlus.lua:
local world_age_old = 2;
local world_age_normal = 3;
local world_age_new = 5;
-- Set values for hills and mountains according to World Age chosen by user.
local adjustment = world_age_normal;
if world_age == 3 then -- 5 Billion Years adjustment = world_age_old; adjust_plates = adjust_plates * 0.75;
elseif world_age == 1 then -- 3 Billion Years adjustment = world_age_new; adjust_plates = adjust_plates * 1.5;
else -- 4 Billion Years
end
-- Apply adjustment to hills and peaks settings.
local hillsBottom1 = 28 - adjustment;
local hillsTop1 = 28 + adjustment;
local hillsBottom2 = 72 - adjustment;
local hillsTop2 = 72 + adjustment;
local hillsClumps = 1 + adjustment;
local hillsNearMountains = 91 - (adjustment * 2) - extra_mountains;
local mountains = 97 - adjustment - extra_mountains;3 Billion= Lots of grasslands, few mountains and hills. 4 Billion= Stil some grasslands, an average amount of Mountains. And quite a few hills. 5 billion= Few grasslands. Lots of mountains. Tons of hills. Terrain: 3 Billion= Lots of plains, Lots of jungles and forests. 4 Billion= Some plains. Some deserts, and jungles, foresets and very little Tundra. 5 Billion= Few plains. Lots of desets, A few jungles and forests. And a lot of Tundra.
