Probably a good resource for your science class as he’s a geography professor and physicist and explains things simply/really easy to understand. He has heaps and heaps of videos explaining different subjects on youtube. 

Cretaceous Period: an Encyclopaedia Britannica article about all things cretaceous. Includes a large section on paleoclimate (good if your trying to figure out temperatures on your tropical world), marine and terrestrial life, as well as cretaceous geology. 

Links Between Loss of Sea Ice and Climate Change: a ScienceDaily article talking abt the period between 30-100,000 years ago and the abrupt climate change that happened during that period.

The Gulf Stream Explained: the whole youtube clip is animated and brightly coloured, it’s fun, go check it out.

Whimsy <--> Wild 

Whimsy 3 = Anything you could ever want is provided for you, all for the sake of enjoyment. Your existence is ruled by constant pleasure and stimulation.

Whimsy 2 = There is a constant quest for pleasure and stimulation, but there is no guarantee you’ll find it. Could be described as hedonistic. 

Whimsy 1 = Seeking joy is important, but it doesn’t consume you. Experiencing misery is unlikely.

Simple = Nothing is life threatening, but nothing is particularly pleasurable either. You are in a state of contentedness. 

Wild 1 = Danger is present, but you can protect yourself if you have the right resources.

Wild 2 = Your life is often threatened, and you have to be aware of your environment at all times. It’s often safer to stay in groups.

Wild 3 = You could die at any moment. The second you show weakness is the second you lose your life. Your existence is ruled by fear, hunger, and anxiety at all times.

Vitus <--> Mortis

Vitus 3 = Life predominates this world. There is no death or reproduction. Only eternity.

Vitus 2 = Denizens live very long lives, and nothing dies of old age. Disease and murder are nearly unheard of. However, while it may be difficult, it is possible for someone to die. 

Vitus 1 = Lifespans are long, but death is common. It is sometimes possible for Immortality to be attained.

Balanced = Everything lives, and everything dies. Death is inevitable and life marches on.

Mortis 1 = Death is inevitable, but not always permanent. Resurrection is a common art.

Mortis 2 = The living and dead coexist. Many types of undead populate this world. Even for the living, however, the line between life and death is blurred.

Mortis 3 = The Afterlife. Only the dead arrive, and no one leaves.

Linearity <--> Paradox

Linearity 3 = Time moves in on direction at a constant speed. It is impossible to go forward or go backward; only the present exists.

Linearity 2 = The past and future exist and can be seen, but nothing can be changed. “Destiny” is a popular concept.

Linearity 1 = Time is still a straight line, but it can be sped up or slowed down by multiple means. The past is concrete, but the future is malleable.

Stable = The timeline is stable and consistent; changes that happen are intentional.

Paradox 1 = Time often speeds up and slows down. The past can be changed. This can retcon the future, but it merely saves over the timeline.

Paradox 2 = The timeline splits constantly. Whether you stay in your original timeline or end up in a new one depends on the situation. Periods of time can sometimes repeat randomly.

Paradox 3 = Time has no meaning. It’s possible to be omnipresent at every second in this world’s existence. You will meet yourself often.

Rhyme <--> Reason

Rhyme 3 = Magic is the main construct of this world and can only be accomplished with sophisticated rhyming, alliteration, and wordplay.

Rhyme 2 = Magic is common and spells are developed using poetic devices. Other components may be necessary.

Rhyme 1 = Magic exists and can be accomplished with a mix of spoken spells and scientific practices or rituals.

Mundane = Magic is not believed to exist, and there are little to no unexplained or mysterious events to suggest otherwise.

Reason 1 =  Magic is not believed to exist, but there are some unexplained and mysterious events.

Reason 2 = Magic does not exist, but magic-like feats can be accomplished through advanced science, some of which may not be understood.
