Which variable of the Milankovitch Cycles is most responsible for the different seasons on Earth?
eccentricity (the shape of Earth's orbit)
obliquity (the tilt of Earth's axis)

hotter summers and colder winters
cold summer and cold winters
extreme summers and extreme winters
What is the difference between weather and climate?
They are the same.
Weather is day to day, while climate is observed over a long periods.
Climate is day to day, while weather is observed over a long period.
Weather changes, while climate does not.
When the orbit is more oval (elliptical) there is a bigger difference in earth-sun distance. This refers to...
eccentricty
obliquity
precession
The change in orbital shape results in more or less sunlight reaching the Earth (the whole earth).
eccentricity
obliquity
precession
This cycle will be responsible for swapping the North Star (now called "Polaris") with another star.
eccentricity
obliquity
precession
