Which of the following is not true?
a. The earth's axis is tilted 23.5 degrees relative to the plane of the ecliptic.
b. The axis through earth's two poles points just slightly off polaris
c. During the winter months, the earth's axis is aligned towards southern cross
d. Throughout the year, the Earth's axis maintains the same alignment relative to the plane of the ecliptic
We have seasons because Earth's axis – the imaginary line that goes through the Earth and around which the Earth spins — is tilted. It's tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun.
