When electrons are removed from the outermost shell of calcium atom, its atom becomes positively charged, with a charge of plus one.
When an electron is added to an atom, the atom becomes negatively charged, with a charge of minus one.
When these atoms become positively or negatively charged, they are known as ions. Positively charged ions are called cations and negatively charged ions are called anions.
Calcium is identified as one of the cations because it is positively charged when its electrons are removed from its outermost shell.

B. the tilt of the Earth on it's axis
The moon affects the tides by it's gravitational pull on Earth. So the moon has no affect on the earth's seasons. The distance from earth from the sun only affects the ability of Earth to sustain liquid water because earth is in something scientists like to call the "Goldilocks Zone" This has no affect on the seasons. However, the angle at which the sun's light hit the earth does effect seasonal changes and it's tilt does change.
