No. The leap year happens because it actually takes the Earth 365 and a quarter days to go round the sun. The quarter days are ignored most of the time but to stop the calendar going out of sync, an extra day is added every 4 years so everything adds up. The tilt of the Earth causes the change of the seasons.
what causes all of the changes that take place in earths atmosphere is the tilt of the earths axis
These happen because the axis of Earths spin in inclined at an angle from the normal of to the plane in which it orbits the Sun.

Climate
Earth's tilting on its axis leads to seasonal changes due variations in the angle (rather than distance) at which light hits.
Because it tilts on its axis
because of the earths axis
They differ from the earths axis in relationship to its position during its one year revolution.
the tilt of the earths axis.
Because Earths axis is tilted.
Earth's climates might be different because they won't be the same
Because there is no physical axis. That's just the imaginary line around which the Earth rotates.
