Answer 4

I know all about the rotation and revolution but I am mainly confused about the summer and winter solstices..

Answer 5

Sol means sun and stice means standing still. Until 21 June or so, the days get longer and the sun is higher in the sky each midday. After 21 June or so, the days get shorter and the sun is lower in the sky each midday. So it looks like the sun stopped moving North at the summer solstice.
The reason this occurs is another story.
________

the only reason that this happens is that the earth is tilted to it's axis while it is revolving around the sun.

if the earth is perpendicular to it's axis in relation to the sun, then there would never be summer or winter soltices.
