The sun's gravity would pull the earth in to it and the earth would burn up
The moon would spiral inward towards the Earth.
If the convection currents in the earth's mantle slowed down then the mantle would slow down. Eventually, the mantle would stop all movement.
If that were the only change, the seasons would simply be longer in duration, extending to about one quarter of the orbital period each.
Then our hours on day and night would be alot longer
Day and night happens because of the Earth turning around it's axis, and the seasons happen because of the Earth revolving around the sun.
the movement of the earth around the sun is caled what
The movement of the Earth in a month is actually a small portion of its orbit around the sun. One month on Earth is 1/12 of the Earth's orbit around the sun.
If the Earth's rotation slowed down, our we would have less gravity, and when we have less gravity we have things floating around for long nights and long days (also due to the planet slowing down). This can lead to many dis functions and could cause the appearance of anti-matter.

The seasons are caused by the tilt of the Earth's axis combined with its movement around the SUN.
