How is the Earth "slowing down"

I herd the Earth is slowing down...
Dose that meen the speed of its rotation is slowing? Is its orbit around the sun slowing? Or is it the speed of its wobble on the axis is slowing? or is it all 3?

Mostly the rotation rate is slowing down due to tidal friction with the moon - the day is getting longer and there will be fewer days in the year
The distance from the sun and so the length of the year is also increasing, but more slowly
