What are the movements of the Earth based upon the perceived changes in positions of the stars?
The "sidereal day" and the "sidereal year". The sidereal day is the time taken for Earth to rotate once, measured against the background of stars. Stars are very distant, so it means we get an accurate measure of the rotation time. The day of 24 hours is based on Earth's rotation relative to the Sun. That doesn't give the "true" rotation time, but it's very convenient in daily life, of course.
What time is mid-day sidereal time in the UK?

Why do we use the mean solar day rather then the sidereal day to measure the time for one earth rotation?
We don't. The sidereal day IS used as the measure of the Earth's rotation. The mean solar day is used to regulate our daily lives because that's the average time for the Sun to complete its apparent daily journey round the sky. The difference is because the solar day takes into account the effect of the Earth's orbital motion which slightly alters the position of the Sun in the sky.
What is the difference between a sidereal month and and a synodic month?
A sidereal month is the time it takes the moon to complete one orbit of earth. A synodic month is longer than a sidereal month because it takes longer for the moon to go through it's phases
What is the time that take earth to rotate on its axis called?
