Selection centres are used by graduate employers who need to assess a large group of potential graduate recruits. Instead of interviewing each candidate individually, a selection centre allows an employer to see groups of candidates taking part in tasks and role-plays. In theory, this makes selection centres a fairer method of recruitment than an interview.
Over very long time periods (thousands of years) the direction of Earth's axis slowly changes due to precession. The Earth rotates around once in 24 hours-that's a rate of 1000 miles per hour!. The time it takes for the Earth to rotate completely around once is what we call a day. It's Earth's rotation that gives us night and day. The combined effect of the Earth's tilt and its orbital motion result in the seasons.
How Long Does It Take the Earth to Make One Rotation on Its Axis? Tweet It actually takes the Earth 23 hours, 56 minutes and 4.06 seconds to make one rotation on its axis, not 24 hours.
