1.	The time of one place differs from other. Give reason.
Answer» The biggest clock of the earth is the sun. The time of a place is decided by the location of the sun in the sky. However, to be precise, the time of the places on the earth is decided through longitudes. There are total 360 longitudes on the earth. The earth takes 24 hours to complete one rotation. Thus, in one hour, 15 longitudes (360/24 = 15) pass through the sun. In other way, it takes 4 minutes (60/15 = 4) for the earth to pass one longitude through the sun. This makes it clear that there is difference of 4 minutes between two adjacent longitudes. This time difference is used to decide the time of a particular place. According to this, the time at different longitudes is different at different places on the earth.
