  • time and the Earth

  • what time is it that's a very good question from morning until night clocks

  • help us to plan our day they tell us when things begin and when they end

  • before clocks people told Time by watching the sun move across the sky

  • they started work when the sun came up in the east at noon when the sun was

  • very high they ate and rested when the sun disappeared in the west they went to bed

  • today we know that the sun doesn't move around the earth the Earth turns or

  • spins on an imaginary line called an axis as the Earth turns the sun seems to be

  • moving across the sky the time it takes for the earth to make

  • one complete turn is called a day a day is divided into hours minutes and seconds

  • there are 24 hours in a day there are 60 minutes in an hour

  • how many minutes are there in a day multiply 24 hours times 60 minutes to

  • get the answer 24 times 60 equals 1440.

  • there are 1440 minutes in one day we measure Time by other movements too

  • the Earth travels around or orbits the Sun the time it takes for the earth to go

  • around the Sun once is called a year one year is equal to 12 months or

  • just over 52 weeks to be very accurate it takes the earth

  • 365 days 5 hours 49 minutes and 12 seconds to go around the Sun

  • we divide the earth into 24 time zones each time zone is one hour apart from

  • the next time zone for example when it is 10 AM where you live it is 10 pm on

  • the opposite side of the world in two hours it will be noon where you

  • live but on the other side of the world it will be 12 at night

  • thanks to clocks and calendars we can measure time very easily however it is

  • the movement of the earth that really allows us to measure tim
