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
