HOW OLD IS THE EARTH??

Bishop James Ussher 1581-1656

Used the Bible to estimate age of earth as approximately six thousand years

What is the current estimate for the age of the earth??a) 5 thousand yearsb) 5 million yearsc) 5 billion yearsd) 5 trillion years

What is the current estimate for the age of the earth??a) 5 thousand yearsb) 5 million yearsc) 5 billion yearsd) 5 trillion years(More precisely, about 4.6 billion years)

What does 4.6 billion really mean?? How far off was Bishop Usshers 6000 year estimate?Stack of 6000 pennies = 29 feet tall

Stack of 4.6 billion pennies = ???

What does 4.6 billion really mean?? How far off was Bishop Usshers 6000 year estimate?Stack of 6000 pennies = 29 feet tall

Stack of 4.6 billion pennies = 4200 MILES tall!!

What does 4.6 billion really mean?? How far off was Bishop Usshers 6000 year estimate?6000 dollars = $100 a day for 60 days

4.6 billion dollars = ???

What does 4.6 billion really mean?? How far off was Bishop Usshers 6000 year estimate?6000 dollars = $100 a day for 60 days

4.6 billion dollars = $100 per day for 126,000 YEARS!!

CONCLUSION:

THE EARTH IS VERY, VERY OLD!

This very long time allowslong-term, slow changes tohave major effects.For example:Tectonic plates move very slowly -about 2 centimeters per year.

In a billion years, a plate could move2 billion cm thats about 12,500 miles!!(halfway around the earth)

For example:Say a 10,000 foot high mountain loses 1/8 inch in height each year due to weathering.

In a MILLION years, 10,410 feet would have worn away - the mountain would be completely gone.

In a BILLION years, a mountain 1000 times as tall would be completely worn away!!

Next Timeline Activity to get a better idea of what was going on during this very, very long time.
