There is an interesting mystery in Death Valley National Park in the western U.S.
There are rocks that move!
Do you hear that? what a surprise news!
But around a hundred years after this phenomenon was first discovered, no one has ever seen them moved.
Somehow these rocks, many of which are as heavy as 700pounds,
move across the flat desert floor, leaving long trails behind them.
How do these rocks move?
Many people argue that wind is the prime mover.
Strong wind could get the process started.
Then lighter winds could keep the rocks rolling across the soft and slippery mud. Curves in the rock trails could be caused by shifts in wind direction.
Other people claims that winter ice moves the rocks.
It’s possible that water freezes around the rocks and then carries them along as the entire ice sheet melts and slides across the desert floor.
So are the rocks pushed by strong winds or carried by melting ice?
Both answers are scientific and correct.
Each one is partly responsible for the rock movement!
That is solved by Ralph Lorenz, a NASA scientist by constant research.
It’s funny
he announced, but there is some people expecting extraordinary still.
A reason is, to use Ralph Lorenz phrase,
‘Just people like mystery.’
I like that, too!
How about you? Which one are you agree?
Are you think more odd thing?
Just I said.. Enjoy your imagine!
It's interesting enough to wonder.
