Answer 2

HEY MATE....

Such a cool question....

here's your answer......

If everyone on Earth jumped at Once.....

* There would be a huge sound like an applause.
*
The ground would begin to shake, and if the jump happened near the coast, it could trigger a tsunami with 100-feet-tall waves.
The shaking could also lead to an earthquake falling in the 4-8 magnitude range. That means it could be anywhere from a light shake to one that could cause some major destruction to bridges, railways, electric lines, and buildings.
