What would happen if a large asteroid hit the moon?
If the 400-meter-wide asteroid were to impact the moon, it would kick up enough dust — and that dust would moving at a high enough speed — for a small quantity to escape the moon’s gravity and coast all the way to Earth, 240,000 miles away, Yeomans said..
What happens if the moon is destroyed?
Destroying the Moon would send debris to Earth, but it might not be life-exterminating. … If the blast were weak enough, the debris would re-form into one or more new moons; if it were too strong, there would be nothing left; of just the right magnitude, and it would create a ringed system around Earth.
What would happen if the Earth slowly stopped spinning?
If the Earth gradually slowed, the bulging water from the oceans would begin to move away from the equator towards the poles. Once Earth stopped spinning completely, leaving it as a sphere, the oceans would flood most of Earth leaving one giant megacontinent around the middle of the planet.
Would gravity increase if the earth stopped spinning?
Gravity is caused by the mass of the earth, not its rotation, so there would be no effect on gravity if the earth stopped spinning. There would be a slight change to the weight of objects though. The rotation of the earth has a small centrifugal effect on objects.
Can we live without sun?
Without the sun there would be no vegetation on earth, because every plant needs light to live and grow. The sun even enables them to generate oxygen by means of photosynthesis, which humans and animals need to breathe.
Why does the moon not spin?
A changing orbit. Gravity from Earth pulls on the closest tidal bulge, trying to keep it aligned. This creates tidal friction that slows the moon’s rotation. Over time, the rotation was slowed enough that the moon’s orbit and rotation matched, and the same face became tidally locked, forever pointed toward Earth.
How fast is the world spinning?
roughly 1,000 miles per hourThe earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second–or roughly 1,000 miles per hour.
What if the Earth stopped spinning book?
Can dinosaurs ever come back to life? What would the earth be like if all the nuclear bombs went off together? Join author Roopa Pai for an out-of-the-world adventure as she creates all sorts of crazy scenarios for the future and explains what would happen if each one were to come true.
Will the earth ever stop spinning?
The Earth will never stop rotating. Earth rotates in the purest, most perfect vacuum in the whole universe—empty space. Space is so empty, so devoid of anything to slow the Earth down, that it just spins and spins, practically without friction.
Can we survive without moon?
The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
