If a large comet or asteroid hits in the ocean, the water rushes back in to fill the void, correct?

Question

So, would that not PREVENT a huge fireball of impact ejecta from happening? Wouldn't we just have to worry about the massive tsunamis the impact would generate?

Answer 1

Large asteroids can be extra deadly when they strike the ocean, carving aquatic craters and sending huge waves in all directions. These tsunami can wreak destruction on shores thousands of miles away. Bad news for people living in coastal areas, but it could be a lucky break for the rest of mankind:The same impact on land would throw dust high into the atmosphere and could block sunlight for many months, possibly causing global starvation and mass extinctions.
Based on NASA estimates, about once every 2,000 years an asteroid with a diameter of about 100 yards can be expected to hit one of Earth's oceans. Larger asteroids collide with the Earth much less frequently -- a 500-yard rock from space might hit an ocean once every 80,000 years and a 1,000-yard asteroid perhaps once every 200,000 years.

Answer 2

What Would Happen If An Asteroid Hit The Ocean

Answer 3

If the large comet or asteriod were to hit the ocean, the immediate result would be nearly complete voporization of the water in the immediate area of impact. The falling asteriod would have gone though earth atmostsphere, heating it up through friction, making it so hot that it would cause such a vaporization. The impact itself would most likely cause several effects, including earthquakes, tsuamnis, and effects to the atmostshere. If a comet was to strike it would cause additional problems. After all comets are made up of dust and ice, all being collected over millions of years. Can you imagine what could be inside such a huge dirty ice ball?

Scientists say that life could have come from a comet since they believe that comets may carry carbon, or water, or other building blocks of life. But what else could they carry through their journeys throughout space?

Eventually, yes.. water would fill the void.. but only after the major earth shattering chaos of the intial impact is way over. And not all the water would fill it back.. a lot of it would have been completely destroyed by the initial impact.

Answer 4

The water would eventually fill the void but only after a huge dispersement of water. If the asteroid hit the water at a 90 degree angle (or straight down), the tsunami would be the biggest problem but if the asteroid came in at an angle and "skipped" along the water, tsunamis and the "bouncing" asteroid would be the problem.

Answer 5

really a small fraction of the Earth-crossing asteroids, ECAs, were got here across and cataloged. Uncataloged ECAs can hit the ambience of Earth by marvel. lengthy-era comets would supply as low as 2 months caution earlier effect. the wear tiers from fires and blastwaves from power dissipation contained in the ambience to craters, earthquakes, and tsunami from floor effect. Tsunami damage is really severe. An asteroid 5–6km in diameter impacting contained in the mid Atlantic would reason major tsunami damage to both Europe and North u . s . a . of america: the tsunami would run all a thanks to the Appalachians contained in the better 2-thirds of america and to the mountains of the Iberian Peninsula in Europe. Tsunami heights alongside the Iberian Peninsula can attain various hundred meters. The tsunami heights will be a lot less in Northern Europe because of the shallow continental shelf in this area.

Answer 6

That is probably correct. I don't pretend to know from experience what would happen, but it makes perfect sense that a water impact would extenguish the heat of the asteroid.

Any yes, we would definitely have to worry about the tsunamis the impact would generate.
