What would happen to the Earth if the moon disappeared?

The Moon moves away from the Earth about 5 cm each year, which may mean that after about 200 million years, the length of the day will be 25 hours.

In this process, the Earth's rotation is actually slowing down, and this may raise questions about what would happen to Earth if the moon disappeared one day.

The full moon is on average 14,000 times brighter than the brightest object in the night sky, Venus.

So without him, every night would be as dark as a new moon.

And star gazing would be amazing.

According to Russia Today.

But by the next morning, you'll begin to realize just how important the moon is to life on Earth.

Between the sun and the rotation of the Earth and the Moon, the Moon has the greatest influence on the tides on Earth.

Without it, high and low tides would be reduced by about 75%.

This would endanger the lives of many intertidal crabs, mussels and sea snails, and disrupt the diets of the large animals that depend on them for food, threatening entire coastal ecosystems in the process.

And in a few decades, we'll start to see a significant decrease in population at sea and on land.

And one of the world's largest spawning events occurs in the Great Barrier Reef.

Every November in the days after a full moon, coral colonies across the reef, which stretches over an area larger than New Mexico, release millions of eggs and sacks of sperm within about minutes of each other.

Scientists are sure that the full moon plays a role in timing, but how that is, remains a mystery.

On Earth, animals like these red crabs also use the moon's signals to reproduce.

Having lived most of their lives in the mountains, millions of adult crabs migrate ashore.

Then, only during the last quarter of the moon, the females release their eggs into the sea.

The moon may not have the same effect on human reproduction.

But without it, something else we equally care about would change, and that's the weather.

Tidal currents mix the cold Arctic waters with the warm waters of the tropics.

This balances the temperatures and stabilizes the climate around the world.

Without the moon, weather forecasts would be virtually impossible.

And the average difference between the hottest and coldest places on Earth can grow to extremes of life-threatening severity.

Currently, the Earth is tilted around its axis at 23.5 degrees, mostly due to the Moon's gravity.

If the moon disappears, the Earth's axis will swing between 10 and 45 degrees.

Some experts estimate that Jupiter could help prevent Earth's tilt from completely curving out of control.

But even just an extra 10 degree mile can wreak havoc on climate and seasons.

In the past, the Earth's tilt changed by about 1-2 degrees, which scientists believe could have been the cause of ancient ice ages.

It's hard to know what a 10-degree or 45-degree tilt would do, but probably not useful for most life on Earth.

Not only is the moon essential to life on Earth today, as it turns out, the moon is not just a beacon of light in the night sky, and its presence is crucial to the delicate balance that makes life here on Earth possible.
