Hello Katie:
I guess what you didn't catch in that presentation by the film
or your teacher was that all this "Earth Going Away" and "Moon
Crumbling" stuff was going to happen in about Four Billion Years.
Hey that is long past when I will be gone from here, and you also.
So why worry about it now?

The world will end when the sun becomes a Red Giant. A recent article pointed out that when the gases of this Red Giant Sun envelop our world the forces upon the earth and moon will be such that the moon will move in closer towards the earth. Eventually this will cause the moon to come so close that it will break up (the Roche limit).
However, this will not occur for at least 4 billion years, and when it does occur the earth's surface will have been scorched so severely that no life will exist on its surface (or oceans, or air). Thus we will not be present to see the break up of the moon.
Sometime after the moon's break up the earth will begin to spiral inwards towards the sun, incinerating itself in the process until it no longer exists.

No the moon won't crumble. In about a billion years it'll slide way out of orbit. It's not crumbling People have been predicting the end of the world for thousands of years. Don't worry about it. The crumbling is bad science.

The moon will crumble when the sun goes red giant in 2 billion years. The earth will be sucked into the sun a few billion years. Before that an asteroid may hit, we don't know yet.

I would not worry about it .No need to think of such gloomy thoughts. The world will be around for a long time.However in 5 billion year it would have increased in size considerably. Let alone the population increase.We do need the Moon ,I wouldnt worry that it will crumble.

I really doubt it, but it's not impossible that some object might just invade our solar system and slam into Earth before the sun has spent it's 5 trillion years left of fuel~!
As far as the sky falling in - that's grade school stuff.

Only God knows when the world will end.
