Are there large caves deep underground or none??

Question

Are there enourmous hoolows beneath the surface of the earth, getting bigger the deeper they are, or is it all one solid mass after a certain point?

Answer 1

In general the earth is solid but under limestone bedrocks caves do form. They are formed by surface water which can form streams or rivers underground.The caves end where the water comes to the surface so some are small while some can be large and long..

Answer 2

Yes, I think some caverns continue to grow, the salagtites and salagmites in caves and caverns keep growing, slowly but they keep growing. Or take the Mariones Trench under the ocean, no one knows how deep it is, and for all we know it could get deeper everyday, we just don't know. I would venture a guess it gets a little deeper every year, b/c of the pressure that the Earth puts on it and it cracks or 'grows' deeper.

Answer 3

Go deep enough, and it's one solid mass, because the pressure increases as you go deeper and eventually exceeds the strength of the overlying material. Also, caves are created by the flow of underground water, and that makes it really difficult to have caves much below sea level.

Answer 4

I want the deep conversations. I evaluate myself an psychological, and that i do appreciate philosophical components of existence, so while somebody is waiting and prepared to have a deep communique with me I open it with open hands. The lighthearted conversations are good for small communicate, however the deep conversations are those that I stay for. The final communique that i will undergo in concepts that replaced my point of view on issues became probable with a woman i've got those days met. It became a communique approximately relationships, the destiny, and existence. It does open your eyes slightly greater to what's obtainable. :)

Answer 5

I would think that caves only exist in the earth's crust, but I'm not an expert.

Answer 6

Both are true.

Look at the phenomenons of sinkholes, as well as the earth's core.
