Hi i have this question in my mind for very long time ,what stops water on Earth from going further down and down and reach the center of the Earth ? i want to know the laws of physics that makes this possible .
These questions imply that Earth should be littered with geothermal power opportunities.Borek said:You are not the first one to ask this question on the forum.
Think: what is the temperature deep under gorund? What form does water take there?
First off, please read this thread: [thread]564079[/thread].vrmuth said:Hi i have this question in my mind for very long time ,what stops water on Earth from going further down and down and reach the center of the Earth ? i want to know the laws of physics that makes this possible .

There is *no* way that water could reach the center of the Earth. The second law of thermodynamics forbids this. If you look at a diagram of the Earth, you will see that it comprises a solid iron inner core, a molten iron outer core, an inner mantle, an outer mantle, and a crust. The densest stuff is at the core, the least dense stuff, in the crust, is at the surface. Why is the Earth layered so? The answer lies in entropy, energy, and the second law of thermodynamics.
Borek said:Now, you can think in terms of water being forced into the cracks, and sinking down. That works only close to the surface, as technically water displaces air, which is lighter. However, when you go deeper, there are no cracks, they are closed because the material is hot and under high pressure.

I think there are fewer passages for water to go down than you imagine. High pressure in the deep rocks is bound to force them together and close cracks. Many of the remaining cracks will eventually be filled by minerals from the water. The water that can still go down may be stopped at a trap, like under your sink or forces from below (steam, etc.) may stop it from descending further. Any water that still makes it low enough will be turned into steam.vrmuth said:Hi i have this question in my mind for very long time ,what stops water on Earth from going further down and down and reach the center of the Earth ? i want to know the laws of physics that makes this possible .
There are a few factors that can contribute to water not being able to go down any further after reaching a certain level. These can include the shape and size of the container, the amount of water already in the container, and the force of gravity.
There is no specific limit to how much water can be in a container, as it depends on the size and shape of the container. However, there is a limit to how much water can be in a container before it overflows due to the force of gravity and the shape of the container.
Yes, the temperature of the water can play a role in its ability to go down further. Cold water is denser than warm water, so it may be more difficult for it to flow down through a narrow opening. Additionally, hot water may create steam, which can take up more space and prevent the water from going down further.
The shape of the container can greatly impact the water level. A wider container with a larger opening will allow more water to flow down, while a narrower container with a smaller opening will restrict the water from going down further. The shape also affects the force of gravity and how much water can be held before it overflows.
Yes, air pressure can play a role in the water level in a container. If the air pressure inside the container is higher than the air pressure outside, it can create a vacuum effect and prevent the water from going down any further. This is often seen in suction cups or when trying to pour liquid from a bottle with a narrow opening.
