Answer:
well
Explanation:
The Grand Canyon contains some of the oldest exposed rock on Earth. The mile-high walls reveal a cross section of Earth's crust going back nearly two billion years. These rock layers have given geologists the opportunity to study evolution through time
you can search the internet about it
Well, i would say that: <span>because of large deposits of iron ore. they needed to provide there country at least with something, so that is why.
so the final is: </span><span>because of large deposits of iron ore.
hope that this helps you.
have a great day! =)</span>

Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
Water is the source of life. It is one of the only ways to survive so without water, there is no life.
