Heat release from tectonic friction

Hi TC, There happens to be enough water in the lithosphere, asthenosphere and mantel to fill our oceans 7 times. That water had to get there some way, and sometime in the existence of the Earth.God Bless,

Hi TC, Isn't water the the cooling agent that cools the plates as they move?So my point is that the water would have got in the materials between the stationary materals and the moving materials during the movement, and into the mantel during any subduction.God Bless,

Hi No, Any water at the bottom of the ocean that was introduced into the oceanic crust would be able to account for a lot of cooling as it is 1.5C to 4.5 C.But water at 210 can still transfer heat as it becomes steam, as well as superheated steam. And yes the water in the lithosphere and asthenosphere would need vents to expell heat such as those in the ocean and through volcanos, as well as the cooler mass above the water.God Bless,

Hi TC, In a laundry sheets and towels and cloths are washed and then as much water as possible is extracted from the material. But the material still contains water.Steam produced in a boiler is used to heat ironers, and presses as well as tunnels that are used to remove the water from the cloth material.The water first is heated to be come steam and then the steam heats the metal that the cloth material is put in contact with and that metal then transfers heat to the cloth material whch becomes dry,as the water in the material trys to cool the metal. How did that water get captured in the lherzolite and retained in nominally anhydrous minerals?Where did that water come from?God Bless,
