Hydrothermal vent areas have hydrothermal chimneys, from which hot, mineral-rich water comes out.
(This hot water often looks like black smoke, but it's not really smoke, it just has a lot of dark, microscopic mineral grains in it.)
Where does this hot water come from?
a Ice underneat the seafloor gets melted by volcanic activity, and this extra water comes out of the vents.
b It comes directly from the Earth's core, since our core is made of hot, high-pressure water.
c It is seawater that went down through cracks, got heated by magma, and rises up to emerge from the seafloor.
d Some of the minerals in the Earth's mantle break down and release large volumes of water.
The Earth has an approximate mass of 5.97*10^24 kg and a radius of 6,300 km. If the crust accounts for 31% of the mass and its radius is 2 times smaller, then the density of the core in kg/m3 must be approximately
