Earth's mantle is a zone of hot molten rock beneath its solid crust. It is fluid, but quite viscous, so it flows slowly. It is almost twice as dense as granite. That is why we find so much granite in rocks and mountains here on the surface. Lighter rock floats on top of heavier rock. This is good news for land-dwellers like us.
The minerals and compounds found on Earth's surface can be found in rock from the upper mantle; however, we only know well the mantle rock that has reached the surface. Mantle rock reaches the surface in several places through fissures in the crust and volcanoes.
The molten mantle of Earth contains a higher abundance of heavy elements, like iron and nickel, than does its surface. Mineral compounds obey the same rule as the elements: Lots of aluminum and silicon near the surface, and olivine and pyroxine minerals and heavy elements farther down.
Current theory suggests that the Earth's hot flowing mantle will provide us our magnetic shield against the Sun's harsher radiation for more than a billion years to come.

∙ 9y agoThe mantle is the layer of Earth between the core and crust. It is made up of ductile rock which exhibits plasticity, bends without fracture, and is extremely highly viscous.The mantle extends from a varied upper depth of 5-50 km to a lower margin of 2900 km from the surface.
