You guys should have consulted with an igneous petrologist before making such a video because it contains terrible mistakes. First, there is no magma ocean beneath the crust all the way to the core. Have you heard of "mantle"? According to valuable data obtained from earthquake waves, we know that mantle is solid on human time scales, but it is able to convect like a fluid only over geological time. Primary magmas are formed from partial melting (5-30%) of mantle peridotites under specific conditions and in specific tectonic environments such as mid-ocean ridges, subduction zones and intra-plate regions. Second, there is no "solid core". Have you heard of Inge Lehmann? Apparently not. The core is divided into two parts: the outer and inner cores. The outer core is liquid and that's why we have magnetosphere and life on Earth. In contrast, the inner core is solid.

Where do the vast majority of volcanoes occur? Y’all have the answer?

[adamrounds]

Why do some claim hollow earth and their are at least caverns 250 feet down i went down one Howes caverns in N.Y.

[Fundipped]

I thought lava could flow as fast as 60mph?
