If molten carbon were to come into contact with our oxygen rich atmosphere, I believe that it might oxidize and form carbon dioxide.
Oh... and carbon monoxide too.
From what I understand, that's not something that would happen. It takes very high temps for this to take place. Carbon is much easier to combine with other elements, many more, than oxygen. That would mean that it would have to react before it reached the surface.
The upper mantle is the layer that sits directly under our planet's crust, and extends to a depth of about 410 km (250 miles).
Within this layer, temperatures can span from 500 to 900°C (932 to 1,652°F) near the crust, and can reach a hellish 4,000°C (7,230°F) in the lower mantle closer to the central core.
That ridiculous heat is constantly melting carbonates - a large group of minerals such as magnesite and calcite that all contain a specific carbonate ion - and this molten carbon is thought to be responsible for the conductivity of the mantle.
