Leenypoo Hi Leenypoo, You will have to rephrase your first question and send it in again.
Molten lava is usually orange or red.
As lava cools it turns from the hot colors to the dark greys and black. That means that when you see a lava flow that is part red and part black then you are seeing hot lava and cooler lava. Lava cools very quickly at first and in order for it to show a red or orange color you either have to pull off the grey crust yourself all the time, or go to a place where the lava is flowing so vigorously that the crust is continually broken up into small pieces.
