Come on there boy!

Ease up a little.

Start by thinking/keeping in mind of how the Magma got to moving in any direction at all.

Ever see Compression/Torsion fractures (think - CRACKS) in everyday rocks. Look around. There are plenty of examples in most Marble Stone work used in Buildings. Go for a walk and check it out!

Well! Now think of what happens when the Source Magma gets to FORCING its way through those Compression/Tortion cracks. Lots of Pressure (with plenty of HEAT added) happening to get the Ball, excuse me, Magma rolling. excuse me again, to get the Magma FLOWING.

There! Got it so far?

Now! Consider any River (Flowing Fluid of any type, but if it makes the imagination work better, keep to the Every Day River types, ie. Water filled Rivers). Next add Meandering of the River Channel. This is where the Compression/Tortion fractures ACT to Control and Direct the Flow Path.

Now, What do you see as the Water flows in the Meandering River Channel?

Think - Where is the Flow likely going to be the swiftest (where does the water flow fastest?)? Where is the Flow likely to be the most Lethargic?

Also wonder what happens to Water under Pressure. To help, turn on a Drinking Fountain at work/public location or the Shower in your bathroom at home?

And doing this MAY help you get over thinking Purely GRAVITY.
